Title: CB750 No Plunger Hellride Freedom Machine
Post by: irk miller on Oct 09, 2017, 00:18:20
Thanks to the gracious delivery of this 70's era plunger frame from New Mexico to Alabama by Canyoncarver, I'm jumping into this chopper build with two feet. I've reached out to several forums, sorted through various catalogs and ads from the 70s, but have yet to identify the manufacturer with complete confidence.  I think it's definitely a production style frame, considering the neck.  It has two pressed in cups for a common neck tube.  The CB750 triple tree that came with the frame has a modified stem to account for the longer neck.

We're in the sketching  phase, so things can change wildly.  Ultimately, I want to avoid common cues like peanut tanks....


It took some machine work on the steering neck cups and the RM stem to make this RM front end work...

Here is sits with a 1991 RM250 front end and RM wheels front and rear.  I like the dimension of the dirt bike wheels, plus they're aluminum.   If I decide to go drum on the rear wheel, I may go 70s era XL350.

Dig the frame, I've never seen one quite like this either.. can't tell if it's a weld on rear half or whole frame.. You are probably aware that the front end may be really spongy for the weight of the bike as the build goes on.. they are designed for much more travel than a street bike front end.. I've read that the fluid movevement can be restricted with a machined piece and/or stiffer springs.. worked on a cafe Suzuki that had 250 forks, they looked cool but damn it moved around way too much.. cool project though! Will keep tabs!

That frame looks to me like a Jammer frame, canít find any reference to one with a plunger rear, but someone at some point could have grafted in a Santee rear section..

Yeah, I'm definitely considering the possibility that these forks won't work. I have tried them on a heavier dual sport contraption I built, so I think there's room to make them work here.  This is one iteration, with potentially several others. They can be valved and fluid levels adjusted to effect the dampening on these to account for weight. The rake is a big factor, as well.

I've narrowed my opinion of the frame manufacturer to either Jammer or an early Santee. Though, all the Santee plunger frames seem to have a goose neck. You may be right on about the plunger being grafted on a Jammer. The tubes which mount the springs certainly suggest that possibility...

Had a little convo with Race Tech.  I could go as high as .52kg/mm on springs in these forks.  Stock is .36kg/mm.  We'll see how it acts with weight and go from there.  Regardless, I feel pretty good that we'll find a match with rake and trail considerations.

  I imagine there will be enough travel to hit the frame to floor if I were to jump it, but running on the street will just waste most of what it has available. As long as Race Tech has the right springs, these forks should work well.  I have a VZ800 front end to swap in, if this setup doesn't work.

I didn't take any glorious actions shots, but man you should've seen me getting all the Bondo off this frame.  Fuck that 70s smoothed out look.  I learned an old body shop trick with removing paint and bondo, which is to get a fan tip for a torch and go apeshit with a scraper and stiff wire brush.  It weakens the Bondo so you can scrape it off, or brush it off.  Thick areas require a few passes.  Some of it drops in flames.  Then clean up the mess on the floor with a broom.

Thanks fellas. 

Got tires mounted.  I may go 18" or 17" on the rear instead.  This is 19" with a big ol flat track tire mounted.  21" up front.  I'll be looking at this setup for a while.

It's 1.5" taller in the rear, which is a look not uncommon for digger style choppers.

Ever since the deal with Kelly to get the frame, lots of research has happened. If it were a legit Amen or original plunger, I would've kept it a plunger no matter what. The more I dug, the more I realized someone added a plunger kit in the 70s.

As the research goes, there is only one suspension worse then a hardtail and that's a plunger. Awful ride and awful handling. Plus they destroy your drivetrain because the  suspension acts independently since there's no swing arm. Talking to some old school chopper guys, the only way to fix them is to add a torsion bar. I decided to make it a hardtail instead.

I see your point now.
I thought it would be similar to the older BMW models.  But, after looking closer, I now realize the BMWs do have a fully active swing arm.  Along w utilizing the drive shaft tube.  Just kinda hard to see exactly whats happening there as most are painted black and that suspension is hardly noticeable.

Learn something everyday...check.

If that's the case, I think I would've welded up the Plunger in a fixed position and ran that instead. That way it would ride like a hardtail, but look like a plunger.
Sadly (for me), the frame has lost it's "hook", and now looks like a cookie cutter hardtail.

Sorry to disappoint.  It was a hard decision that I went back and forth on for months.  Thanks for making it easier.  It's not a cookie cutter kit to turn it into a hard tail and it's not cookie cutter axle plates.  That's all done by me in my own design.  I figured I'd lose some fans of this build with the decision, but I gained a few inches in length to sit (which it needed) and I won't wobble and die at high speeds (which is common with plungers).  Not sure how welding up the plunger to make it into a fake plunger is better than turning it into a hardtail.  I'm not into faking things.  I might not always do it right, but I do it honestly.  Considering I've just been told that it's a waste of these USD forks on a hardtail, I'm definitely building a roster of vocal critics.  I'm sure this build will attract way more vocal critics than I have now.

