I have a sled that used to be turboed, and has a 01 800 polaris primary on it. I finally have the motor running half decent again, but now I'm only using half the clutch sheave (not fully engaging). I tried a weaker spring and it only helped a little. I'd like to buy a stock Yami RX-1 clutch which I know how to set up but can't find one. I'm not sure how to make this thing work without endless trial and error and dumping money into parts.
