Title: New DTT member 360T build
Post by: kagraves on Jul 26, 2013, 02:05:05
Hey everyone, I am new to the motorcycle forum and wanted to let people see my build and to get some advice.

I just finished rebuilding my stepfathers 1977 CB750K and sold it to buy my first bike. Before the 750 I had no knowledge of motorcycle mechanics but did a complete engine teardown to solve a seized piston problem. got the bike running not perfect but sold it as a project for a very fair price, probably should have been asking more but I got hasty. purchased my bike a 1976 Honda CB360T the morning that the 750 was being picked up.

I purchased the bike not running (only thing I can afford and then I could tinker with it). the bike is in great shape has 9,xxx miles and very little rust (only under fenders and a little pitting on wheels). the 750 had 45,xxx miles and quite a bit of rust. the bike has been sitting since 07' in the sellers garage under a cover.

I tried some gas and a new battery but it wouldn't start, :o SHOCKER!

took the carbs apart and found one carb completely dry and the other had a damaged float valve. the fuel line was gummed up in the dry carb and ordering new float valves.

tank is a little dusty inside (light rust dust??) comes off when i wiped it. I plan on cleaning out with baking soda and vinegar heard that worked well for others. and take the petcock apart to clean out. and get clear fuel lines and inline filters to keep deposits out of carbs.

Still need to figure out why it won't run, but one thing at a time

Just got the float valves in the mail today and installed them.

bought 3 gallons of Vinegar to fill the tank to remove the rust. (worked ok, not great)

hooked up the carbs and tank (after flushing out) filled with some gas and connected a battery. 10 kicks and it fires! lots of black smoke and it dies :'( . set choke to half open kick twice and it idles at 2k. I dont have the airboxes on it yet so ik it will run lean with choke off.

ran it through all the gears to make sure it'll shift all 6+N work

need to go through more before I let it run more.

tried to adjust the cam chain tensioner to have it readjust backed off the locknut and it didn't move at all i loosened and then tightened the adjustment screw and still no noticeable movement. kept it loose and turned the engine over a couple times no change so i put the adjuster screw semi tight and locked it down not sure what to do/did wrong. I had the tensioner on my CB750 come loose and the engine ate the chain :-[ don't want that to happen to this one.

There won't be much (or possibly any) noticeable movement when adjusting the tensioner.  All that bolt and locknut combo do is release the tension on a bolt holding a spring.  The spring expands as much as it can and then you tighten it back up.

ok so i bought new fuel lines and filters to put on the bike because the tank isn't in perfect shape, but when i took the fuel lines off and drained the carbs this is what i got

(http://i39.tinypic.com/2lurs6q.jpg)
(http://i40.tinypic.com/5cit10.jpg)

its redish and settles below the gas, its almost the consistency of jelly in the carb but more of a liquid in the rest of the gas.

CAN ANYONE HELP ME FIGURE OUT WHATS WRONG!!

its obviously clogging my carbs up and its not normal

after cleaning the tank with vinegar i rinsed it out with gas and carb cleaner a few times. then filled it back up with gas. not sure what i should do about possible rust i'll try and get a pic from the interior of the tank.

the thing is the reddish stuff didn't come out of the tank when i drained it just the carbs and old fuel lines.

That tank is rusty as hell. Soak again in vinegar, with some screws or something to shake around every so often, leave it for a day, strain the vinegar, do it again, etc. Rinse with water and baking soda, coat with oil, fill with gas. New lines and inline filters.

so after i clean it all out as best as i can what keeps it from rusting up again?
Title: Re: New DTT member 360T build
Post by: Sonreir on Aug 06, 2013, 17:24:44
Keeping fuel in it.

You can also use a sealant such as Redkote or Por-15, but stay away from Kreem.

Post by: kagraves on Aug 07, 2013, 12:28:06
im redoing the rust removal with vinegar, i poured a gallon into the tank and a few handfuls of aquarium gravel to scrape out the sediment and rust. i heard that nuts and bolts can cause more damage to the tank putting scratches throughout, found that aquarium gravel is more gentle. i plan on letting it soak for 24 hours with vigorous shaking every so often to break more rust off.
thinking of redoing that process 2 or 3 times with fresh vinegar each time and see how it turns out. Im thinking about doing a tank sealer either REDKOTE or POR-15 has anyone used either before and are there tips or benefits for them.

ill take pictures of what comes out of the tank and the inside after each change

He just means motor oil. It will skim-coat the tank and prohibit it from flash rusting.

I just spent the last week of my life cleaning out my 360 tank using the vinegar and screw method. It's a terrible mess and a pain in the ass but it works. I had flaking Kreem with a layer of rust underneath and it took 3 rounds of fresh vinegar and rinsing with water to get it all out. I did my final rinse with isopropyl alcohol to avoid flash rusting and it looks pretty good. I can still see a few spots where the Kreem is still attached and I'm hoping it doesn't come off and clog my petcock and filters.

