I have a old kt100 with an old horstman clutch and 3rd bearing I just bought for my crg kt1 and I cant seem to line it up on the kart. The sprocket on the engine is to the inside of the clutch and when I try to put on the chain the axle sprocket contacts the rear right bearing mount. My question is what mount clutch or 3rd bearing setup are you running on crg and how do I know if it’s long or short shaft. And where can I find an engine manual.
