    New 32 tooth sprocket limiting rpm

    With my 44 tooth the engine would sound like its going crazy at max speed.. After I installed new 32 tooth sprocket.. My max rpm is really slow.. It is like it hit a wall at half rpm the 44 tooth had on flat.. Not sure y.. Any thoughts?.. I can get up slight hills with no pedaling with the 32 tooth