I wasn't trying to bash or suggest you should do anything differently. Nor am I disappointed. I'm of the opinion that "it's your bike, do whatever makes you happy".
I'm no Bob/Chop suspension (or anything else) expert, but it seemed to me the "unusualness" of the plunger rear was the draw. Now it no longer has that.
And all I was "pondering" with making a fake plunger was to keep the unusualness of it while improving the function. Fundamentally the same premise as using a vintage headlight and/or taillight shell, but installing LED fixtures/bulbs to improve visibility/safety.

But you do you dude. Don't let me interrupt. I'll keep my uneducated musings to myself, as not to be lumped in with the rabble rousers ;) :P

"The Hellride Formerly Known as Plunger"?

Lol

True it loses some uniqueness without the plunger  rear end, but as you said Irk, it wasn't born that way, and the plunger that were cobbled from hardtails were even more unsafe than the handrails they started out as. Kind of like those guys who make a "hardtail" by bolting some steel rod in where the rear shocks used to be.

It may not have the same character, but it's still pretty sexy looking! My only gripe is that you seem to be able to turn out projects faster than I can read your posts about them!

And I for one like the forks. Wasteful or not, they give it character that a cookie cutter hardtail will otherwise lack.

Not sure.  The length really doesn't seem bad.  I'm waiting on the screws to mount the rear sprocket then I'll measure it up.  The local dealer didn't have a long 520 chain in stock, so I have to order.  I have a tensioner here just in case.

Thanks, Mike.

A couple quick little updates...

Brakes: I have to figure out a tab for the rear stay. Something I can try to machine tomorrow.

Sprockets: I'm running a 38 tooth rear and a 14 tooth counter. The counter sprocket is an XL250 sprocket, with a machined spacer.  Honda ran a common counter shaft tooth for several bikes, which is really convenient when you want to convert a CB750 to 520 chain.

I promise, I'm still a hack.

I've decided to go with a first gen XL350 tank, because I like the shape and I have an idea for placement of my ignition switch. I saw opportunity in the cutout for the carb.  This tank is just for mocking. A good tank is en route...

Seat pan is basically done. Waiting on the springs, then mount. Covering may be the last thing I do.

Made a remote m/c and reservoir so I can run a simple cable control on the bars.  The unit will get welded underneath the tank and  a short Z50r cable will actuate the lever.

Thanks, Cookie. I got the priority fender, so weíll see how this goes.

I took a chance on a homemade $10 oil tank on Ebay. I was pretty sure it had 750 size connections and it in fact did. The question is if 1.25 quarts is enough.

The new XL350 tank got delivered today. Itís got a few dings, but man the patina is glorious. Iíll have to think really hard about painting this tank. 

(https://uploads.tapatalk-cdn.com/20171025/de03c71827d464c86f9dc0c881635688.jpg)

I also began work on a Cush drive conversion experiment. Itís an RM250 wheel, so no Cush. I could swap for DR350s, but people want silly money for them.  I still have a few details to work out, including casting the urethane innards...

I decided to mount the oil tank tight to the engine. Except now my stock feed line just slightly wont fit. It may not be an issue anyway if I run an oil cooler.  I may run a cooler in the bottom of the frame behind the motor.

I'd vote yes to the oil cooler, you live in the south and it'll add room for a bit more oil than that little tank can hold.  The oil cooler I added to my chop sure helps with summer oil temps.

I ordered a cooler from a 2003 Eiger 400.  A shot in the wind on size, so we'll have to see when it arrives.  If it doesn't work for the chop, then it can go on my DR350 since they are fundamentally the same engine.

Thanks, Doc.  It's a different look for a chop, but I like it.  One caveat, obviously, is the lack of tire options which is why I went medium compound flat track for a fatter tire.  Avon makes an rear tire (AM7 4.00-19) that I may try next.  It's a cool looking vintage tire with more of a square patch.  The only other options I've found are a Metzler Block-C (3.5-19) , Avon MKII (3.50-19) and the Avon Roadriders (3.25-19), which are front/back tires.

I was able to get a DR350 hub from a member at ADVrider. I reached out to Buchanan to see if we can match some spokes.

A little update:

Front brake is done.

Iím running a Z50 cable from the lever to the m/c. Then a 3an straight fitting instead of a banjo...

(https://uploads.tapatalk-cdn.com/20171121/c430c4c91040eead71177c37de317b1e.jpg)

The caliper has a banjo to 3an fitting.