Post by: mrodub on Aug 08, 2013, 12:13:41
I may try coating with oil but I'm not sure if I need to now that it's completely dry and rust free (at the moment). The oil surely won't be a long term solution once you add gas to the tank. Does anyone else have any other CHEAP solutions beside keeping the tank full?

just picked a grabber tool up like this at lowes came in a combo pack with a telescoping maget pickup tool for $3. thought it would work nice to pick up the last few rocks in the tank when rinsing it out. you might be able to use it to rip the old liner off though.

ok so after a few days of vinegar and rocks and a lot of shaking i think the tank looks pretty good

(http://i42.tinypic.com/e9tbud.jpg)


the tanks seams to be flash rusting almost instantly after flushing out with baking soda and lots of water. i poured about 4 cups of oil in the tank to give a nice heavy coat to prevent further rust. ill most likely be doing the por-15 tank liner possibly over the winter while im home for break.

 You dont need no liner.  that thing looks great.  If she aint leaking...Dont fix it.     I filled mine w gravel, tossed it in the clothes dryer (NO HEAT) for an hour.  Been running it for 3 years.  Right now, Mine looks about like your before pic minus the loose crap.  threw the crap ass inline filters in the trash after first year.  Nothing but the screens on the tap the past 2 years.  Hasnt clogged at all.

good to hear trek, how do you replace the filters on the petcock? mines kinda gummed up and id like to atleast get it out to clean it but i dont want to break it. i have the inline filters but id rather not use them to keep the lines simpler.

Post by: trek97 on Aug 11, 2013, 07:03:28
The original stock petcock has the screen on the reserve tube.  it was torn so I got a new petcock from ebay.  it has a nice nylon screen on the reserve tube.  Also, just like the stock one.  it has the brass screen inside the cleanout bowl on the bottom of the petcock.

 I pulled one of the little magnets out of an old hard drive.  snapped it in half and placed it in the petcock bowl.  To help catch particles.  It works great.  I remember I cleaned it off once since I placed it in there.  Probably due for another cleaning now...whatever.

The new petcock was like $25 and its nice.  I was pleasantly surprised.  I half expected it to be chromed plastic.  Its not.

Some guys place a second screen on the primary tube inside the tank.  You should be able to get a small piece of brass fine filter screen at any hardware store.  I havent done this yet.

Next on my to do list is to work on the brakes they both stick some and I do not want a lockup on the first test ride ( well... Ever actually!) I also need/want to check and clean the oil slinger/filter but have had some trouble finding the proper way to do it and heard if done wrong you can break it or have leaking issues.

Any help with the oil slinger would be appreciated
Title: Re: New DTT member 360T build
Post by: trek97 on Aug 11, 2013, 07:58:39
I have thought about putting the magnets in the carb bowls, but got to thinking the pins in the floats are steel.  so they may stick to that and cause issues.

Yes.  I believe my bike spent alot of its life on gravel roads cause it was packed,  kinda like dry concrete mix, mixed w oil.  taking the cover off is no big deal.  you can do it on the bike.  Just get a nice craftsman impact screw driver.   ring pliers and if you want to remove the cup from the shaft you need one of those spanner socket things.  When I did  mine I was pissed off and impatient.  I made a spanner from a socket w the cut off saw and grinder.  It sucked but it worked.  The store bought spanners are cheap enough and look nice.  You could get it pretty darn clean without actually removing the cup from the shaft though.  If you just take your time.  and get inventive making little picks and scrapers from stuff you have laying around the shop.  And a good flashlight.

Heres the post I made about it...just scroll down about halfway or so.

Cleaned the bike out and back together put the clear fuel lines on with the filters put the air boxes ad filters on. Filled with gas and the fuel doesn't flow. I took the petcock off and cleaned it all out. Fuel trickles but not how it should. I think the filters are causing air to cause back pressure :/ so I took the filters off and it take gas better but not perfect. Tried to kick it over and it will only run on the right cyl sounds rough I think the cam chain is loose xp I hate these cam adjusters there's just no confirmation that its adjusted well. Ugh...

Yes it was 13/16, and by some miracle it worked.  a store bought would be much better though.

Dont let yourself get flustered...and believe me I know its difficult not to.

With the filters out of the system do the fuel lines eventually fill the carb bowls?

 If you have adjusted the tensioners (hot engine) before.  I am sure they are fine.
 
Did you adjust the valves, (cold engine)?  I just did my valves the other day.  First time after last falls rebuild.  you may be hearing them slap a little. 
after setting valves.  Intake .002, you really shouldnt be able to push the .002 feeler back in.  I set em w the .002 then try, it wont go.  BUT I can get the .0015 to slip in there...It can be a bitch but she will slip in.
 
on the exhaust, after setting with .003.  It wont go back in.  but w some effort I can get the .002 to slip in.

The engine must be rotated on proper t.d.c. exactly.  I keep the wrench on the rotor bolt and use zip ties on the foot peg bracket to hold it there.  TDC exactly. 

When the nut is loosened, and the proper feeler in there.  I roll the screw driver with my finger tips.  Lightly, tightening.  until the tappet bottoms on the gauge.  Then I roll off a bit, until the feeler can slip around a bit.  Then gently tighten again, back a forth.  Looking at the screw slot, for consistency, Just until I am satisfied that I have it a .002 with out pinching the gauge or being too wide.  Then while holding the screwdriver where I want it, and tighten the nut fully tight.  Slip the guage out, feeling that it doesnt have too much pinching drag.  and try to push it back in.  If I cant get it started I try the next smaller size.  The .0015.  I can get it to slip in.  I know I have em as close as I am going to get em.

