What you did was burn the belt at one point and put the typical thin spot in it. you will feel this spot as a rythmic jerking in the drive train from zero to about 25 mph. On the higher HP ski-doo's this thin spot will actually cause pittting in the sheave face (looks like a quarter size divit made by a sand blaster) further out in the sheave where the belt would run at higher R's and speed. The belt is trying to suck into this thin spot every time it comes around and it is "exploded" back apart when it hits the thicker far side of the burned spot. This action can be pretty violent when you're cranking 8000 rpm. The result is a dead clutch, DO NOT RUN IT ANYMORE OR IT COULD EXPLODE! I've seen it happen. You need to inspect both sheaves for any sign of abnormal wear and replace them if you find any, you cannot fix this damage. The moral of the story is if you have a high power sled and you smoke a belt throw the belt away. I have seen this happen on sleds as low as 500 fan twins. I don't know if this is a problem with polaris,cat,yamahahaha type clutches, I'm more familiar with ski-doo. This damage is not always the result when a burned belt is used, it is pretty rare, but is does happen and it is something to be warry of. Sorry, but you have a repair bill.
