had the sled out last weekend , was running great just ditch riding, all of the sudden the belt blew, got all the pieces , string whatever else out of the clutches , put my spare belt back on , and it would pull hard to 7600 rpm , backfire through the exhaust and not rev any higher , so rode it nice to get home, checked belt deflection that was good, got it back in the city and tried to figure out what was wrong with it , changed spark plugs - no difference, checked reeds - good , tried diferent knock sensor - no difference , checked stator with ohm meter - good , checked primary over good , weights, rollers ,nothing binding springs good , changed secondary rollers , spring , cleaned everything out , checked power valves - good , servo motor working properly , I did find on the 3 wire connection from the stator to the sled the one yellow had gotten hot and melted so I direct connected those 3 wires instead of the block being there took it out on the grass with what little snow we have , still revs to 8200 and starts to backfire through the exhaust and surge , the only thing weird I have noticed and not had a chance to look into is the diamond drive has ALOT of play in it when just sitting on the floor I can move the clutch quite a bit , I don't think it could cause the sled to do this ,has anyone ever heard of anything like this im stumped ..