(https://uploads.tapatalk-cdn.com/20171121/a8945976ec751fd1a6c661d12f8db82c.jpg)

Then the top fork guard mount is altered (tabs removed) to accommodate a brake line guide. The line runs through a machined sleeve of black acetal.

Just to keep this thread a-moviní along...

Iím kind of stuck trying to get the oil cooler/tank situation sorted. First, I ordered an Eiger oil cooler, which was too long. So, I swung again and tried a Suzuki Intruder oil cooler...

(https://uploads.tapatalk-cdn.com/20171201/dd9e8327e2fab5e480aaa6e7c7059cf4.jpg)

Muuuuch better.

I also ordered some extra length of SS line to give me some extra volume...

(https://uploads.tapatalk-cdn.com/20171201/913ced80c78279ebbc199b6354227e66.jpg)

Then I separated the case fittings from the stock lines, which basically match to 10an hose...

(https://uploads.tapatalk-cdn.com/20171201/a5e1024c7fcaa8e9fcec40a6da6fe470.jpg)

Now, itís just a waiting game on some hose finishers and the fittings for the cooler. Iíll convert the banjo fittings to a setup with M12x1.0 to -10an fittings.

Note to self: donít order from China unless itís a last resort. You prefer days over weeks for delivery. Nothing stalls a build like this.

Made a few moves on the chopper and maybe hit a snag too:

 I pulled the cover, checked compression, and a few other bits to get an idea of the life of this motor. Itís showing 160 compression across all 4 cylinders.but the motor lost power above 60mph and fouled the #4 plug. I always thought electrical, and Iím back to thinking that again.  For now, I buttoned it back up in anticipation of wiring. 

Next, I installed the F2 exhaust and found that it doesnít quite clear the frame at the collector and hangs low enough to give me shit for lean clearance.  Fuck.

(https://uploads.tapatalk-cdn.com/20180121/5f85e0676a651f865f73adbfc4c77874.jpg)

I have to decide if I want to alter this exhaust with some heat to get the clearance and pull it tight to frame, or fork out the dough for another exhaust. I could probably afford another exhaust for what these can sell for.

(https://uploads.tapatalk-cdn.com/20180121/2340e1716dc33a2d2b43c499e63b2609.jpg)

Otherwise, Iím very close to wiring it up and at least hearing it run.

(https://uploads.tapatalk-cdn.com/20180121/0dcf7c634ad6a4ece11b387abeb9463b.jpg)

Also: seconds thoughts on the style of seat, so weíll hold off on covering until there are no doubts.

Trying to decide if I want a seat that is more boxed out underneath to hide electronics.  I have that box you sent me with the frame, but I may try to go a little more hidden.  I do like this seat, and with the Italian leather, it could be sexy. Just thinking through electric ideas and ways to hide it.

I like that tank on your bike alot.  Fits the lines well.  I had another thought.  I would go with a longer front end.  Crazy maybe but , another few inches, it would sit the engine slightly more vertical and help with the ground clearance with the pipes.  I like those with the leading axles you have, maybe drop triples for a different offset ? 
It would also be rad.

Either way, I wanna see this one through.  I dig your chop.

It's possible that the forks are dropped an inch or two from the weight of the bike.  I haven't gotten Doug to set these forks up for this bike yet, since I need to have it more compete to give him the weight.  I've definitely noticed it drops under weight.

Then I tried out the RM front and thought is was neat and different.   Well, with a low clearance issue I decided to revisit the CR front end. Much better ride height and I think a better look...

Spending a little time catching back up from the ground I lost changing the hub and oil tank.  I machined the spacers to get the rear wheels sorted.  The sprocket and rotor are en route, so there may be adjustments still to come.  One thing I'm figuring out, the DR350 and the RM shared a lot of parts.  The DR350SE and the RM do not.

I also plumbed the oil tank.  It took going from 1/4" npt at the tank to 10AN in the lines and the motor.  I drilled out the adapter fitting coming from the 1/4" npt elbow at the tank to keep the flow from the motor consistent.  There is very little options out there for a 1/4" npt to 10AN adapters.  These ones came straight from China (the fitting coming from the stainless steel elbows at the tank and connecting to the 10AN elbows for the ss lines)

Got the seat back to mounted, as well.  I tried to neaten up the spring mounts by machining and threading some delrin bushings.

The bushing in the first pic slides into the spring and mounts the spring to the seat.  Then, the bottom of the spring slides onto the bushings threaded onto the frame.  This allows the seat to hinge up.

I decided to get a better seat hinge.  It's still not the top dollar hinge, but it should suit my needs.  One thing, though, I didn't like about it is the hinge pin was a basic nut and bolt.  Nothing fancy, and certainly nothing nice looking.  So instead, I upgraded it a bit by machining a delrin hinge pin.

