Building a Chopper: Seeking Expert Advice on Transmission Mounting

[sheldon]

I am building a custom chopper, hardtail frame. I am learning as I go and I had a video to help me but my vcr ate it. Does anybody know about transmission mounting or anything about bikes?

I know a little, but nothing about choppers. I thought most Engines had the tranny built in. I don't know much about HD components though.


I've been wanting to do a chopper myself someday, but use a Hyabusa engine.

Uhm, let me ask my bro about that and I'll get back to ya. He's put a good bit of time into them.

I have a set of Chopper Frame and Jig plans for sale. 7 plans. All dimensions and angles are included. I put a page on my welding website so I didn’t clutter up the forum.

Email me if you want more info.

Thanks a lot!

you could always look at another frame at a custom motorcycle shop, or any HD dealership for that matter. if you had the time, you could completely gut the trans case, bolt the mounting plate to it, and bolt it to the inside of the primary and bolt that to the engine. That would align your primary drive, and then all you would have to do is make sure that your secondary belt is aligned. Then tack the mount in place, check your measurements again and weld. Just make sure that the mount is mounted level, and inline, I helped my friend put in his engine mount (which is basically the oppsite way) and we had huge headaches the first time we tried because we didn't make sure it was square in the frame, and the outside primary cover would not fit.