Didn't do the valves yet because I had it running and it sounded good, if it ain't broke don't fix it. The carbs get gas but very slow on cyl 1 the battery is dead but i was able to kick start if, maybe not good enough. so I'm going to hook it to my car and try again, maybe just not enough power when it starts running to get both sides to fire. I did just adjust the cam chain hot it was cold but I'm going to redo it cold again and make sure all the valve tappets are loose, I don't do this before so I might have been on the wrong stroke. On ce I get to ride it I'm going to do a hot adjustment.
Title: Re: New DTT member 360T build
Post by: trek97 on Aug 15, 2013, 08:02:10
adjust valves = cold
cam chain, points/timing, air/fuel needles = hot

any time you adj cam chain you need to re-check timing.

Ok update, got the bike to run its the battery problem. It was just too dead to keep a current flow once the bike was started. I'm not purchasing a battery because its just going to sit from next week till late spring and will die :( . Ill do all the adjustments once I can get her running and hot, that way I can check how it responds to driving conditions.

Played with the bike today and it's acting weird. I can get it started but it's way under powered electrically. But when I turn on all the lights and hit the brake to turn the brake light on the bike powers up. It lets me rev it and runs pretty smooth. Let off on any light and it goes rough and can't rev and dies. Not sure what's up. Electrical problem?!? I didn't play around with anything though.

On a side note, how can I check the charging power coming from the bike alone??
Title: Re: New DTT member 360T build
Post by: Sonreir on Aug 16, 2013, 01:28:34
First check for charging is to measure voltage across the battery terminals with the bike at idle (assuming you can get it to idle).  Should be about 12.5V.  Rev up to 4000 RPM and you should be seeing close to 14V at that point.  If significantly less (like under 13, still) then you have charging problems.  If over 14V and getting closer to 15V, you've got a regulator issue.

Now we are getting to the root of it...you used the "G" word.  Loose the money pit, Oops I mean girlfriend .  and you will more than double your bike time.  drop a few bucks at the massage parlor every couple weeks.  And you will have more freed up cash to put towards the bike and beer w the bros.  Still having plenty of time for studies.

everybody wins.  Priorities man. 

I am the happiest married guy I have ever met.  I dont recommend it to anyone.

It is idling fast, However she sounds every bit as good as she looks.  Keep up the good work.  Before you know it you and her will be having a blast terrorizing the streets of campus.  Ive got you bookmarked.  So, when ever you get the chance, even just to pop in and say "hi" add to this post, I will be lookin for ya. 
Now, go get your ass off to class and make us proud.

I'm back!

First thing I had to do was pull the bike out of storage and hear her run. Still don't have a battery but with jumper cables off the car battery got her to start with the electric starter. Needed to be turned over for about 10 seconds before it would fire on both cylinders. tried the kick start and got it to turn over and start. From before storage I had posted a video and was told that the idle was too high, I warmed the bike up and with no choke was able to drop idle to 1,100-1,200 stable but it seams to bog down when I give it throttle. Probably due to all the fuel stabilizer in the gas from storage. I plan on doing a carb sync when I can get a hold of a gauge.

The problem so far is the kickstarter doesn't catch most of the time and I have to just keep playing with it for 10+ seconds before the gear catches again. Wondering if anyone else has had this problem / know of a solution for it? I don't remember it being this bad before storage.
Title: Re: New DTT member 360T build
Post by: trek97 on May 15, 2014, 07:19:02
Welcome back dude!
Yup, get some fresh fuel in her.  And see if she acts better, After she sits parked for a long time, and open the tap, need to give her a minute to fill the bowls completely before hitting the key.  Carbs were probably dry from storage. 

double check the timing w a strobe light and ensure the advancer is working smoothly. 

Also, maybe the ratchet thingy on the kicker is just sticky from sitting.

Ugh so haven't had much time to play with the bike as I've been working long hours everyday. I go into the garage about a week ago and find it laying on its side in the center of the floor and wreaking of fuel. Apparently the fuel line came off and allowed the whole gas tank to empty (forgot to close the tap) on the floor which destroyed the pavement and allowed the center-stand to sink in and then tip... FML. I picked it up can cleaned up the mess no damage done to the bike luckily.

I purchased some fuel line clamps and a battery for the bike and have her all together now. Got her running off her own power and she runs alright I think the carbs might need to be re-cleaned after sitting all winter because the idle isn't perfect.

Today i got my permit... finally I know, and am looking into insurance plans and getting her registered soon. i did notice that the turn signals are not blinking, only staying illuminated, so ill have to check into that before registration and inspection.

She's idling at 1,100 with just a few hiccups. I'll try to get a video on later.

And now it doesn't run on both cylinders and I only have a week extension on my inspection. Plan on checking for fuel and spark and going to pick up some new plugs because I'm guessing it's fouled at this point.
Title: Re: New DTT member 360T build

Make sure the petcock is flowing freely, the gas tank is full, and that both carbs are getting fuel.

Post by: kagraves on Jun 28, 2014, 14:08:10
Cleaned the tank and petcock, therr is fuel flowing to the carbs. new plugs, have spark but still running on the right cylinder only. Went over timing and point gaps and everything looks to be correct.

Its 90į out and I'm in the sun getting frustrated

I should take the carbs apart but I don't have time before going to work, maybe tonight.

Any thoughts?