The pin stays stationary, while the hinge rotates around it and it will hold in an upright position, which will make working under the seat easy.

Yes and no.  The one bolt to the exhaust bracket could be removed and the pipe pushed up slightly for better access.  The axle, when pushed furthest back, should clear the pipe with the bracket bolt still mounted.

Ha!  When we were designing the art school for Temple, we're in a meeting choosing equipment.  The fork lift would be shared, so I needed approvals from all departments.  The Sculpture professor argued with me about the unit I recommended because there was only 1" of clearance from the highest point of the fork lift to the smallest door it would need to go through.  I had a hell of a time convincing her that even 1/4" clearance works because fork lifts don't grow.  And when their tires wear, they actually get shorter.  Blew their minds.

Sounds like educational bureaucracy at its finest. I can't count the times in our trade school that a decision was made for a purchase by the least qualified individual to make said decision, due only to their position in management. Then later on, we are asked why "we never use xxxx piece of equipment?"

On the forklift thing, the last place I worked, we had a lift that the mast wouldn't fit though one doorway by about 1.5"... until the new guy straight up Larry enticer sent it full speed while not paying attention. It now fits, if only in the same spot, just to the left of center iirc lol

Might not seem like much, but I added an inch to the fender struts and moved their angle to match the down tube in front of the seat. This changes the fenderís orientation so that it matches the wheel shape much more neatly. It makes for some nice  filigree.

I took some time off from working on the Mid-Ohio haul to make the chain tensioner.  I machined the drum and welded an old gear shift lever to it and a cap screw to the shift lever.  I machined a bronze bushing to insert into the drum, then on the backside I machined a delrin bushing to fill around the bronze. 

In all but the last pic, the arm is basically straight.  In the completed unit, I bent an "S" into the lever which centers the skateboard wheel over the pivot and moves it clear of the frame.

In this pic are all the components minus the spacer to go behind the skateboard wheel that centers it to the chain.
(http://www.dotheton.com/gallery/77150-120718152111-40371124.jpeg)

This is the backside of the tensioner, where the delrin surrounds the bronze.

(http://www.dotheton.com/gallery/77150-120718151555-40352167.jpeg)

Here's the unit put together with the spring from a kickstart mechanism.  One thing that changes on the spring from what you see in the pic, I spread the first coil out to help put more tension on the spring and to help it spring back a little better.  That may not have been necessary, but it doesn't hurt either.

(http://www.dotheton.com/gallery/77150-120718153940-404077.jpeg)

Another view of the arm and pivot.  Notice the drum isn't machined square, but instead has a curve to it.  This helps the spring move toward the arm and keeps it from binding in front of the mechanism.  It also gives it more throw, as the way the spring works the ID shrinks when the tensioner actuates.  I didn't want the spring too loose, but too tight kept it from swinging very far and it would bind.

(http://www.dotheton.com/gallery/77150-120718153941-4041849.jpeg)

This is the pic of the completed tensioner.  The arm is bent, which moves the wheel back toward the center of the bike.  The arm is also shorter than in the previous pics.

It needs to be wide enough to keep it on the wheel, and the wheel will develop a groove that keeps the chain inline.  Some guys on the Hondachopper forum say a tensioner is noisy or no good.  We'll see.  One guy used a sprocket tensioner and claims it makes the chain wear faster. He went to a static tensioner with an adjustment. The other guy decided to go without a tensioner at all.  So, neither was like mine.  The spring doesn't have a crazy rate.  In fact it's not much at all.  The wheel is really to keep the chain from slapping around, much like an idler pulley on a car.  They don't exert a whole lot of force on the belt, and neither will this tensioner.

Been telling myself all summer that I want to try to learn to hand stitch leather. I'm not one to practice on scraps or random shit.  I just jump in with two feet.  I figure, If i fuck it up, I'll just do it again.  So, my first attempt at a hand stitched leather seat...

It's an Italian leather my mentor, friend, former boss, and graduate advisor, Nick Kripal, gave me 7 years ago.  He passed away last year from pancreatic cancer, so I knew it was time to do something proper with this skin.

Awesome homage to your mentor. You could buy any seat out there and still not have one with that much value.

Thanks, yíall. I sanded and burnished the edges, which I shouldía done before the previous pics. It cleans it up a lot. Also, rubbed it in mink oil to help make it waterproof.

Next item I lucked out with is a Henry Abe breadbox air filter. It had rust on the face which polished out decently enough. Cost me $45 shipped from a dude on Hondachopper.com.

