not sure why there is all the talk about ski doo coming with a new belt, ya they did but we had a clutch apart from a 08 summit x154 last night and the arm pins were all full of the sticky crap and the arms were very tight! same problem as last years clutchs so why dont they just fix that first? oh and by the way we did have one of the new belts to put on it too, hope it works just wish ski doo would have done some warrenty of belts for me last year on my 07 x but that a different story i guess to ski doo
