Title: 1974 CB360 Fallin' Ditch Hell Ride
Post by: irk miller on Jul 06, 2016, 13:36:17
One day, drunk, I might've mentioned to Mr. E that I was lamenting the decision to give up my 360. E happened to have a meth head neighbor with a CB360 rotting in his yard. E tried to wrangle the bike from the guy, but the best he could do was borrow the broken top triple so he could measure it up for a custom design. Months went by and the guy decided to move, which made the bike expendable. So, I was able to get it for $25. It amazes me that something could be so important to someone that they refuse to sell it for years. Then when they finally have to sell it, they'll dump it for $25.

I'm not totally sure I need to go down this rabbit hole, but something about these bikes I love. It's probably the familiarity, but who knows.

I went home to the folks house for the holiday, which is just down the road from Mr. E, and drug this pile home.

As impressed as I am with what's bad on the bike, I'm equally impressed with what's good. For one, the motor has nearly perfect compression. The bike sat for years with no air filters, but the choke is frozen shut. That motor was all sealed up like King Tut, and left full of oil. There's an obvious amount of rust throughout, and nearly 12k on the clock. One punch mark on the motor vin plate, but not a single stripped or warped screw anywhere. The carb boots are somehow supple and seem nearly new.  The rims have little rust, but we're converting to some Suzuki aluminum rims anyway.

Since the top triple is gone, I went ahead and began work with a front end swap. An SOHC CB750 swap is pretty damn easy, and with 35mm fork tubes it's no doubt more stout. We'll upgrade the guts to get a more modern rig.  I already had a custom top triple machined by Mr. E.  I also happened to have a minty fresh CB360 tank that Von Yinzer sent to me a while back.  It's like fate or something.

A million things need to happen, but nothing before the suspension is sorted. The motor may happen this fall, but I suspected it'll work itself into a winter project.

Yep, it's weird but there is something about 360's that makes them fun
I've always thought it's like a reliable Triumph 500 twin as it's about the same size and power output (but less torque)
My brother had 500 for years. (he got pulled for 10mph over the limit one morning and cop said he had enough problems as he was riding a Triumph so wouldn't give him a ticket  ;D )

Thanks y'all.

I began the conversion on the rear end. We'll at least make this thing a roller. 90s era XL250 Pro Link swing arm converted from monoshock to twin. We're adding about 3/4" to 1" rear travel, and balance with the CB750 front end.  The Pro Link is also 2" longer.  I'm not beholden to these Redwing shocks either.  They kinda suck.

This has become a sweep the floor bike. So far, the shed supplies.

I had to fix the XL175 seat when I cracked it wrecking on a deep gravel swamp road.  It still needs some massaging, but it's gonna fit real nice. 

Also moved to a complete XL250 rear end.  They ran 18" rear and alloy, plus the  brake stay matches the swing arm. I just need to adapt the pull.

Dropped the top shock mount 1.5" to get some lift in the rear and to balance the frame with front end.  We'll keep the threaded ends for turn signals.

XR swinger will be nice, PJ.

I'm a fan of the square hoop these have, so I split it and took about 1.5" out. Welded the two sides together in the middle for a bit narrower wedge shape. Now I'm reshaping the seat pan to match. The XL had a wider, round hoop.

I got the Suzuki rim laced up to the 360 hub. Now we're 18in and aluminum front and back, wrapped in 120/80-18 Shinko 705 tires. The hope is this setup will be good on sandy or deep gravel back country and swamp roads., which makes up the bulk of country roads around here.  As soon as the brake parts come in, I'll start the dual disc front end conversion. Also mulling rear disc...

The brake plan is duel disc up front and disc rear. I also want rid of the thousand pound, undrilled stock rotor up front. Through some searching, I discovered that the CB's disc rivet pattern is the same as an EX500 bolt pattern.  So, I separated the stock disc from its center...

(http://uploads.tapatalk-cdn.com/20160720/7064cce9f2fdc4344b292d492c36a9ce.jpg)

Drilled out the holes and tapped them for 8mm X 1.25, so I can use the EX screws. Machined the centering tabs to accept the smaller EX center hole...

Really liking what you've done so far with the front disk.

I'm contemplating something similar for my 360 cafe, but my engineering skills aren't as good as yours I suspect!

Is the ex500 disk the same diameter, so will work with the standard 360 caliper?

If so that looks like a great mod, either single or especially double!

Thanks Steve.  It really only takes removing the rivets (a grinder will do it), a punch to kick them out, a decent drill press to slightly open the holes, and a tap.

It'll take a special bracket for the calipers to fit a 360 front end, though.  The EX rotor is 20mm larger.  But since I converted the front end to CB750, I can use the stock CB750 calipers.  The 750 rotors are within a half cm of the EX. It takes very little effort to swap the front end.

Thanks for that useful info!

Next big job on the 360 is a front end upgrade, 33mm forks are way too flexible!

I believe the 750 front end fits, but is longer than the 450/550 so these are more suitable and still 35mm with the option for dual disks?
This combined with your ex rotors is my preferred option right now.
Do you know if the 450/550 have the larger or smaller rotors ?
Thanks for the advice!

I think they are 270mm.  You'd have to confirm.  They look the same and have the same bolt pattern as the 750.

Got the other disc done, so now we're dual up front. Sourcing the rear disc is harder than I thought, but I've managed to narrow one down to an NSR250rr/VFR400/RFV400. I have a range of 4 X 105 - 110 and those come in at 4 X 110.

Inching toward some kind if a plan for the rear brake. Since it's laying around, I'm starting with a Nissin rear brake that was bought at Mid-O last year.  I machined a spacer to press into the brake mount and cut some extra meat off. I'll need to go with a bar stay, since the machined groove on this doesn't line up with the XL250 swing arm stay...

I may carve the bracket down more, but I want to see if I can use it for the license plate or something first.