This is why I like to post progress shots, to see how everything looks as a composition.  I hadn't thought of leveling the seat.  It's worth a gander.  Placement front to back is relative to ride position.  I have 1.25" to the fender and about an inch to move forward towards the tank.  I'm a shorty at 5'6", so the seat's current spot puts me at a good relaxed posture.

Since this is going to be kick only, I'm deleting the starter and using the starter tray for an electronics tray.  What isn't under the tank, or in the headlight bucket, will be here. 

Since the starter tray lid mounted to the actual starter, I need another way to attach it, so one screw will thread into the starter delete plug.

I watched my boss lock up his rear wheel because of a tube setup like that. If the brake fluid gets hot and expands, there is no where for it to go other than to pressurize the system and push the caliper piston out which makes it drag which makes it hotter so you get a positive feedback loop, until lock. Or as the pad wears the pistons retract too far because more fluid cant be pulled into the system because of the vacuum.  Thats why the caps of reservoirs have those funky rubber inserts to expand and contract with the system.

Hmm.  I wonder if I can come up with enough of a loop or extra space or something else.  I could go 3X, 5x or 10x on length maybe.  I'm mainly trying to avoid hanging a huge reservoir somewhere on the frame.   One option I considered is hanging the reservoir somewhere under the seat where it's visible, but not in such a profound space.  Having the M/C is a lot of visual clutter, since it seems like most vintage choppers run a drum.

Well, there are some necessary tweaks, but I can officially call it a runner...

https://youtu.be/8A9EI-tdhX8

I have a couple glitches in the wiring, namely the running light isn't coming on until you tap the rear brake.  I made a circuit that runs the running light through a resistor and the brake light through a wye that bypasses the resistor.  I also figured out why this motor has had electrical issues for the last three years.  That issue is me.  After frying my brand new Shorai lithium battery (ouch!), I figured out that I didn't understand the inner workings of the alternator and field coil.  I had been wiring the exciter as a power source, thereby grounding out my system.  Eddie hooked me up with a Rick's 8 wire reg/rec a few Barbers ago.  I was trying to run 5 wire reg/recs and wiring them wrong.  Now that I figured out the Rick's, it's all good.  Just waiting on the replacement Shorai to take it on a ride.  This run was on the bottle and with a spare battery on the ground. Oh, and the carbs were pissing fuel.  But, it runs.  It runs.

First two suggestion still include painting it. ;) LOL.  It's actually patina'd pretty nicely from the New Mexico desert air where Kelly got it from.  I just need to get the hardtail to match.  I have some tricks to do it.  But, why I'm considering not painting it is because the patina is really good.  Plus, the wear marks on the tank set up nicely for the frame as it is.  The rear of the tank where the original seat was has no paint.  The paint has completely worn through.

I just rebuilt these forks.  I didn't take any pics, since it's so hard to visualize all the cussing and slinging of fork oil all over the shop.  Funny thing, no internet searches reveal any information on rebuilding the forks for a 1985 CR500.  I had to figure it out myself.  They have some bushings which will throw you for a loop and the typical age stuff.  All in all, it was a blast.  A real blast.

About 80% of the rat rods (and there are hundreds around here) in this area are done that way. Just says to me that they care more about performance than appearance, and that's cool with me as long as the power train is not stock. We will see in a few years how they age.

I've done two tanks now like this (minus the adhesion promoter) with different results.  Seems like moisture is retained in the steel - the more you can drive that moisture out by heating the tank before the 2K, the less rust will appear under the clear.  At least that's what I've found.  Fair bit of rust now on the one tank I cleared in humid conditions, none on the tank I cleared after heating it.

Mind you, the rust that does appear is weird.  Never seen rust like it - it looks like hairs.  Peculiar.

Mind you, the rust that does appear is weird.  Never seen rust like it - it looks like hairs.  Peculiar.

Chopper's looking killer man.   
Thanks, Jim.  The structure of the rusting probably has mostly to do with the surface of the steel- sanding marks, etc.  The water fits into those marks and becomes rust later.  If you treat the metal with a solution of phosphoric acid such as OSPHO before your clear coat, I bet that doesn't happen.

The low bars do look better.  Just sayin, I started with drag bars and forward controls on my chop.  I'm doing 12" apes now because they are way more comfortable for my chassis.

The low bars are really comfortable for me and this bike.  If 12" apes were more comfortable, I would most certainly run them. That said, I think the look of these low bars makes sense with this bike too.  I was hoping to keep it somewhat out of the box, hence the dirt bike wheels and forks.

Your bars fit the bike really well plus yours has mid-controls for your feet which is nice.  Mids really change the riding position, it's why I'm doing mids on the FXR.   More aggressive, less laid-back.

It would be really dumb of me to say itís comfortable without sitting on it, or to get this far into a build without knowing it fits. I usually try on my shoes at the store, not when I get home.

