comet used to make them back in like the '70s. they came up with the tav system and dropped it. they only have one sprocket that is replaceable, and only in one size. not exactly a racing part

You can set them up to be very adjustable.

i have one. how do u set so it can be very adjustable?

 

[mike75925]

you can set any thing up to be adjustable. how much time and money do you want to spend?

They still make 2 speed jackshafts. Just by changing the springs you can adjust it.

Different clutch springs=different shift points.

that must be a pain to switch those springs. springs are cheap though
