Default Re: Rack mounting a chinagirl

The only issue I see using a four stroke would be the lack of a gear reduction. This would require a much larger rear sprocket to work correctly, but I see no reason any engine could not be used.
I decided to use a pocketbike pipe rather than the stock muffler so I won't have to do it again later.




Still need to build a fuel tank stand and hook up the throttle and clutch cables.
Might need to jack up the spring preload as well to prevent the seatpost hitting the motor. Seems a bit soft as is...

Throttle and clutch mounted and ran cables. Little bit short but still workable. No pulling or binding when turning the bars any normal amount.

Still need to fab tank stand and find a front tire and tube before testing begins.
Too cold and wet for any fab work today. My hands hurting too bad from the cold.

Great work Maniac That is a very nice set up, I'll be eagerly waiting the first road test report once the weather improves.

Now I'm starting to wonder how a China Girl would work out mounted over the front wheel of a bike

From what I can see I.W., this same style mounting would work just as well over the front wheel. Just be sure the road is dry and the front wheel is straight when bump starting.
A good solid rack would be easy to build....sprocket does not care what wheel it's bolted to.
By the way.....I believe this would also work quite well to mount a ht on the Walmart Mongoose fatbike! No jackshaft reqired! Just possibly a sprocket adapter or some type of spacer for the ragjoint sprocket.

Now Labrat or Josh Moon or one of our other clinically insane members will probably build a two wheel drive Rokon tribute bicycle....

I would NEVER do something so outrageous!
I'm shocked and appalled you could think me capable of such a heinous act!

Did a bit more today. Built a tank stand and mounted the tank.
Unfortunately, I started feeling quite poor and did not get around to mounting a front tire and testing the setup.
Tomorrow hopefully.
