i traded for this atv and it had a bad miss .i have unhooked the tors and the parking brake sensor with no help and it still misses after cleaning carb .they rebuilt the engine but i dont know if they used new gaskets will a air leak cause my promblem it is very noticeable in gear.it does not seem to have alot of power and it is like it has a sputter or like a rev limiter is kicking in before it is supposed to .plese help i would like to ride.