I changed the back of the frame and the rear hoop. Brought the frame in and pushed it up more. I'm still trying to get good at bending pipe with heat too. Bent up this hoop, which still wrinkled a bit inside the corners. I need to clean up the seat, but this is close to being right...

The EX bolts are 6mm longer than they need to be, but the shoulder is for the the EX disc not the center so it fits fine.  I cut 6mm off the bolts and I'll run a nut on the inside of the 360 center.  I'm not sure why you did the spacer, either.  Did you run a front end that needed an offset?

I didn't get the bolts with rotor so used GSXR flanged Allen heads.
 There was a different reason I made spacer, maybe to move disc away from spokes so I can use 4 pot calipers?

Here's what we have so far...

(http://uploads.tapatalk-cdn.com/20160806/ef142fea1bf37a3baca4af248354644e.jpg)

4 bolt pattern for the disc and 5 bolt pattern for the cush. I'll cast 85A urethane with threaded inserts to fit the hub. Fortunately, the hubs are webbed to set up nicely...

(http://uploads.tapatalk-cdn.com/20160806/a420c1a3cba9cbbafa95ca82d96708ba.jpg)

And with an NSR disc...

(http://uploads.tapatalk-cdn.com/20160806/92ff0c4ff9d99741809c9572054ceb80.jpg)

The hub side is machined to fit over the center of the hub, the brake side center is machined for a 52mm X 17mm X 15mm bearing plus dust seal. Bearing and urethane on order, and hopefully will show up this week.

;)  Just using the hub as a mold, since it's there.  I'll get the hardware together on the carrier, mix and pour the urethane and let it set.  It'll pop out and have the shape of the interior of the hub.  The hub is held tight by the axle, so it really just needs to be held from spinning.

Thanks, Doc. I agree.


Time for front caliper mounts while I wait for stuff to finish the rear. I ground away some of the CB750s fork lower and drilled/tapped through the stock mount. I'm running a bracket topside through that hole plus the fender brace hole. This is a functional mockup, as I want to be able to run it to test, but later mill it in alloy.  I cut and shaped the bracket in 1/4" steel plate, plus machined two 25mm spacers to offset the caliper, which will get welded in place...

I think this thing is fucking with me. Perhaps the best way to store a vehicle for long periods of time is in some rednecks yard, on it's side, clutch side down. The clutch looks good, and soaked in oil. There's a little sludge, but not a lot, in the oil slinger and the bottom of the case. ISO: CJ360 pickup. The gasket popped right off and looks nearly brand new. Go figure...

The biggest question mark so far. The cylinder walls look good and the compression was as it should be for a low mileage bike. However, the pistons look moist, so oil may have skewed my reading...

Since the GL is timed on 90 degrees like the 360, I'm trying to adapt a GL Dyna to this 360. I trimmed the Dyna backing plate down to 62mm, machined a socket screw down to give the sensor clearance, ovaled the center hole on a washer, and grooved the base of the right sensor. All because the right sensor covered the right fastener. Next, I'll trim down the reluctor to match the 360 cam...

Let's hope so.  I wonder if heat is a culprit to failure.  I have two versions for a CB750- a newer and older version. Both still do well. If this doesn't work, then there will be a version 2 made from the sensors out a Toyota 22re distributor and a GM HEI module.

Finished up the rear hub. Faced the front off the Honda bearing retainer to press in the dust seal and filled the hub with 85a urethane. 5 100mm cap screws are inset in the carrier with shoulder bolts cast into the urethane. On the front end, I'm thinking I'll drop to single disc. Plenty of stop and I'm a bit concerned on losing the gain I've made in weight loss. I'd rather go less on the unsprung weight of two calipers and discs...

I honed them and it's all really smooth.  The only place you feel any depression I circled in the pic, which I think is below the rings.  When I tested for compression, I had really good numbers, too.  I'll probably just replace all the rubber and gaskets and button it back up and see how it runs.  It's not but a few hours work to tear it down again.

 Used pistons, cylinders get bored and honed to fit.
get new rings, (aftermarket work fine, I've been using 1.00mm oversize and gapping them with a gapping tool I bought ? yrs ago (1mm over was cheaper than stock size  ;) )

Yeah, I checked out the eBay ad where you bought them (search on "Sold listings") and if you look really really close at the picture you can see the one was broken, though it looks like they tried to turn it at an angle so it would be hard to see.  I think you're probably lucky they worked with you.  (Speaking of eBay and GS850 pistons, somebody has a set of four of them on there right now sitting at $29, great deal for a couple of the other 360 owners on here!)

Any way, carry on and get that thing built!

They accept returns and exchanges and the listing wording was for a usable piston.  They really should've accepted the return or exchange.  I did admit that I never saw the pic with the damage.  You had to scroll way down, which I didn't do (stupid on my part). 

I'm mailing out the jugs tomorrow.   ;D

they also have completely upside down physical propers of objects in motion etc hence the  beyond idiotoc packing
back to making mistakes
this one rotten dicklick negger buyer , he negged me without a single note it was a kickstart shaft and gear rm125 he recieved it with a tooth missing
the pictures 6 of them i put in the listing all hid the broken tooth
the cocksucking negger  i called him i had 4 more on the shelf was ready to send it,if he would remove the neg
he wailed you tricked me  !!! you purposely hid the broken tooth !!
fucking insane ,man
it was a completely honest fuck up on my end ,and a perfect storm of fail,i was ready to send the replacement but tried to explain it was a mistake fer fucks sakes it was a 25 doller part
nope he was not gonna revise the feedback i told him he was a pos and hung up
insane,man,a fucking madman
one other time a carb a very siomilar situation only it was just missing a idle speed screw
i called the guy up and sent him the part but i am pretty that pos still thinks it was premedidtatered act on my end

Sidebar... On topic, I did measure for all to know the KZ1000 pistons to see if the pin and crown would stuff and were a mm from pin to crown but a flattop may just wurk with a little rod work if the bore can take 70mm

850 Pistons in the fresh bore. Mototech, who machined the jugs, said the stock head gasket will work. I'm inclined to agree.