Have you checked compression?  Checked valve tappet gaps? Does it run on one cylinder at idle and also when you rev to higher rpms?
Title: Re: New DTT member 360T build
Post by: kagraves on Jun 29, 2014, 21:36:27
Got her running, between re adjusting the points and timing, putting more fuel in the tank so it could run on ON not RESERVE, plugs are nice and golden from running here and bought a bunch to do plug chops and adjust the carbs to the best of my ability.

But I need to find time this week to get her inspected.  :o

Virgin ride is under my belt!

Inspection done all the stickers in the right place and the plate is on. Went for a nice short ride to and from the Service Shop < 40 mph, illegally ie. I'm riding on a permit...  ::) all went well.

The right exhaust is blowing a little smoke and there is a pulsating feeling around 4k rpm so ill have to look into that. and some noises that may or may not be normal as far as drive and cam chain go. i was used to being a passenger on the CB750k, so it was a bit of a more powerful and smoother pull

For now I'm ecstatic and my adrenaline is pumping. cant wait to get her tuned up perfect.

ps. I only stalled it a couple times... gotta start somewhere!
Title: Re: New DTT member 360T build

Just bought a carburetor synchronizer online for cheap

Parts included in the Kit:

1 x Bracket
2 x 2 & 3/4" Gauges
2 x Hoses 4mm(.I.D)x7mm(O.D.)x75cm (L)
2 x plastic Valves 5.5mm(O.D.)
1 x 180mm(M5xP0.8 ) Brass Extension
1 x 65mm(M5xP0.8 ) Brass Extension

I'm just wondering if these are going to be able to connect to my carbs or not, kinda aiming this towards pj cause you said you had a set of vacuum adapters available.

Post by: kagraves on Jul 22, 2014, 22:56:21
got the adapters a while back but i was on vacation, ill be doing the tuneup later this week. the battery is dead from sitting for about 2.5 - 3 weeks without being ran, has anyone else had a new battery die so quick (acid refill type).

I got my bar end mirrors in the mail and try to install them but come to find out there is a solid plug inside both bar ends... didn't know about this setback...

(http://i58.tinypic.com/156a1j6.jpg)

and the bar end mirros only go in about .5 inch and need to go about a full 2 inches

(http://i62.tinypic.com/34ealgh.jpg)

not quite sure what to do, I've done a little googling and some people have drilled and tapped the solid bit and just screwed into it with some loc-tite...
Title: Re: New DTT member 360T build
Post by: kagraves on Jul 25, 2014, 12:23:41
So the smoking issue was excess fuel, took the carbs apart and the slow jet was just sitting in the bowl like it just wasn't screwed in tight. bike runs alright but needs the carbs synced, i have the gauges but has anyone done the adjustment without the motion pro tool?

My battery is not holding a charge, I put the float charger on it and get it to 12v. Button everything up give the bike a kick it starts and runs fine. As soon as I turn it off or I stall out I have no power. Luckily with about 10 kicks i can get her going again. the charging system was working when i got the battery, giving me over 13v but ill have to recheck that now.
Title: Re: New DTT member 360T build
Post by: kagraves on Jul 25, 2014, 12:25:17
I also bought a tap from homedepot for $5 so i will have the bar end mirrors attached once I drill and tap the bars.
Title: Re: New DTT member 360T build
Post by: kagraves on Jul 31, 2014, 12:56:09
Solved the electrical issue by keeping the bike on the float charger for 24 hours and now its good and strong, even the electric starter works again, (must not have been getting enough power). I currently have the float charger hooked up to the battery but as I do not trust Harbor Freight electronics; I have a timer attached to the float charger so it only runs for a maximum of 2 hours twice a day.

Got the bar end mirrors on and only running into a few snags along the way with drilling and taping the stock in the bars, broke the drill bit in the bar. Luckily I was able to get the bit out with some careful fidgeting for 10 min. had to use another drill bit, unfortunately the closest I had was 1/64 smaller which usually wouldnt be that bad but it made the taping much more difficult. The taping process I took nice and slow because I did not want to have the tap snap off in the bar due to the slightly smaller hole. Luckily the bolt for the bar ends is a 8x1.25 bolt and the hole in the bar is over 1.5" deep so there's plenty of beef to hold it in snug. I used some anti-seize so I can take them off in the future if need be.

Took the bike out for a spin and the improvement on visibility is incredible! I can see everything now and there's not too much distortion when it comes to judging distance, nothing my usual head checks don't cover. there is vibration but still not bad enough to not show cars coming up on you.

Attached are some pictures with where the bike stands now and a quick photo of the shop (garage).

It's helpful to not be staring at my arms the whole time and I can see whats about 5 ft behind me (my car is about 25 ft back). it does take some getting used to because the depth of field is a little distorted but the head checks verify where cars are before lane changes.

Drilling and tapping the weights is a good idea, the stock fittings are pretty crap and mirrors work out of bars
Title: Re: New DTT member 360T build
Post by: kagraves on Jun 26, 2015, 15:20:36
So its been quite a while but I'm back and here's an update on whats been going on. As soon as I returned home from college i took my road test and now have my license. Finally got around to syncing the carbs, setting the idle mixture levels and a nice cleanup of the carbs. it now idles down to 1k rpm although I tend to keep it around 1,500 when riding.

I replaced the stock bars with some lower  euro/super sport style bars, wanted some more forward lean and lower control without getting too aggressive and ruining ride-ability. Had to drill out the bars to run the stock wiring internally and without to much trouble was able to get them fished through. put the bar end mirrors back on with the expanding clamps they came with cause the new bars didn't have weights inside to drill and tap again. the vibration on the road is gone now in the mirrors which is a much appreciated improvement.

