Review on Enhance Performance with CDHPOWER YD100 Bottom End Crank Assembly for Gas Motorized Bicycle Engine Kit by Omar Thorndike

Fixed my engine runs fine. My last one blew out when the clutch was getting too bad without proper adjustment from the factory when I bought the whole set. I learned a lot, but it worked. All I can say is get the clutch set up properly and never expose the inner dry clutch plates and facings to grease/oil. and do not remove the coupling nut. $100 to end my frustration was worth it working 2x better than before. cdh power is a great product
