You did not mention whether or not you have a pipe on it, but bone stock KDX's are a bit flat on the top end without one. You can pull the small slotted cover off of the left side of the motor, and rev the bike, to see if the power valve system is moving or not.

check your kips to see if there working. as greg said.......the stock pipe on mine blubbers a little when you first get on the trottle.

it as full fmf system dnt no witch 1 i will pull the kips cover and see if its workin thanks guys
