It sounds like the engine is revving higher but i do not increase in speed. what might be the problem? my bike wont go faster then 75 mph. Feels like a drag, RPM increases but bike speed slowly increases. This problem comes and goes, when it is gone, the bike runs great, very fast and picks up speed quickly. When the problem starts, the motor revs nicely but when RPM increases, the sound changes and the pick up speed is slow, like dragging. The problem is occurring more frequently, on way home from work, as I was accelerating on freeway, the problem started. I took bike out later that night and the problem was still there at first, then it went away and bike ran great. Ran good for two days to and from work, then occurred again on way home from work. Next morning the problem still occurred on way to work, about 3/4 way to work, the problem stopped and bike is running great again.

Any idea on what could be the problem?
