I recently purchased a 96 rmx 250. it starts good rides good but all the power is right off idle. Past half to three quarters throttle it just falls on its face. Have been told it needs a different exhaust but the only ones i can find for this year bike are for low end power. Anyone know of an rm pipe that would fit it or a good rmx pipe with good top end? Anyone else had this experience? Any & all help would be greatly appreciated. Thanx