Nah... I would set the head on and snug tight the bolts just to settle the gasket and squish a ball of silly putty.  If it were me I would chuck the piston up and trim that or use a copper base gasket to set the deck up more.

Post by: crazypj on Sep 17, 2016, 16:36:55
Have you got an old 'squashed' gasket to measure?
 I'm pretty sure edges will contact piston when torqued down which is why I always use solid copper with CopperKote gasket sealer. The other reasons for using copper gaskets, better heat transfer through head and block into crankcase (about 6 times better than the alloy and unknown amout better than fibre gasket), plus they are re-useable

Just noticed your question about 71mm piston. Can't be done without a load of work.
Almost sure you use CB450 or 500T pistons as three valve 400 pistons are too short and flat top so compression is around 6:1  You will need new liners as they can't be bored far enough. Get a used Suzuki GS1000 block as it uses 70mm pistons (It's been a long time since I did the measuring)

When I ordered mine from Lani I first contacted him through eBay and then ended up ordering directly from him.   He wanted to talk w/ me, insisted actually, and then after we had everything worked out and agreed to, he asked that I send him an email stating everything we had agreed to.  No problem, I figure it's better to make sure everything was correct the first time.  I recommend you stress the 69.5mm bore, though, because even after we discussed that and it was in the confirmation email I sent, Levi and I found the bore of the gasket I got had to be filed a little to insure a good fit w/ no piston interference.  All of my dealings w/ him were easy and professional and he was friendly and polite.  The gasket arrived very quickly.
Title: Re: 1974 CB360 Fallin' Ditch Hell Ride
Post by: crazypj on Sep 23, 2016, 23:41:57
Lani hasn't changed, he really likes talking with customers.
 I know for a fact he did a 'run' of CB360 to 378cc head gasketts about 6~7 yrs ago, I think it was 8 or 10 at one time? (I bought 2 as it's 'cheaper' and more accurate than cutting them from copper sheet (sheet was $17.00 then several hours cutting, drilling, filing)
May not sound like much but for a bike that's been out of production almost 40 yrs and was never very popular............................
 Pretty sure he's done a lot more since then.
 I forgot I sold some cylinder blocks bored for 69mm (with GS850 pistons) about 7+yrs ago, No idea where they are now though or even if they got built into complete bikes?
I never thought there would be more than 3~4 'in the wild' plus what I built for myself  but pretty sure there are at least a few dozen by now? ;D

Do a better job of getting oil to the top end. Plus, the plan is to eventually convert to an external filter.  I will tie into this system.

it would be prudent to have an anti drainback check ball valve in the outgoing oil line
another thing to look at would be tightening up the escape route for oil that makes it to the cam journals
you can pump lots of oil up there but if it too easily just escsapes duty it isnt doing much good

How does that work? Doesn't the pressure from the pump ensure the flow is only one way?

the extra plumbing and oil cooler takes a certain volume/time  to fill, if it has to be filled every time the engine is fired well thats not optimal
a checkball valve can eliminate the situastion,nip it in the bud it doesnt even need spring loading if mounted so gravity helps its fuction ,something like this cheap insurance

A very important consideration on the 360, which can take almost a minute to get oil from the sump to the head.

This isn't a system to replace the existing circuit, it's just an added path. No cooler, but a reservoir to increase capacity by a quart.  The reservoir will act like a regulator. It will stay full, and flow once pressure is reintroduced. I didn't turn it into a dry sump.

An accumulator isn't flow through.  It's a reserve that allows you to add oil into the system, usually by compressed air.

yep they can save an engine in a situation where the pump starts gulping air

It's been done many times.  Just another way to compensate for the machine's notorious oiling issues.  I've done PJ's internal mods on a stock machine, and this motor has had the stock galleys opened up.  I'm just taking it another step further with the bigger bore and eventual cam upgrade.  I will likely add the cooler at some point, and include a check valve if that happens.   I may end up adding in a pump, too.  First, I want to see where this takes it.  Here's a version of the mod with a pump:

(http://i1086.photobucket.com/albums/j449/trek97/DTT%202014%20spring%20tune%20up/ScreenShot2013-11-16at91522PMpng_thumb_zpse5a29504.png)

 It should keep the motor temps lower, external cooler or not.

So you're increasing the total volume of oil within the motor, opened up the stock passages, and have oil flowing to the top end through the external tank -does that result in lower pressure through the filter/galley and external reservoir?

If the pressure is now essentially split between the two channels, will there be enough pressure to get oil up top through either route?

2 chunks of pipe and a belt sander to make a crotch... make the notch cuts and weld the kinks in the 2 after sanding then weld the crotch up with birds beak then cut that off right where the dia is close to the mega slip.

srsly cool bike
also srsly the brake arm i'm not saying it will fail but if i was gonna design one leaving the fail door open  i would copy that
it will probably be fine as long as you keep a few micro grams of air in the brake line
but with sticky tire on pavement and you panic stomp. or just playing back it in ..............
see, i have personal experince and have seen a swingarm bent up at 90 degrees on oene side  just from the bolt coming out of the stay arm and as the drum brake plate rotated it clamped on the brakes and it was on dirt
safety issue dude thats all,as soon as you put a  bow  in a compression member all normal thoughts of strength fly out the window
it allows initial flex, thats what leads to the failure ,well not failure continued bending ,its like it gives the energy momemtum, to try to exsplain it and the more it bends the weaker it gets
im just sayin theres no reason to have it be a weak part
you could seeze the oportuinity to make something artful AND trick looking and strong by going around both sides of the shock with an oval hoop (round was my first thoght but the shock tilts a bit during travel)or a girder section

