It was a sorta botched transplant when I bought it. It had the original clutch from ski-doo, but I didn't have to modify anything (was just a bit tough to get the bolt out). I bought a replacement comet clutch which also fits pretty well. I also bought and had a stock rotax exhaust shortened and shoved under the body and added a cheap, small muffler after it. It's still pretty loud. It works okay, but I haven't ridden it much in the past few yrs.