Cool.....the reason I asked is it looked very short between seat n pegs, being as they're not forward pegs. I'm noticing on my build as I've reduced the seat foam thickness a slight over bend in my knees that cause pin n needles at more than 30 mins in the saddle. Carry on....:)

Yeah, my pin and needles issue is in my arms.  I have a crooked back from years of abuse, which creates amplified issues in the hands and joints.  So the location of my hands is of a particular importance for me.  I considered the forward controls for my feet, but for whatever reason, I'm not comfortable in that position.

The video named "No Plunger"...

I can see it now, a dad, taking care of his 9 children while the mother is away.

Little Billy had a chipotle burrito earlier that day, which inevitably over worked the abilities of the commode.

There's "water" everywhere.

The father, much to his dismay, realizes that there is not a plunger anywhere to be found...

In a panic, he goes to the trusty internet and franticly types in "NO PLUNGER" to find out what to do in this sticky situation.

What he finds is your video of this freedom machine, and for a moment is taken-a-back from this 9 to 5 job and doo-doo flooded house.

He sees himself, in the wind, leaving it all behind...


Snap, back to reality...

"water" everywhere

Little Billy and his siblings are playing a dangerous game of "gravy train" slip and slide down the stairs

The air is getting thick in the house, and the day has taken a real turn for the worse.

But in the midst of all of that, dad got 30 seconds of his life back, at 21, free and alive.

YOU DID THAT ERIC!

that alone makes this build worth it.

Another update.  I've been putting some miles on it to sort out the kinks.  Right not, it's acting lean, so this bread box may be the culprit and a re-jet may be in order.  I still have a few turns on the mix, though.    For the first time, I have this thing properly charging.  Yay.  The chain is hitting the rear fender just a bit and every now and then.  This is why I haven't painted it.  So, I'll cut it out just a little bit more.

If you look closely to the right side of the image, you can see the groove forming from the chain wear...

Fuse box and power buss are located under the starter cover here, and the reg/rec mount.  The reg/rec sort of floats off the tranny, so hopefully it stays cool enough.

I also took a sort of bulky and cheesy license plate dealio, took the light/frame/plate mount off of it and stole the bracket.  Machined a cup/bushing so I can mount it above the axle instead of through the axle as it was intended...

Question for you.  This LiFePO4 read 14.6v or 14.8v after a long ride this weekend.  Should I be concerned?  I haven't retested to see if the voltage dropped after sitting awhile.
Title: Re: CB750 No Plunger Hellride Freedom Machine
Post by: Sonreir on Sep 04, 2018, 10:49:46
14.6V is fine, but I would start being a little concerned if it goes past that (even by a tenth). 14.8V is the absolute safe maximum. I usually advise the 14.6V number because the 14.8V means every cell in the battery is at the full max value.

You might be able to bring the charging voltage down a little by routing the black wire from the R/R to be as close to the ignition switch as possible, with as few connections as possible.

I finally got some paint on the rear fender, and wrestling with the idea of clear coating the tank.  I'm not against, though I don't think it's all that necessary either.  At least with the fresh paint and deep clear on the fender, there is an obvious difference.

FSM for the GL says 14 - 21psi.  25 psi is not a crazy amount.  Pressure for most of the dirt bikes, like the 200r is 12 - 14 psi max.  I'm not jumping huge berms or launching off of cliffs, so I'm pretty confident they can handle more pressure.  Plus, the rake softens the ride considerably too.  This isn't exactly a factory application of these forks. ;)

that makes sense. I know under compression the psi raises a good bit, and also a good point on jumping curbs. (though a video of you jumping curbs on a hard tail chop in shorts and a tee shirt would make you way more cooler...) lol

I am half tempted to see if it will jump, but then I remember who welded the hardtail on.  LOL.  In the end, I may get Dave Doug to work this front end with springs and shims.  Funny thing, when looking up the numbers for these forks, there are guys that say the valves are just to remove air, and there are guys that say they wouldn't have the valves if they aren't supposed to have air.  Some say 0psi and some say 7 - 8psi and some say as much as 12psi.  I defaulted to GL1100 numbers, since it's a pig heavy chopper.

haha, I mean it is like "half dirtbike".. Ive seen roland sands jump Harleys with way less dirbike pedigree. The only thing I worry about with to high of psi is blowing out fork seals, which as you've shared isn't a fun job to replace on these forks. They may well be fine, not saying im right lol I was just more curious.

I'm not sure on the possibility of blowing out fork seals in the sense of having to replace them.  I can see it being possible that they blow out of their seat, but since they are basically wipers, dirt/grit is the bigger enemy for causing leaks.  That's why those Seal Mates work, because they clean out the dirt and grit from between the seal and the tube.  As long as the rubber is good, I've been able to stop leakage on several forks.

