[Chop2007]

Hello everyone. I'm new to the forum and to custom chops. I just recently purchased a custom chopper that has a 110 revtech motor with a 6 speed transmission. The bike is missing the jackshaft bolt and im not sure which kit I should buy. Anyone have any advise? Thanks in advanced

There are 2 possibilities,, the only way to positively know,, is to check the threads in the center of the starter drive shaft... which generally requires the starter be in hand.

One is 10-24 threads, the other is 1/4"×20 threads there is/was a bolt available that adapted the 1/4" bolt to the 10-24 thread..

I found the 10-24 bolt to be shorter so to keep the length I machined the 1/4 -20 down and threaded it to 10-24.
It seemed the short bolt only caught a limited number of threads.

Thanks. I also have another issue I forgot to mention. Any idea on how to figure out what tooth count I need for the gear? I seen some was 10 tooth and some 9 tooth

Hopefully I won't have that issue. I dont have the tools to do that kind of work.

Count the teeth on the clutch baskets ring gear, then with that info you can find what pinion gear is needed to match
