Topic: 1980 750c Cafe Chop, feed my dream!!

[80cafechop750]

Well whats new guys, gals I am a new member with dreams....
My first bike a beautiful '80 750c, yeah i gotta be twistwed from all u f and k peeps but I quickly rode it in to the ground...
Got a rebuilt motor for about $200 and decided to start my project, a nice cafe chop.  I being 230 and 6'4" loved my small sporty cafe but wanted stretch and comfort.  Any and all tips and feedback on direction of my idea and rake angles and swing arm stats are welcomed!!! I am young with a dream i like rat style stuff i have seen but basically need a few things and worried about a few issues..

1. fat rear, the stock 180 is a baby and i want 240-300 for my back end
2. Next issue swing arm got cut and stretch it...best places to cut weld? type of weld?
3. with the cafe bobber style shocks i want perhaps a hardtail?? and spring seat, Pro/cons?
4. rake.....I really like the comfort of drag bars swept back and a more rake. degrees? fork lengths or cut and adjust stock?


The side note being i half stripped my bike to get to the engine and wanna dip the frame before i remount the new motor.  I feel i want to tear down the new(to me) motor since it has been sitting...but i trust its ready since it ran till it became mine.

Thanx in advance I cant wait to get pics up of the tear down, and get some photoshop pics up!!

If i were you i would start reading and researching as that rear is NOT a 180 {130 would be closer}and you will have no end of trouble with anything bigger than 150-160. I have seen twin cam hondas from the early eighties with 5 inch rims170-180} and they still had to do a fair bit of modifying to make it fit.

Now now we cannot judge. 

Fitting a 240 or 300 will be a lot of work. But making a hardtail with a sprung seat will be the easiest way to go. Be prepared to run a jackshaft.

It will be best to run your frame around your engine first and my suggestion will be to buy or build a frame jig for this amount of fabrication. Everything will be easier to make as well as straight. You don't want a crooked bike ya know?

The stock rear is a 130. Unless someone has already modified your bike.

Hope you get it sorted soon and get pics up.

They won't help him it's a DOHC. They are a strictly SOHC site. Many have tried.

I suppose if you "forget" to mention that it's a DOHC.....

I have a buddy who has plans to cafe his 1981 cb750C.  Sounds like you're going for a different look than him, but I'll be following your progress.

I'd avoid modding the rake angle of the steering head if you can,  perhaps you can achieve the look you want with some dogbone risers?
