Topic: Dry clutch on CB750

[voxonda]

Good weekend, had a lot of work done to the bike with the clutch, just waiting on a cooler and Goodridge stuff and than it should be ready to fire up. Have made some adaptors to fit the oillines to the oem oiltank. Fitted a 2" Monza cap on the tank. Need some calipers, but decided to fit the front of my Japauto replica to speed things up.

can't wait!!!  any idea of when things will be "done"?

[voxonda]

Hey G,

Need some family time this coming weekend. Bike is getting there, see if I can make a pic. Am using the -10 size oillines but need to make some minor changes to the adaptor on the oiltank, couplings are touching the engine.

Since I have not that much time on hand, things are not progressing the way I wanted. But I'll get there eventually...........
My Japauto replica gets his well deserved wintersleep and a little overhaul these coming winter, and decided to speed things up another notch with the dry clutch bike, to dismantle the Japauto and use its parts. Oiltank, front assembly and exhaust.
In a later stage will decide to build the new parts for whatever bike. Will shoot some pictures this weekend for you G.

Rob.

 I envy your ability to work on your own stuff. I may have to shut down operations to get my CBX, 1986 GXSR750 projects off the ground.

[Bill/BentON Racing]

+1.I've got 5 customer projects,Stage III head in the mail.......and rumor mill says CB750A also to wrap up!
Mike,my heads not going to go on as quick as I thought....but won't sit on the mantle too long! Bill
Voxonda looking good..you still want a set of Yosh alum rods?

[voxonda]

Hey Mike, it is not always easy to find time to work on my own projects, keep my customers sort of happy and working the day job. But hey.......we've chosen this 'hobby' didn't we?
Must say it is still a very nice way of spending hours. And once that magical moment arrives that it is started up for the first time, feels almost like when your first born.
@Bill, yes still looking for a good set of the Yoshi's. Had some very good experience with them in a 750 racer.

Cheers, Rob

Mike
Sometimes you've just gotta do what you have to do or it won't happen.
I can empathise.
Next year is going to be a big life change for me for similar reasonings.
Continually I ask "Who is the boss?"
Everything will always work out.
They pulled all of those guys up from underground in Chili and that's good enough for me.
Sorry for the hijack Rob.

No worries, Mick. You're more than welcome.

so Rob...  ANY clue on a price point for this awesome piece of engineering??  i have a student loan set to be dispersed soon and i'd like to know what i should put aside to at least cover the costs!    pm me if necessary please!

also, any chance for the points covers to be made with maybe a mesh screen to keep debris out but let air pass over??  it's either that or one of frankenbikes clear covers...

[voxonda]

Hey G,

Just PM-ed you.

Cheers mate, Rob

[wannabridin]

rob,

any updates?  i noticed the site was still down last i checked, so just seeing how things were going over in your neck of the woods!

[voxonda]

Hey G,

At this moment living in a troubled world, but hey that's all part of life . Site is coming along just fine now, think my son needs another day to finish the site so it can be launched again. Testbike with clutch has run, but had a lubrication issue with the cam . Had to rebuild the head, new cam and towers. Did OK but after a while something must have blocked the oiljet. Will make pic, weather permitted, 'cause the weather is dreadful overhere now. And as soon as possible will make a vid and put it on the site. But I can tell you that when it ran, it gave me goosebumps, really.......

Cheers, Rob

[wannabridin]

Well that's probably because you're a god for these bikes!!  Now were these goosebumps from clutch noise or exhaust?

Had the same problem with an engine here a little while ago Rob. There where 2 problems . One was a partially blocked jet (a sliver of steel from something in the engine) and distorted threads/nut on the oil feed cylinder stud. Oil was going past the threads and bleeding oil pressure. It was the main problem. You could see it when pressurized air was put into the oil pressure switch hole. I now use a copper washer and a acorn nut on the 2 oil feed studs. The parts are the ones used on the "dead" oil return studs of the F2 head.

[voxonda]

Thanks Mike, have looked at the oil feed studs and they are as new. Have used new high nuts. Think the problem was that there was some residu left in the oiltank caused by drainage thru the pump, which left the tank dry. Looks like I missed something when cleaning.
Thanks for the advice on the compressed air test. Will, for sure, use that in my next build.

So Rob, how are things progressing?? :-) :-)  hopefully everything at work went smoothly with minimal hiccups??  Hope all is well brother!!

Hey G, thanks for your concern. Every hiccup is one to many but things are smoothing out now, you cannot change history and should concentrate on things to come.
The clutch is slowly progressing, had a runner but then one of the oilnozzles in the head became blocked! Had to rebuild the head and put in a new 41a cam. Engine is running again, have to mount the small battery in the seat and take her out on the street. Winter is coming, but will take every opportunity to take her for a spin.

Cheers mate.

Rob

[wannabridin]

hey, as long as the roads are try and the tires aren't hard, i'll take a bike out!! 

Had to rebuild the head and put in a new 41a cam.

so did you already have a 41a in there, or did you "have" to upgrade??      have you checked out kayaker's batteries he has on clearance??  i ordered one and it got to me 2 days later.  super small and lightweight!!  http://www.build-stuff.com/x-cell.htm  might as well try to spring for one for $70?? 

[voxonda]

"Had" to upgrade. The oem F2 cam went into the trashbin. Got the 41a and a 63b, but the 63 is for another upgrade. But that F2 engine is really so much stronger (faster) than the K-series. Have shorten my end gearing, it is hard to keep the front wheel down. Of course it is a K-series frame and swing, and will definitely put a longer swingarm in. These short runs makes me wonder what will happen with a set of CR's or Mikuni's. But let's concentrate on the clutch for now.
These batteries looking good and much cheaper than the ones I (can) supply. I now use a 5 Amp battery, just kickstart and no light.

Rob

[wannabridin]

any chance you have a kickstart plug you make or can make?  i want to go kick only so that little battery should suit me just fine with a headlight and brake light.  i don't want to get this off topic, so could you PM me and let me know if you can make a plug and also, what all you removed to make it kick only?  (i'm in search of less weight and less crank rotational mass!)

A kickstart plug or an electric start plug?

[voxonda]

+1 Ron,

I will PM you G.
