jtervaniemi,

I took some measurements and a polaris jackshaft is 24 inches long and the kawi is 26 3/4"   I don't see that a polaris jackshaft is going to work in Kawi.  What am I missing?

Hi
There was no problem for me, I don't remember the measurements on the shaft I used.
The clutch is floating on the shaft, self centering.

Mid 90's Polaris jack shafts are over 26". I talked with another racer last night he said 26.625" is a standard Indy jack shaft Polaris made different sizes over the years so measure before you buy one to make sure it fits your Application.

I bought a polaris jackshaft from 97 XC700 for $25 off ebay.  see attached pic.  It looks like it will work.  The pic shows side by side with Kawi jackshaft.  the Polaris is shorter by 5/8" but I can simply add a larger spacer on the secondary side.  It already has standard 1/2" spacer.  The gear fits on fine and looks like the brake disc I bought of ebay for polaris will work as well.
