Hi - picked up a bike already assembled with a Skyhawk 66cc motor - runs pretty well, revs nicely with the clutch in but won't go over 20 mph or so, not even down steep hills. The low-end acceleration is fine and at any time I can pull the clutch in and high-rev the motor, but when it's engaged (even downhill) the motor will only rev to a certain speed and will actually slow the bike to around 20 mph from a much faster coasting speed.
Seems kind of strange - I'm told these motorized bikes don't have speed limiters....
Anyone know what could cause this?