Because of different seal and plunger areas, different forks have different maximums. My KZ750H forks max at 36 psi (250 kPa). I've seen others list 15 psi as max. Even with 36 as max, 15 is very reasonable considering the angle that these forks are at. I'd think softer would be easier on the tubes, allowing the forks to compress more instead of bending. You've put so much effort into this ride, it only makes sense for it to be safe and comfortable for you to ride the fool out of it!

What the hell is that?  Is it rust?  Im sure you've already done all your homework on this "browning" process.  FWIW...

If it is REAL rust.  It will be very fragile at first. If it turns a copper color you will need to add more humidity. 

The "copper" colored coating will prevent the acid from doing its "rusting" job.  And will have to be sanded back to bright and re-done.

You can buff the new rust using soft old denim.  BTW - buffing rust is called "carding". Or even steel wool.

Carding, between acid coats, will give the rust a mice smooth, darker, semi-gloss type finish.  (probably what you want)  If you dont buff it will get rougher as you build it up.

Carding all that by hand will be a big job.  Maybe wrap a drill buffing wheel w denim.  working at a slower speed.

But you will need to remove a lot of stuff from the frame to get it all nice and even.

You can stop the browning process w water and baking soda mix once you reach your desired goal.

Which you're probably there now.

It's pretty clearly a rant.  It's always a rant.  I'll be happy to mail you a copy of my resume, if it helps.  My portfolio is available online.  There are many ways to do this this and several processes.  The front half of the frame is already rusted naturally, so (as I stated before) I'm just making the back section match.  I don't want it "even".

Its pretty cool your going for the match.  It will be a neat finish.

Im betting fine steel wool will better achieve the uneven "worn" appearance, letting some bright shine through.

Really dude its super cool.

I prefer the browning of rifle barrels as opposed to more modern blueing.  An art thats fading fast.

I totally agree.  Same as I much prefer wood stocks ( I assume you do, too) to the plastics they're using nowadays. 

On similar note, I'm also trying to patina the seat.  Partly because I dripped brake fluid on it (yes, I'm an idiot), and partly because the color tone was too consistent and light and didn't seem to match the ride.

I donít care for the color of the oiled hide I bought.  Used it on the stool I made.  Let me do some experiments on it.  I got stripper and also gonna try some alcohol.
To strip current tan finish off and re-dye dark brown.   Iíll send pics tonight.

Bleach or acetone will remove the dye in leather.  You then can add color back in with wood stains, or shoe polish.  I cut the shoe polish/stains with saddle soap or leather conditioner and rub it in.  Coffee grounds make a great dye for leather and if you want more of an oxblood tone then boil red onions or beets.  If you can soak the leather, then rusting some steel wool in a solution of vinegar (search: vinegaroon dye) to make a great black dye.  By trying, it's not a question of knowing.  It's a process of effort.

I finally got the front forks sorted by taking all the air out (yes, 0 psi) and swapping the 2.25" shim that came in these forks for a 5" shim I made from PVC pipe.  Yes, these now have a 5" long shim.  LOL.  I was getting way to much sag in the front end before the swap, but now I get zero.  The ride is a little on the stiff side, so maybe I cut it down a bit, but I thought it rode pretty well.  It also got me much better clearance for my pipes, which help my right turn lean.

The other bit of work this weekend involved converting the seat more to black and more patina on the frame.  This black in the seat is achieved by mixing a 3:1 solution of vinegar and hydrogen peroxide and dropping a wad of steel wool in the solution.  Then, with sandpaper and steel wool, I buff the leather and follow up by soaking a rag in the solution and wiping down the seat.  A rub down of leather conditioner follows that and I'll finish with some mink oil.  I don't want it solid black, but just darkened up and the look of some wear.

Not sure it was advertised, per se.  I usually do the Greenville ride, since it's down the road from my mom.  But when I looked up the rides, I saw there was an Augusta ride.  A few guys there said the coordinator was finding people downtown when their bikes were parked and passing out info.  It will happen again next year, so I'll message you.

My first bike was a 650 Triumph Trophy (TR6C) with bolt-on Corbin Gentry hardtail, K&Q seat, 12" over springer, peanut tank, pull-back butterfly handlebars, etc. I loved it and rode it quite a bit (but, I was at sea 50% of the time). Even with Lucas electrics, it never completely let me down (although I spent several hours next to the road with the gas-powered soldering iron I carried on a couple occasions). Its downfall was handling in traffic. It just responded too slow to feel safe around Charleston, SC drivers that seemed to have all sailers on motorcycles targeted. You have done yours tastfully without going too far on any of it, and it looks like the frame geometry is fairly conservative. It should grow to be a  solid part of you.