So far this summer past month and a half I have put 800+ miles on the road, trying to enjoy every free moment and get on the bike. the new riding position is great and keeps stress of my back and arms during longer rides.

beginning of the summer

some things i want to go are to have my turn signals act at amber running lights, either on when on low beam, on a separate switch, or on whenever the lights are on. just wanting to get a little bit more visibility at night. I'm not sure how to do this because i believe the 360's were all 2 wire lights and to have a running light you need a 3 wire outlet. so any advice would be greatly appreciated.

also as I ride along and come to a stop the engine is idling around 2k so i adjust it back to around 1,500. but as i go it keeps getting up to 2k and once again I readjust, it seems like I just keep adjusting down further and further on ling rides and was wondering of this is normal???

also i just replaced my front brake pads because it sounded like a subway train was trying to stop whenever I applied the front brake, now its as quiet at a mouse!
Title: Re: New DTT member 360T build
Post by: frogman on Jun 26, 2015, 16:45:20
Front turn signals should have running lights in them. Get a set of front signals and install them on the rear and run wires from the tail light to the low beam feed in the lights.

For the idle, you should be setting the Idle and the idle mixture when the bike is warmed up really well. If you set it cold it will do exactly what you say its doing. Can also be that your not getting the throttle back down to closed, roll forward on the throttle when it does it and see if the idle goes back down.

Otherwise you might have an air leak that shows up when the bike gets warm. Cracks in the intake boots will do that as the bikes warm up.
Title: Re: New DTT member 360T build
Post by: kagraves on Jun 27, 2015, 15:15:51
Thanks for the reply frogman,

Opened the headlight bucket and found both running light wires were disconnected, PO must not have liked them or something. I plugged them into a open connector so now as long as the key is on the running lights are on, high or low beam, I'll try them out at night but may switch to a different power leed if I find the running lights to be obtrusive when having high beam on back roads.

I was thinking you were saying to just get the same bulbs as the front to put in the back but when I got home realized that it's a different socket,  :o can you just change the internals of the rear signals or is it better to replace the whole unit??? I want to keep oem style lights.

My carb boots do have very tiny hairline cracks doesn't seem to affect performance besides the higher idle when she gets to full temp. If I find a set for not a lot of $ I'll be more inclined to replace them.

Purchased a set of front turn signals from the selling thread, so hopefully within a week I'll have them to install.

As far as the polishing goes I was using this Ryobi buffing kit from Home Depot that was $10, just went out to buy a larger diameter wheel and found a set of three with different types of wheels to speed the polishing process. The kit comes with a 1/4 inch drill bit attachment, I'm just using some washers to hold the bit attachment to the buffing wheels. I'm using a Black and Decker corded drill that gives a decent rpm. I have a bench grinder that I put the buffing pad on originally but the grinder is very old and I can practically stop it with my finger...

So I have the new turn signals for the swap to achieve running/signal lights in the rear as the front does. with some mock up wiring I'm having trouble to get them to work with different wiring combinations. I can get just turn signal, or just running but not both the closest i got was when i hooked up to the headlight bucket but I can't get both filaments to work.

Title: Re: New DTT member 360T build
Post by: kagraves on Jul 09, 2015, 22:01:51
helps to hook the lights to a ground...   :o

I now have running lights front and rear. The front is ON with low-beam and OFF with high-beam, and the rear is on all the time. I had a issue with blowing a fuse when having the front and rear on the same circuit, so I ran a wire to the headlight bucket and plugged into an open connector.

Although now my electric starter isn't working, maybe because I've had the lights on without the bike on for quite a while to test things to the point where the flasher stopped working. Battery drained too far, so I kickstarted it. 1st kick and started right up, held it at 3k and the signals started to work. I'll be leaving it on the tender overnight to charge back up because its raining here so no riding tonight.

Also going to check the front bucket to make sure I didn't pull a wire out (for the starter in particular)
Title: Re: New DTT member 360T build
Post by: frogman on Jul 10, 2015, 09:05:56
Now the only thing about running rear lights like that is that it might drain the battery if your charging system is not good enough to keep up while you are riding. Time will tell with that, but its my belief you should be OK.

Might just have to spend more time above 2k rpm, might have to go to LED bulbs.
Title: Re: New DTT member 360T build
Post by: crazypj on Jul 10, 2015, 16:37:44
Probably a good idea to switch to LED 'dual filament' bulbs
Running lights should be connected to the blue/white stripe and orange/white stripe and will need wires run to rear from front
Title: Re: New DTT member 360T build
Post by: MGD on Jul 10, 2015, 17:32:48
When switching over to LED's you will most likely need a flasher relay that handles LED's.