 i did know kenny worked with S&W that was his rear shock sponsor,those are s&W on the rear they were very good in the day
what i did not know was that his tt bike shown here, tt has a jump you know,i did not know he ran long travel suspension on the TT bike you can see that in the length of the rear shocks and the amount of exposed rod
the front forks are 78 or so yz forks notice the leading axle i am guessing they were shortened a bit from stock but his wheel travel is at least 7" front and back could be 8 this would give him huge advantage over  the old school harleys tri and bsa that had 4-5 inches tops his ease control when landing the jump must have gained him a second or 2 per lap(http://www.650motorcycles.com/XS1976Kenny.jpg)

hey i admire your skills in getting shit done quick but here i go again
i am not making it up but the connection point has a very poor moment
the caliper has my guess and its close, 3-4  times the leverage on the hanger of stay,you welded on the
swinger than it would if it was a correct angle of moment see both kenny's lashups kr and me and view any others
see the force that the stay is trying to overcome is directly related to the path of the caliper if it was allowed to rotate with the disc
between the axle the axis of it and the center of clapper pads contact and the attachement point if you draw 2 lines it is way off 90 degrees
90 degrees is optimal when adjusting chain this angle changes a bit you just want it close to 90 and the attachement point on the clapper hangar for stay needs to be as far as practical from axle center

its like if you could drive a post in the ground with 50 ft of chain and a big fucking hook and you did the calculations and everything will hold with a bit to spare to stop the train as long as the post is center on train track but you cant have it that way so you plant the post right as close to the tracks as you can not 30 ft from the tracks if you do the train then has nearly 2to1 mechanical advantage
if you were to put a triangle gusset in front of that sweet piece you welded on, 3/32 is plenty thick ,run it full legth of the arm you welded on and forward 6" with speedholes,it look great and it could eliminate that flex which will ,lead to failure,because  the way it is now it is being bent,with a past 45 degree sideways motion not pulled straight shot tension at all ,it is being more bent than pulled ,and with a high  leverage ratio, the bending is happeniong,when the brakes come on
but it is just too wrong to use, everything is overloaded when it simply need not be,thats all
besides have you observed when axle is slid fr to back like for chain adjustement ?what you have effects a much greater change than it would if done like i promote

Alright, so making sure I get ya.  I have three potential hanging points highlighted.  Three potential stay positions and directions marked by arrows.  If I understand, the best mount and direction laid out is #1, which also means a stay of about 12 inches mounted with clevis.

If you look, it's a CR hanger.  So, it's setup to to fit into a groove on the CR swinger.  The caveat is that the rotor hub I machined does not give enough room on the interior of the XL swinger to make that design work.  That's why I'm retrofitting a stay option on a swinger that wasn't originally designed for a stay.

It's difficult to tell from the pic, but "F" is a connection to the upper shock mount. Depressing the rear brake also compresses the suspension, keeping weight further back on braking.

Doesn't change the fact that nothing in that pic will work with this wheel, rotor, carrier, caliper setup.  That's also a dual caliper setup.

Every bike I've seen with caliper torque near axle has severe wheel 'chatter' under any hard braking. It works real well when just 'dragging' brake  but hard braking  just makes things jump around. Best way to do it is have a bearing in center and a parallelogram arm mounted to frame.
 Back inthe day several dirt bikes had that set up and it worked real well on any surface. Should be able to find pictures of YZ250/490, Maico 490 or similar.
 It definitely is a major advantage in my opinion, I have experience of the superior braking allowing me to almost keep up with a few professional riders  for a lap or two ;D (on my Maico, the YZ490 was nice but only 4 gears when it needed 5)
 Here's a test on 1981 maico, engine same as 82 but 82 had monoshock with Cortecosso shock which wan't very good (even though Ferrari use them)

Is that the inlet or outlet? I modified a cover similar fashion but used the 'front' plug for the outlet and that hole for return then did some mods internally to get full flow back to main gallery.
Don't think I ever took any pictured of it though?

That's routed to the external sump and top end.  Relying on the return internally.  I'm not bypassing the filter or plugging the idler gear circuit.  Just adding another path for oil to the head.

(http://uploads.tapatalk-cdn.com/20161201/874b5af020bd26fab2cc5854e120c479.jpg)


I have since replaced the barbed fitting with a 1/8"MPT to 6AN 45° fitting on the side cover and a 1/8"MPT to 1/8"MPT fitting on the rocker cover. Then on the rocker cover, that 1/8MPT fitting goes to a 1/8FPT coupling to a 1/8MPT to 6AN 90° elbow fitting.  The hose has 6AN straight swivel fittings on both sides.

I think you'll need a restrictor in the line (although I've considered doing similar mod and having crank fed after the oil goes to cam bearings/cam,)
Block off the passage at rear of cylinders between clutch cover and crankcase so oil still gets into the main gallery and centrifugal filter but doesn't feed direct to it.
Oil coming down cylinder studs will still get to main bearings and transmission (which won't happen if you block the crankcase drilling’s to studs)

Nope, the hole just in front of cylinder base that goes all the way through to alternator cover.
It's kinda triangular/rhomboid on clutch side with a hole drilled through
The weird shaped cut away on alternator side is for tranny lubing
 You already posted a picture of it, I went back and found it. Blocking the 'outlet' would force all the oil to go directly to the head  then lowish pressure plus gravity feed to everywhere else. Probably need at least a 10mm bore hose for it to work though?


I think this thing is fucking with me. Perhaps the best way to store a vehicle for long periods of time is in some rednecks yard, on it's side, clutch side down. The clutch looks good, and soaked in oil. There's a little sludge, but not a lot, in the oil slinger and the bottom of the case. ISO: CJ360 pickup. The gasket popped right off and looks nearly brand new. Go figure...

