CB100 Racer

Got the motor all back together and mounted in the frame for some mock-up:

Begining the build on the aluminum swingarm (stay tuned for more):

Very cool project. If all goes well I may have a '71 CL100 in my fleet to build a mini-racer out of myself! Being in Portland I may hit you for advice/support, and maybe one of those bad ass swing arms :)
 
I'm diggin' on this build and the direction it's headed. Those welds look great!
 
Would you sell the rough draft body work? Mainly the 1/4 fairing up front? I want something really tiny for the 175

Thanks
 
@ curbcast: I would definately sell the rough draft bodywork. hopefully I'll get the mold finished up one of these days and then I'll send you some better pics of it.

@erskine: Thanks man, yeah I'm gonna run it stock for now. I'm actually building the bike for my daughter. She's only two now but when she's old enough to ride and race it will be there. The motor can grow as her skill does. I got her a Honda CRF50 with training wheels for her 2nd birthday so she should be ready by the time she's 16.

Thanks for all the compliments guys. I've been spending a lot of time on customer bikes and havn't been able to spend too much time on this build. I'm gonna focus more time on finishing up the prototype of the AL swing arm so I can build a jig. Once that's done (along with some on the road testing) I should be ready for some production. Stay tuned.
 
Will definitely be following this one. I am working on a CL 100 right now.

Since I know very little about these bikes, I have to ask, is this the same motor as the CL?
 
Very cool. Next step for me is pulling the motor out so I can replace all the gaskets, get it cleaned up and maybe paint it.

Considering the size it's probably pretty easy to pull huh?

Yeah very easy. disconect everything, fuel pipe, wiring, throttle, clutch and tacho cables, chain etc.
either jack it to support or put loads of cushions/padding underneath, undo front engine plate from the frame rather than the front engine mounts.
lower it down. Job's a good'un.
 
Ya seams to be! Except the stupid throttle cable going through the bars. Grr. :-\

Only thing I'm a little concerned about is rewiring the whole thing.

I've stripped mine down with spanners. Deliberately, to see how far I could go. I didn't need sockets until I went beyond what would be considered User servicing.
I can really appreciate that with the millions of units made for total abuse in third wprld countries they were made bomb proof and they needed to be serviceable with a bit if string and some brown paper.

Hey two quick questions for you...

1) What did you use to get your engine so clean? Just a degreaser or did you paint it?

2) How did you strip the paint off your frame?

Thanks.
 
Wow! over a grand for a 100? You're right, that's just crazy. My local bone yard guy here has one in great condition w/ a bunch of spares for $200. I scored mine at a yard sale for $100. Keep lookin, they're around.

@treitz: I completely disassembled the engine and bead blasted all the externals in a little $100 blast cabinet that I got from Harbor Freight. After blasting, I used a good aluminum etching primer and some high heat aluminum colored paint with some high heat clear for a top coat. Paint isn't all stripped off yet but I used a wire wheel and one of those goofy abrasive "sponge" looking things that they call paint strippers w/ my drill motor. Once all my welding is done I'm going to have it blasted and powdercoated.
 
The throttle cable was a bit of a biatch. I think I just cut mine off since it was so trashed. And as far as the wiring goes, it's actually very simple. There are some wiring diagrams floating around on the internet or just get a new loom like I did for $15 out of Thailand.

Very cool. Thanks man.
 
Any update on this bike? Looks great. Im working on a CL125. I might be intrested in a swing arm and the 1/4 fairing if you make an extra.