I do like it a lot.  Certainly something to get used to.  Since I shimmed the forks, it is significantly improved.  They were way too soft and had almost 2 inches of sag, which is ridiculous. 

So, when were you in Charleston?  I was there 89 - 94.  I was on the USS Semmes, DDG18, a Machinist Mate, MM3.

Well, I finally sorted my issues with the PD carbs. I threw them aside and ordered a kit from Murray. Holy shit does this thing run beautifully now. I had to flip the intakes to fit this chopper frame, and I made my own filters from two layers of aluminum screen with Uni filter media sandwiched in-between.

Making some tweaks to the carb kit to get fitment with this frame. I couldnít get enough clearance either inbound or outbound to get an air cleaner on the carbs, so I put the flange side down on the intakes to a belt sander and ground an angle to each side, then followed up with oil and sandpaper on a surface plate. The K&N style filters still donít fit, so weíll make our own. The plan is to add a Uni element under the screen, but I have to secure it to keep it from getting sucked into the carb.

No, but I did use Sharpie. I'll never use Sharpie again.  It etches better when you lightly brush off the surface, which also cleans off the Sharpie.  So, I had to chase back in the angled edge on the lathe to clean it up.  I may actually start over again to get it better.

Alright folks, so here's the bizness.  As you know, right before Barber, I installed this Murray's Carbs kit.  I was over the PD carbs, and Murray has always promised me I will love this kit.  He was kind enough to quick ship them so I could have them for the weekend.  At that very moment, I started going through insulator hell, and insulator hell continued until this week.  There are some crappy aftermarket insulator kits on the market and the 77/78 stock insulators are not the easiest to come by.  So, when I was at Barber, I bought the K0-K6 insulators to see if I could make them work.  I then bought some 77/78 insulators from a guy on Hondachopper.com and another set from Ebay.  Neither were leak free.  I kept thinking the carbs were lean at the top end and not quite right in-between.  Lots of conversations with Murray, and lots of going through my motor for me.  Went through cam timing, valves, ignition timing, sprayed boots, etc. Nothing revealed itself until a few days ago when the #1 carb started going significantly lean.  As the same intake feeds #1 and #2, but #2 wasn't lean, I knew there was something going on with the insulator.  So, on a whim, I pulled the k7/k8 insulators and installed the K0 - K6 insulators.  This is my review:

Holy Shit!  This, my friends, is a drag bike with no engine modifications whatsoever.  It pulls like a freight train.  I have no times yet, but I can tell you it tops 80mph between the light at Furys Ferry Rd and Warren Rd on Washington Rd in Augusta.  Google Maps says that's between .1 and .2 miles. It's right at 1/8 mile.  There's was more left in the throttle, I just didn't want to die.

Regardless of scientific data, this is an oh shit, white knuckle carb kit.  One which requires good grips and a sticky seat.  I'm running a 16T front sprocket, so I expected more bottom end, but I didn't have high hopes for the top end.  To give it a go, I got onto I-20 and sifted into traffic.  I picked my moment then, from a 75mph cruising speed, I hit WOT and again about lost my shit.  It pulled as hard at the top end as it did at the bottom.  If there's any skepticism whether or not running two carbs works, I promise you they work amazingly well.  I'll be reaching out for Dyno time to get really concrete numbers.  I know for one, it's made me hungry to go 836cc.

To recap, this is a Murray's Carbs kit running on a 77 motor with pre-77 insulators.  As posted before, I installed the intakes backwards and plained the face of the intakes at an angle to give the carbs a little more outbound placement for this frame.  If the frame was stock, they would fit with no modification.  Then, I rotated the insulators to level the Mikunis at 15į.

Plus, it gives a place to mount a temporary fender should you need go ride in (or after) the rain. It may have been early 70's, but I still vividly remember the front tire on my Triumph chopper pumping water from the road UP my nose!

I redid the seat in oiled leather. Much better grip and feel than the slick Italian leather...

Really really nice work.  I definitely dig the new cover.  Texture is important too.   

Is it beard "oiled leather"?

Many thanks to you and everyone else.  I'm definitely much better with my hands than a machine when it comes to stitching. 

I put the panty dropper back in line while I re-image my R100/7.  When I'm ready to paint the BMW, I plan to paint the panty dropper, too.  The plan is to paint my DR370 at the same time.  Hoping it will be easier and more efficient for the way I'm set up to do a few at the same time.  My other CB750 chopper may fit into this group as well.  Regardless, I have a Mid-Ohio deadline in July to bring a few of these for sale.

Yep.  Seems like we had to work our asses off to sell parts, but the bikes practically sell themselves.
