alrighty, how can u tell if ur blower belt is slipping, heres what i got, i get on, blower winds up, but arount 580 the exhuast note started taking a drastict change in sound today? Is that belt slippage, i dont see any dust yet, but i got a whole quack of problems showin up all the sudden, thank good ness warrantie runs out in 3 weeks, and not yesterday tho...so what u think is that change in exhuast note slippage or not, may i add that when im at that rmp with out the blower theres no change in note