Yep,that's the one.
AsI've now been thinking a bit harder about it, I think I will modify cover or crankcase to feed cam before anything else and make something to fitinto the 'hole'. I'll probably just have a screw in plug with a 1/16" hole so it still feeds some oil through there and will make system self priming (I think there could be a possibility of air lock if hole is just plugged?)

Thanks, Matt. I knew Mydlyfkryzis posted that in Hondatwins, but it was buried somewhere in a place I forgot about.


A $6 starter delete, which is nothing more than a 41mm - 44mm expansion plug used in intake manifolds, amongst other things.  I imagine a freeze plug would also work.

I was thinking about doing something similar.  What I have drilled now should at least fill the right-side galley, but I have considered tapping the other side to fill the second galley on the points side.  When Logan and Kiley did their 360s, they did it a little differently I believe.  I know on Greta, Kiley made a rail and tapped both sides of the rocker cover at an angle directly above the outer journals.  Logan only did the right side.  When he and I talked about a plan for this one, we decided to move the tap up to the flat side of the rocker cover, which will pour oil through the rockers and into the galley.  Regardless, it's bringing another avenue of oil to the top end, but how effectively remains to be seen. 

I have not drilled the cam.

I've 'gun drilled' several cams now to get oil into proper places. Pics in the 'blog/build thread somewhere towards the second half.
Eventually I'm going to drill through the end of head and cam cover, make a plug with seals and have banjo bolt squirt oil directly into end of cam ( not because it's 'better' but just because I can  ;D )

Haha.  I want to give this solo seat idea a look.  Going back to what I envision for the purpose of the bike, which is a gravel/sand road beater, it makes sense to have a solo seat and rear rack.  That describes more of a scrambler than a tracker.

Leave it to PJ to rain on my BBQ. No worries though. In the spirit of being cheap, I dug out a couple of coils that didn't work and "rebuilt" them. I broke off all the epoxy around the base of the plug wire and the connectors. Then I cut off the ground and power wires, leaving clean terminals. I twisted and pulled the spark plug wire out of the coil body. The plug wire is pushed onto a pin in the same way the plug cap is done. I drilled out the plug wire hole to 8mm down to the pin. Then I pushed the plug wire in, checked resistance (9.5k ohms), and epoxied them in. I checked resistance again before the epoxy set. Then soldered the lead wires- one with yellow, one with blue, a black/white, and a black. Put new NGK resistor caps on, checked primary resistance (14.5k ohms), and secondary resistance (4 ohms). Lastly, I coated the solder connections with liquid rubber.

You can use the small ones if you toss in a 2Ω or 3Ω power resistor. 50W should be enough, but 60W would be better.

Thanks, Tune.  The plan for the seat is something like the early KX/XR/CR seats.  If they'd fit this frame better, I'd just fit one of those.  So, should be plenty of pad. May see if I can find a cheap pad and use it for the foam.

Got it all wired up and lit it on fire.  Amazingly, this GL Dyna works like a charm.  Needs some adjustment in the carbs and the seal behind the advancer leaks like a sieve.  Fortunately, I bought all the seals, so it just a matter of swap . I hope I can do it without loosening any bolts.

Well, it ran on one cylinder because the Dyna rotor needed two opposing magnets instead of just the one it had.  I should've known, but it took me flipping the rotor to realize what was going in.  For some reason having two sensors at 90° is all I though it needed, but it's also 2:1 which requires the extra magnet.  So, I drill a hole opposite the other magnet and epoxied a tiny fridge magnet in.  Now, it actually runs like a 378cc bike should run.  A little rough at the low end, so I'll double check the advance and move on to the carb tuning.

For sure.  PJ's carb mod does wonders for the stock motor, though.  This also has an XL250 44 tooth rear sprocket, as opposed to the stock 34 tooth CB's came with.

Some people might disagree with this timing procedure, but it seems to work:

(https://uploads.tapatalk-cdn.com/20170613/9eba455e0903d6fa887c15251712a5ea.jpg)

For the left side, I plugged one multimeter lead into the yellow coil plug. The other lead to the neg on the battery. Rotated the motor to the LT on the compression stroke. Slowly rotated the Dyna until I read battery charge on the meter. I double checked with the crank. Repeat for the right side with the blue plug. The sensors are set at 90°, so they shouldn't need an adjustment, and there wasn't. I made a mark on the Dyna and a corresponding mark on the case. In order to fit the Dyna cam  onto the end of the CB360 camshaft, I had to machine it down. It's much shorter than the GL.  This made it virtually impossible to advance the cam according to Dyna's procedures.  I made small protractor to fit the Dyna and measured 15 degrees of advance, made a mark and ran it. Then I moved it back 5 degrees and I'll run it again in the morning. This is a lot like timing my truck's 350.

Trying to figure out definitively if this bike can be run with a single, two lead coil as a wasted spark.  Forum searching shows results from HondaTwins that suggests not, but as a 180° parallel twin, I feel like it should.  Might just have to try it and find out.

It would be tricky, but I think possible.

The main problem is the short duration between the firing of the left and right coils, but an occasional misfire of the right side might also be a possibility.

The problem we face is charging the coil field at high RPMs. In four cylinder bikes and 360° twins, you have a longer charge cycle between coils discharges: 360° of crank rotation instead of 180°. Moving to 3Ω coils would help. You might notice ignition cutting out on the right cylinder as RPMs increase into the upper ranges. With the stock setup, you're getting about 6.3 milliseconds to charge each coil (dwell) between firings at 9500 RPM. Halve that for the right cylinder if you go with wasted spark. Typical dwell time, depending on the coil, is between 2ms and 5ms to hit a 100% charge.

The other issue would be potential pre-ignition of the fuel. When the left side is nearing TDC and firing, the right side should be nearing BDC with a cylinder full of fresh air and fuel. It probably won't ignite until compressed, but it might, from time-to-time.

