check out some clutch kits for your sled. I don't know of any skidoo performance companies because i ride arctic cat. Hit up ebay for some and do a search on google or metacrawler or something. I'll keep my eyes open.
Same here...did you try hardcoresledder.com or amsnow.com? I know the Ski-doo's are different from the other clutches on the other brands. You have spring setting in the front and rear where as most others only have a rear spring setting. I would try the above sites for info, there is alot more technical info on there at this point.