Otherwise your turn signals will flash at a higher rate with LED's.  Not really a huge problem.
Title: Re: New DTT member 360T build
Post by: kagraves on Jul 10, 2015, 23:18:42
Battery not able to handle them for city riding  :'( they just stopped flashing all together. Did just what you said crazypj. So I'll probably be looking into led bulbs, also thinking about upgrading the headlight at some point as I still have the sealed beam, any suggestions for either?
Title: Re: New DTT member 360T build
Post by: crazypj on Jul 13, 2015, 12:37:45
You need to make sure your keeping motor at 2,000rpm or more for battery to charge. If yur idling too much with indicators, running light, headlight, etc battery voltage can drop low enough to cause miss-fire or even cut out
I used a hole saw to cut through back of reflector, broke the bulb out and glued in a 35/35 H4 halogen bulb  ;)
One filament had burned out anyway so sealed beam wasn't any good (I like to have high and low beams working)
Pictures are in the 360 build/blog somewhere  ::)

Thanks pj, I understand the charging issue, just wish it wasn't a problem in stop and go traffic. I did a 400 mile trip yesterday with almost no time under 3500 rpm and had no problem. Never had a problem beyond the flashers just not flashing in the past (no misfires our stalling)

I saw your headlight modification, my headlight still works and I'm trying to keep all the stock parts in case I decide to go back to stock. How would you say the improvement is for the 35/35 H4?

So I tried it in the brake light cause I was planning on getting a led bulb for that too but wasn't sure if it was the same bulb at the time. The bulb works perfect in the Brake light below are the bulbs in white. I'm going to look for amber versions for my turn signals tomorrow I think autozone had them too.

The thought crossed my mind, the auto parts stores only have the single stage in amber so looks like I'll be ordering them online. I was thinking about doing all red on the back but then I'd want to change the lens color. I just can't win.

They do make red lenses, I've though about them myself.

That tail light fix tape you see at the auto parts store, the stuff that is clear and colored? LEDs shouldn't get HOT per say, get some of that and tape them suckers up the color you want them.

Update I had a welder try to fix my cracked fender, it lasted all of about 20 min and broke the weld. So I took an angle grinder and chopped the front half off, I'll get some picks of the turn out. In the process my speedo cable broke of the bottom connector at the wheel. FML...

Does anyone have one they are willing to part with, supposedly the 350, 360 abd 450 are the same cable...

Took a compression test the other day with my newly acquired harbor freight compression test kit. 105 psi left side and 110 psi right, put a tablespoon of oil in each and had an increase of 10 psi for both. Do my winter project will be installing new rings. And a valve lapping for safe measure. Everyone is apart I'll do a complete polishing of the cases and get get looking better than new.

Also need to get a headlight that accepts an H4 bulb that fits the stock bucket/new bucket with H4 bulb that is close to stock looking, and new carb seals cause I'm getting a bunch of gas deposits sound the bowls recently and ik the gaskets were in need of replacing sooner or later.

Harbor freight compression testers are known to be low reading on small engines. As long as the bike idles well and runs well and doesn't burn oil badly I would leave it alone. My 360 reads out at around those same numbers with my harbor freight gauge and runs just fine.

Just get a new speedo cable, they are available online for not much money, I think I paid 15$ delivered for the one on my bike.

So I'm having oil coming out of the breather hose and covering my rear tire I oil. I checked the breather gasket and it's in great shape. Took the side cover of to clean it out and do an oil change and it looks to be in great shape. Re filled with rotella diesel oil to the 1.5 lt that the manual states and the dip stick doesn't even touch oil. Had to add about another 1/4 lt to get it to register. I'm wondering if at some point the dipstick was switched and is shorter than stock making my bike to have to much oil and coming out the breather hose. Could someone with a stock CB360 measure the length of their dipstick (just the stick portion).

Any other thoughts from fellow 360 owners?

Also my rear tire is completely flat this morning. I need new tires anyway. Wondering if tubeless tires can be used on the stock rims or should I get tires and tubes.

And when I took the exhaust of realized it's been in two pieces since I've owned it. The coupler was broken off the muffler to the header. But brought it to a weld shop and had it fixed for $20.

360 uses 2.1 quarts.  Leaking rings could be building pressure in the crankcase.  Blowing the oil out.

I'M BACK!

Itís been a long time but I'm finally back at it. Last week I completely ripped the bike apart to get to the cause of my blowing oil issue, the lowish compression, poor fuel economy, and tires that were too dangerous to roll down the road. Started the rebuild with new rim strips, tubes, and a set of stock size Avon Roadriders. Ripped the engine down to replace the rings and found that both pistons had the top rings cracked through but no damage to the cylinder walls. Replaced the rings with a new set from commonmotor.com, cleaned all the carbon buildup off the pistons, valves and cylinder head and put it all back together with new gaskets. Gaped the valves and set the timing. Replace my broken carburetor float bowl gaskets and did a quick cleanup. Flushed the gas tank and installed new petcock seals. Got the bike all put back together and with a new battery.

Trying to start the bike and all im getting is loud pops from the exhaust but it wonít fire and turn over. Iíve been following the instructions from my Clymer manual and from some youtube videos. Any tips on troubleshooting my issues would be much appreciated.

So after troubleshooting the bike for a while I found out that my cam was installed with the rotor on the wrong stroke thus making my bike try to fire backwards. Also had the worst point gap so there was almost never a spark. Luckily it didn't for as it would have probably blown my carbs to bits.

It is back the right way now and running real good. Put 80 miles on it tonight.

