so heres the deal, my 1997 Polaris Sportsman 500 used to do 60mph and could spin tires like nothing, because the power was there. lately it hasn't had that power, and i took it to the dealer and they looked at the carb and clutch, they put a few things in but still no good. so i took it there again and they said the cam is gone. sometimes when i first get on and drive it it will go 45mph but it still has no balls, then it will suddenly only go 20mph and it doesn't seem to rev high enough. does this sound like a cam problem, because i heard these quads are known for bad exhaust lobes?
