I have a xlt600 with an aerocharger turbo, sled has been sitting for 3 years, the problems I'm having is that it seems like I'm using an excessive amount of throttle for the speed I'm going, the sled don't have much power at the moment, and it seems like when the sled has extra strain on it, such as going up a decent size hill or deep snow, the power just cuts right out, but not a bogging sound, could these problems occur if my clutch is messed up or carb is dirty/ out of tune