The points cam on advancer mechanism is the only thing that can be placed 180 degrees 'out' There are plenty of images and instructions how it should be fitted (I know because I'm the only person who ever posted them)
It isn't possible to fit the cam 180 degrees 'out', it turns at half crankshaft speed so next revolution it will be 'right'

exhaust leak won't do much damage. Been riding around for three weeks right now, still got to weld it shut.
Inspect for black carbon deposit spots on the exhaust or areas close to it. In the neighbourhood of the hole you should see a black spot if you've driven it around for a while.
Title: Re: New DTT member 360T build
Post by: kagraves on Jun 26, 2016, 14:29:15
So the exhaust leak was old exhaust gaskets, I bought new ones and replaced them. The engine still seems to have a weird ticking going on. It's not the valve gaps or cam chain, so I've been playing with the timing and trying to do it dynamically. The timing at idle is spot on, but the advance marks aren't lining up till around 5500rmp if I I remember correctly.

I also noticed some smoke out of my left exhaust when I rev from idle, I don't think I ever checked my float heights and when I cleaned my carbs up so I may check the heights to make sure they are in spec. The left plug has always been a little richer than the right. I know people said the stock heights were wrong and had a better setting but I can't find that link for the adjustment.

I also replaced my gauge lights and idiot lights with the ba9 leds from superbrightled.com, they are a great upgrade and use a lot less power for my charging system. And I installed the h4 conversion headlight from common motor to help see where I'm going. https://www.superbrightleds.com/moreinfo/ba9s-ba7s/ba9s-led-bulb-1-led-ba9s-retrofit-classic-car-bulb/4/

Sounds pretty normal to me.
 Valves may be a little tiny bit loose but not too bad
Cam chain sounds fine
Setting left side can be difficult because magnets in generator and srings on right side valve are trying to turn motor further than TDCC
I use a 14mm box end on rotor bolt jammed onto footrest or gearchange, others use a socket and long bar onto floor or frame

Post by: kagraves on Jun 27, 2016, 14:25:07
So last night I checked the valves and did them so that there was a little more resistance on the feeler guage without going too tight, so I'll stop panicking about the valves.

Does anyone know if I should have the timing mark line up with the advance marks at any specific rpm?

And what do you guys recommend for float height settings? I've been seeing anything from 14-20mm, and I'm running all stock filters and exhaust. One plug tends to be more rich than the other so I'll start with adjusting to the level of the better side.

Thanks again everyone!
Title: Re: New DTT member 360T build
Post by: advCo on Jun 28, 2016, 00:20:40
I think mine are at 18mm on the 360. A good way to do valves is to set them using the feeler gauge 1 thou up from what you need, and set it a bit on the tight side. So if your intake calls for .002, set it at a fairly tight .003, check it again with the .002 and it should be good. Either way works but I thought this was an interesting method when I heard about it and it worked out for me the last time I did the valves.
Title: Re: New DTT member 360T build
Post by: crazypj on Jun 29, 2016, 02:54:43
I used to teach people the 'go-no go' method.
Use a 0.002" feeler for intake, it should slide in relatively easy.
Try a 0.003" feeler, it shouldn't go in at all
Use the 0.003" on exhaust, 0.004" won't go
Simple and more than accurate enough.
 Eventually you get 'the feel' and don't need go, no-go (although it's handy to check if you haven't done a valve adjust for a year or two)

so the bikes been running great for the past few weeks as my daily commuter and as my weekend warrior. but yesterday I noticed some popping from the right exhaust almost like its misfiring... and it seemed to be running a bit rich at idle. Got it home and today went to check the valve clearances and cam chain. They were good. started the bike up and its still popping and now, with the valve caps off I hear what sounds like somethings bouncing around the camchaft... and the engine is making a weird noise around 3.5 - 4k rmp. I'm scared to ride it or even rev it above 4k. any thoughts??

Advancer seemed to be all good, lock nuts were all snug with proper gaps. Took the cover off and everything seemed to be good, chain tensioners still intact and in proper position. All boots were snug even though I thought the bolts holding the cam gear was going to be the cause of the problems. Cleaned everything up and re installed it. I'll going to go over the point gaps tomorrow. And the valves even though they shouldn't be different. Going to re set the timing and then start her up to see if there's any change.

I hope so as I am taking the bike back to my alma mater on Sunday and will be teaching high schoolers about graphic and industrial design for the next 2 weeks. The 360 is still my only mode of transportation, which I love! don't get me wrong but she likes to act up every once and a while.

got the bike running, but the left cylinder it's not firing at all. I checked and have fuel and air but no spark. I have power at the points and they are gapped and timed correct. I'm checking the coils have 5ohms on primary, and 14k for secondary. I'm getting 12v from the plug wire and grounding on the engine. Tried new plus and the ones that were working on the right cylinder and still not getting spark.

Can't find any shorts in the wiring.don't know where to go from here.

I cooped the end of the wire and screwed the boot back on. Much better reading for checking the coil now. I have a parts guy near me that had a 360 in parts so I'm going to give him a call for some points.