Leave it to PJ to rain on my BBQ. No worries though. In the spirit of being cheap, I dug out a couple of coils that didn't work and "rebuilt" them. I broke off all the epoxy around the base of the plug wire and the connectors. Then I cut off the ground and power wires, leaving clean terminals. I twisted and pulled the spark plug wire out of the coil body. The plug wire is pushed onto a pin in the same way the plug cap is done. I drilled out the plug wire hole to 8mm down to the pin. Then I pushed the plug wire in, checked resistance (9.5k ohms), and epoxied them in. I checked resistance again before the epoxy set. Then soldered the lead wires- one with yellow, one with blue, a black/white, and a black. Put new NGK resistor caps on, checked primary resistance (14.5k ohms), and secondary resistance (4 ohms). Lastly, I coated the solder connections with liquid rubber.


Sorry but it's probably better to fix it now rather than break down in the middle of 'somewhere'  ;)

Not sure how well the pics show it. I filed a shallow groove where the sensor and the baseplate meet. I machined a cap screw head down to fit and I ovaled the hole on a washer.

I like the way you mounted yours better.  I might have to steal that.  Much cleaner and prettier than what I've done.

We'll see how long this one lasts.  Only reason I went through the trouble was because I already had it on the shelf from a trade several months before.  I've tried to keep this build under $500.  My GL won't see the road for at least another year, either. Up to this point, I've been running it with no cover.  I made a spacer to gap the cover so it clears.  Thought about just making it so the cover stands off.

I'm not confident I have the timing sorted on this thing.  It's not running as good as it should, that's for sure.  I haven't messed with jetting yet.  Just the timing, idle and air mix.  It's close.  I noticed in your pics the gap between the modules on yours is before 12 o'clock.  Mine is after.  If yours is timed in that pick, then I think i am way advanced.

Yep, it was timed properly there and good for about 115mph (then Brendon 'got scared' as he's never been that fast on any bike before)
 You need to put a strobe on it and check full advance, I think I restricted advance about 3 degrees (welded a blob on stops and filed it back down)

Leds have a very different beam pattern a require a mirror and lens and normally a reflector that actually put the light where it needs to.

I love you ingenuity but brighter isn't better.  A lot of science and research goes into sealed beams to perform with the incandescent bulb in them.  I'm not trying to rain on your parade, but you might find that the reflector scatters the light more than focuses on the road in from of you.  It's all about cutoff and focusing on the ground in front of you where the road is coming at speed.  If you don't plan on using it at night, it will probably do great as a drl but I dunno if I would trust it for a night ride.

I have done tons of led and HID retrofits, when I first got into it I thought it was as simple a bulb swaps, but there is so much more.

Head over to the retrofit source and read up on some of the forums, there's tons of great info and quite a bit of moto related threads.  A lot of guys are really knowledgeable.  If you email the guys at the store, they are always more than happy to help and "dumb down" some of the science to help you make proper purchases and they are amazing in the customer support side

Thanks, but I've had that stuff bookmarked for years.  This isn't the first time I've done this.  Have you ever ridden a 1974 CB360 with a stock lamp?  Testing has proven it to be much better than stock.  It's not intended to be permanent anyway.   I'll probably convert to the 35/35 halogen.  I appreciate the ad, they're 9012 is not far off in price from what the 35w halogen goes for.

Yeah I have a stock 71 350 and I know the lighting sucks... but I don't really ride it at night because of that.

I have retrofitted a couple BMW and Toyota led projectors into cheapo eBay clear lens (sealed beam replacement) housing with great results.

I used to work for CREE and that's what got me into led swaps and retrofits in the first place I headed a team that looked into providing the oem's with led headlight technology, but we ended up passing on it and now focus strictly on providing the chips.

No excuse for how good or bad this setup is, but this bike won't see much night riding either.  I'm building it mostly to plod around local national forest fire roads and sand roads.  Most of the rural roads and swamp roads around here are sand or gravel.   There are some great places to get to, but sketchy as hell on most bikes.

Have you ever ridden a 1974 CB360 with a stock lamp?  Testing has proven it to be much better than stock.

This is worth repeating.

Much thanks.  Still not tuned as I'd like it.  Plan is to go to a 28 or 30mm VM Mikuni.  I need to get in touch with Murray about it.

I found 28mm Mikuni VM carbs at the Barber swap. Apparently they came off a BSA or something. After machining sleeves to adapt them, I got them installed and ran it. It makes a huge difference in how this bike runs...

I’m actually coming down to 28 from 32. I know a couple of guys who ran VM28’s on the 378 with great results.

I can’t remember if you went to 378 on yours.

Yep, and a tracker seat isn’t the right look for a Desert Sled.  I built it for the sand and gravel roads and realized a Desert Sled is pretty much the same thing.

I made sleeves and shrunk them on to VM carbs for the 390 I had,  (70mm bore)  worked better than expected with zero air leaks. The variety of intake manifolds wasn't available in late 80's so I used stock ones
It was a 120mph 'ratbike'
 Surprising just how good it looks in the pics, deeper seat is probably way more practical for off roading and different enough to state bike is used rather than 'shown'

I have a bad habit of trying to make things from what I have laying around so I don’t have to buy parts.

I got the pipes all welded up from stock headers and a CRF450 header plus one that came on my XL. I cut open the stock muffler to salvage the small perforated tubes, then machined end caps.

It sounds good, actually.  Admittedly, it doesn't sound as good as that other exhaust.  This one is more throaty where the other one was smoother and quieter.  I'll put that can on the DR, I think.

Couldn't get much more than bog at WOT.  Turns out these VMs had a 190 main jet installed in them.  Way too big.  Dropped down to a 130 and moved the needle up one clip (on ring below center).  It's seems very happy right now.  It's still pretty buzzy though, so I think the carbs are not quite synced.  This big ass sprocket is making it quite the quick shifter.  I'll have to decide how it wants to play and figure out if I need to go smaller.

