If your "bogging" in the later rpm then your lean. An easy way to tell the difference between a lean/rich "bog" is to stay in the throttle and see what bike tries to do. If it wants to die, chances are your lean. If it stutters and carries on then your probably rich. If motor passed leak down, and float height is proper, richen the needles and take for a rip. Ive seen great motor setup run like complete dog shit simpley because people worry about the pilot and main WAY to much and completely over look the needle/clip position.
