hi i have a 92 exciter 570 it was working poerfectly but i looked at my belt and it was so britle it cracked when i bend it so i had a new kimpex belt here so i put it on and went for a ride whenever i hit powder or any snow touched the belt instant slip well i think its slipping casue the sled just revs and barely moves and i can smell hot belt. so i put the old crunchy belt back on worked great. so i talked to someone they said maybe the secondary isnt set up right take out a shim and see if it grabs better so i did and nothing so i just road all season on the bad belt. so now its winter again so i bought a new belt from yamaha and same thing now. hit snow just rev barely moves. my primary spins and the belt will spin but the slep just creeps forward. any ideas if im on the road it works perfectly. would it be my secondary maybe. and what should i look for.