Haha, this is loud. Not illegal loud, but it’s loud. I’m going to work on the baffling to see if I can get it toned down more.

I ran it through some paces in the hills where I grew up. With this sprocket setup, 1st gear is useless on street. It’s super short shifting. Top speed is 80-85mph.

 I think the jetting needs to drop to 120 or 125, if there is a 125. 130 is close, but not quite right. I raised the needle, but I think that was a mistake. I’ll move it back to the middle, run it and see if the clip needs to drop one above center.

Here’s a glamour shot from the weekend on my Gramma’s property. An area in the piedmont of upstate, South Carolina nicknamed Dark Corners...

goes up in 2.5 increments

125 127.5 130 132.5 ect till you hit 200

in the video it still sounds a bit boggy or timing late

and if your needle is that high you may want to go a bigger jet needle or needle ?

what do you have and are they both the same

how is your idle to 1/4 mixture

what slide do you have both the same ?

in a small carb like that you may even be in the right range to go to a bleed type jet needle (4 stroke type)

for better atomization and economy at same power levels

they dont make them in the size ranges i usually use but they might for your range

Thanks Murray.  I think I lost sync on the carbs (or I never had it).  It feels too much like a buzz box.  The idle seems good, nice and smooth and with good rpm.  No starts without choke.  When I set them up originally, I did it in Augusta when it was still in the upper 80s.  The day of the video it was low 50s and wet, plus I'm in the foothills near the NC/SC border.  Not sure how much any of that factors in.  I haven't looked at the numbers on the needle or the slide, but I can pull the carbs this afternoon and check everything I have.  I was hopeful I could get by with just a needle position change and the main jet.  The plugs look good for whatever that's worth.

meh good plugs on mikunis mean your not close enough to the edge lol

but i would quickly strip them to make sure they have the same parts and you are not chasing a mismatch

then go from there

to small a slide it will run ok but not produce the power it can till 7/8 to wide open when the slide is above the venturi

Post by: crazypj on Dec 12, 2017, 19:10:56
cxman, what do you mean by too small a slide? The cutaway?
The 2.5 or 3 in almost every Mikuni VM is too big a cutaway for 360/378 and gives a bad pick up/acceleration. Smaller cutaway gives higher airspeed over rimary choke and can cause too rich a mixture when accelerating, that's when you need a bleed type emulsion tube. You can get something very close from Yamaha RD350/400 aircooled or some of the earlier two stroke 350 'Banshee' ATV's, late models had some weird carb mods and I can't remember if emulsion tubes are the same?

Yep, can't remember specifics, probably have it written down somewhere?
There is a lot of misinformation on VM modifications, much of it written by peole who don't understand how a carb works. You can make almost anything run and seem OK until you try something that is actually running properly.
I have several sets of VM's in various sizes (mostly for XS650's) the ones that 'work' all have emulsion tubes not 'primary choke'. I think I posted about it in 2009 or 2010? Photbucket has screwed everyone though so I'll re-do post when I get time and inclination.
Just spent some time getting software and did section of VM manual showing both types of needle jet.
Not quite the picture I wanted but OK

These carbs are much closer than I've been so far, but there's certainly a lot of work to do to get them right.  It has some spots where I think it goes lean.

With our tiny Hondas we tried all manner of needle jets and even when we thought they were running right with Pilot types, the amount of unburned fuel was way too high.  So we went to bleed types and that improved fuel atomization and made slightly more power while using less fuel. There's another page from an old manual somewhere that shows how fueling changes in a Bleed versus Primary needle jet.  Basically at the same throttle openings, a primary type will get progressively richer than a bleed type as revs increase.  That makes them great for 2 strokes that need more unburned fuel to keep them cool when run hard.

That same books showed the effect of air jets on fueling with bleed types and height of fuel shroud on primary types.  I should probably dig out those scans and post them somewhere.

a 2.5 should be about right but with the 28 a 3.0 would not scare me and might be better at cruising

they only make bleed type jet needles in very small sizes so i dont bother with them a lot as i am above in size most of the time

tell me what you have in it or better give me a quick call and we can figure it out and i can tell you how to do the sync

Coo, that's the pictures I was looking for last night. They are from a 1974 Suzuki carb manual.
There's one on eBay but way overpriced
https://www.ebay.com/itm/Suzuki-Carb-Carburetor-Shop-Service-Repair-Manual-9-74/140663475336?hash=item20c0324c88:g:K~UAAOSwkNZUar9C&vxp=mtr
(I think I paid around $12~$15.00 for mine15~20 yrs ago)
The main reason to have a smaller cutaway is to help prevent major 'flat spot' if throttle is opened too fast at slow speed. The best emulsion tubes I've ever had in XS650 (or 800) were a pair I made with a higher discharge height (only by 1~2mm, I forget, it was a while ago) Doing the cross drilling in brass was a 'challenge' to say the least which is why I aven't made any more

What size bleed style did you end up with? In my (limited) experience, you usually have to go a lot bigger on the needle jet when you swap from primary to bleed. Often a full letter up, or more.

It took me a minute to dig it up, as I couldn't remember if it was the 3RM CB360 or Kanticoy's Gretta.  On Gretta, Kanticoy did it similarly, but he drilled the valve cover at all the journals and used a rail to feed the oil.  He may be using a pump and reservoir, but I can't remember.  I do know he's using an external oil cooler.