Most Honda dealers can get you a good replacement set, if you are gonna replace them I wouldn't put used points on there as they may be worn as well. I think I paid $30-35 for points and condenser "ignition tune-up kit" at the dealer - and they had it in stock.

wondering what peoples experiences with the PAMCO ignitions are like. Found these for $190, although I'm not looking to put that money into the bike at the moment.

http://4into1.com/pamco-ignition-with-electronic-advance-honda-cb360-cl360-cj360t/

is it a noticeable difference for performance and reliability or more so that you can set it and forget it?
Title: Re: New DTT member 360T build
Post by: crazypj on Aug 02, 2016, 19:55:05
I don't have experience of the Pamco but he's been around a while, was originally on XS650 Garage if I remember right?
Anyway, I do have some experience of electronic ignition on CB360's.
It's a major upgrade and worth the cash
Bike starts easier and runs much better as long as if it stays in one piece.
In my opinion, the issue seems to be the CB360 heads run hotter than CB350 or XS650, probably because of unitary construction instead of separate cam carriers with gaskets (may not be much but it does make a difference)
I think Pete has been doing some tweaking to keep it reliable plus, I think he has a settable rev limiter? (been years since I looked at specifications)
Dyna doesn't seem able to last more than a few thousand miles, even with slots cut in the outer cover to help it stay cool (you probably know heat is the major issue with electronics, makes them 'age' real fast then break)
when you start getting over 200f (normal for 360) it's only a matter of time before it breaks.
The Pamco has separate 'blue box' which can be mounted somewhere way cooler,
 If the hall effect sensors fail they are relatively easy and cheap(ish) to swap out with new ones but I think they may be upgraded to military/NASA/aircraft spec now? (probably 10~20 times the price but still less than $10.00 each  ;D )

Got the new points in and the bike was running great.

Until I was heading to work yesterday and the bike started to act up and make a lot of noise. Got to work and parked it. Checked it out when I got off work thinking it was the valves/cam chain. Nothing helped. Got a friend to trailer it back to my place where I took it apart. come to find the bolts for the chain tensioner holder backed out, one had come off and was crushed. Further searching for damage found this

So took the bike out with my brother and friend for a nice 100 mile drive around the fingerlakes. Nearing the second half of the trip I noticed my speedometer acting up. Was reading about 10mph high. Then it kept getting worse till it was reading the ton at around 60mph. So has anyone had an issue with their speedometer? It has a brand new cable last season and never had an issue apart from reading the stock 5mph faster.

Also about 20 miles from home she shit the bed, wouldn't rev above 4k rpm and had no power what to speak of. Every time I stopped I had to run with the bike till she would be able to go without bogging down. I pulled the plug leads to see if I wasn't firing on 1 cyl and it would get worse so I don't think it's a firing issue. Even with the clutch pulled I wouldn't be able to rev her up. I have not had a chance to take a look at her since limping home. :(

41 years old and showing signs of age...

Fun trip, sucks about the trouble. 
Maybe a torn diaphragm or ignition (timing/hot coil) related.

Spot on with the torn diaphragm trek, the left has about a 1 inch rip. I've looked into oem replacements but cheapest was $140 for a set of 2. I decided to go with the jbm industries modification and replacement. Ever ended around a little bit since installing replacement but find that between 0 and a half throttle I get lots of stumbling and low power. I saw on a post  for jbm diaphragms on the 360 that you might need to drill out the holes on the slides can anyone vouch for this? and are there other ways to adjust without permantly drilling a larger hole in the slides. I have no issues above half throttle especially above 5k rmp

Send a message to CrazyPJ, he knows everything about these carbs.

I believe it was pj that posted the drilling mod

PJ and I worked on drilling slides together to no good result.  Dont drill the slides. 
I dont know if he continued w the work alone, after I gave up. 
its possible his post just may be "theoretical" thinking out loud.

You can continue working w the JBMs.  But sorry to say my JBMs went straight into the trash.  My bike wouldnt even try to run with them.  Anything past 2500rpm was shit.  I ended up w the new Honda slides, daphragms and springs, kit #7 from phish, I believe.  And it really paid off w a huge improvement.  Im not gonna tell you it was a total "plug and play" type situation as my carbs are HEAVILY modified.  the Honda slides may or may not help you as much as they did me.

Glad I could help finding the torn diaphragm...Sucks you found a torn diaphragm.

Thanks trek and it only boss from 2500-4k rpm above it runs like a champ and it idles perfect. I can get it down to 800 and up to redline.

The JBM diaphragms are softer than stock, and also removing those small plastic keepers makes the slides lighter. Because of that they let the slides rise early, I had the same issues with them in mine they went back in the box and I put stock back on.

Best option is to get factory ones. I know they are pricey but you won't pull near as much hair out with them as you will the JBms.  I guess if you had a stock set and weighed them and compared it to the modified ones you'd have something to go on, at least as far as maybe being able to add weight to them.

Yep, it was me who posted about drilling slide holes. I would have to look it up but I think it needs 3.8mm holes? (probably posted somewhere?)
Trek, I was looking through some old pics the other night and found some red carbs  ;)
In my experience, the original JBM were stiffer than originals but the new ones are just about as good as original Honda (when slides are drilled)

Drilled to 3.8mm (actually drilled to .149in) as the set I have access to was SAE. Took the bike out and it rips through all rpm and throttle position ranges! Thanks pj you have one again added to my progress!

LOL, I screwed up a few slides working on correct size holes.
Luckily, had  several 'spare' as JBM wasn't around making them several years ago
 You need to check at fixed throttle positions though, probably have to use 4th or 5th gear when cruising to keep out of any weirdness at specific rpm. 6th is usually OK if your staying over 65mph

I've got good news and bad news.  First the good,  I have moved to San Diego, California to start my career as an industrial designer.  The bad.  The bike wasn't able to make the journey with me.  Sadly I sold her, but she had gone to a loving home, and will live on with a new owner.