It really isn't needed plus many of the tiny pumps are not rated above 150f~175f and you WILL be feeding it oil around 200f~250f (it isn't really cost effective for high temp pump or it needs too many amps to get decent flow)
 Use good oil, semi or full synthetic and do oil mods I've listed multiple times.
Use either 10W/40 or 5W/40 full synthetic JASO Spec oil
DO NOT USE 20W/50 - EVER cam bearings can seize in as little as 50 miles at highway speeds (70mph+)
Gun drill cam, open oil feed 'jets' modify oil transfer piece, good for sustained 11,000+rpm - 115mph

I've stalked your username across multiple sites for years while building my 360 - I did all the things you talked about aside from gun drilling the cam (don't have the equipment for that) last year the bike caught fire (while I was riding, lithium battery exploded under my ass) and it was all I could do to fix her and keep riding through the summer. Bike is now torn down and I am doing the 378 with gs850 pistons, and have since been stalking everyone else who so much as mentions such a mod, thus, I am now here

Bought a stock set of carbs modified by PJ from a gracious fellow member.  We'll see how it does.  I never really felt like the Mikunis were right. 

PJ, I seem to remember you talking about your modified stock carbs on a (yours?) 378 in another thread.  I hope I'm right about that.

In my opinion modified stock are way superior for road use (and not just because I modify them) I've tried Mikuni's several times but just can't get them to work as well on an engine that needs to pull from idle to 11,000 rpm. Using 26mm works but acceleration from 7k is slower than with 30's,(but then you lose bottom end)  32's are just too big until you have a 13,000rpm motor that doesn't go below 6K. The main advantage of the CV is it doesn't care what you think you want and gives you what you need

i would put a set of baby 28s up against any 360 with cvs

either on the road or on the dyno better horsepower and torque if tuned properly

Not across the entire range plus you have to be a lot more careful opening throttle or you will get flat spots when air isn't moving fast enough to pick up fuel.
It's an incredibly well known phenomena.(since at least 1950's)
Mikuni's will work lot better on four stroke with much smaller cut-away, 2.5 doesn't give enough air velocity when throttle is opened quick from idle so crazy rich 'primary choke' is used. Two strokes can mix fuel and air in crankcase but four-stroke doesn't have volume or time to do the same so you use a smaller carb bore (26mm works better than 28 in most cases) The Kei-Hin 'oval bore' carbs work better as they keep velocity higher, inverted pear shape would probably be even better but need more work on needle and needle jet, air passages, etc.
Because of the issue I've just had with JBM diaphragms, I'll probably be returning to Mikuni VM tinkering after I get another 4 sets of CV carbs done.
Even then I will still recommend CV over VM on 360 or 378.
 If I can't get them to run at least as well as a stock 360 I'll just stick with stock CV's and put Mikuni's back on the shelf for another 5~10 yrs.  Basically, the VM is too crude even if it is simpler to have only pilot and main jets. 3 jet Kei-Hin can control mixture more accurately even if it is a PITA without stock airbox
32mm VM,s worked great on my XS650/800 after I made new emulsion tubes and bought about $100.00 wort of different main and pilot jets, but, the stock CV carbs on XS 650 are weird and horrible so it was worth the hassle
 As you pointed out several months ago, CX has hig compression and heavy flywheels, you can make them  'spit back' real easy but also, when they are wound up the weight keeps them turning over.

Messing with timing, I thought I’d show off my favorite tool for static timing. It’s a voltage tester that comes with a threaded cap. The cap shares the same thread pattern as the points cover screw. Makes for an easy time...

Well isn't that just neater than shit. 
Will it plug into a Fluke? Where did you find it?

I found the 4 headers make a perfect meter bench when checking static time.

I think I got it from a BMW parts house, or eBay.  This one is the Hahn + Kolb version.

Betting I know a really good dude who could turn a few of those out to fit Fluke meter leads. 
You know, to pass out to his buddies.   ;)

I guess I'm not getting why you would want to.  I bought this for my tail bag, for testing when out on the road or trails.  It has a sharp tip that you can poke into insulation and the light comes on to tell you if you have power.  The yellow wire is your negative.  Plugging into a Fluke seems redundant. It already has  feature to tell you if there's voltage.

Probably just likes the idea of a screw in fitting for ground side? It could be handy when troubleshooting as well. Alligator clip often 'falls off' while your moving around

Yea the copper negative part looks to thread into hole.  If it just had a female end i could plug my meter lead into it and not mess w clip jumpers.

Ill get a pic when I get to work on Monday.  As my home fluke has cheapy leads that dont actually come apart to swap out the ends. like my good leads do.

I still don't understand why you would want this to plug into a Fluke or any electronic meter.  This is nothing more than a +/- make the light go on kind of thing.  It tests a line to confirm power.  That's why it works for static timing.

We have an electronics and general 'junk' shop down here,  (Skycraft) It's dead easy to make whatever leads you want. (gold plated contacts with silver plated copper wire, silicon insulation, etc) The ends are standard 'banana' plugs, the screw in part is easy to make with whatever thread you want Silver has best conductivity but copper comes second, both oxidise though. If you need specific threaded ends let me know. Copper is pretty horrid to machine but not impossible. I may make some for myself with 5mm and 6mm thread as it will be a lot more convenient when checking things, took way longer than it should have to re-set timing on the T305 Friday - 500 mile service/check over.  I wish I had thought of making screw in leads 30+ yrs ago when I was doing this full time  ::)

I have one of those............and a Fluke.

Me too.  I get having a lead that screws in, though.  I was confused why get this thing to plug into the Fluke since it doesn't do anything the Fluke can do better.  You can get leads with a terminal connector already.  They also have leads that fit into bullet connectors.

My meter at work has the bullet style leads w ends that can be swapped out for different applications.  I just need a cool copper one w the threads on it that would plug into the leads.  Thats what I thought you had, something similar.  As I didn't notice the little light in it.

I really like the build. I just  bought a cb360 from a guy at work. The backroad/forest service road theme is where I was leaning.  Your fab skills are amazing, mine will not be quite as custom!

Thanks, man. I just sold this one at Mid-O. It was a fun scoot.
