Setup, Compatibility & Care

Before installation, ensure your engine is a 47cc or 49cc pocket bike variant and that you have a type 3 easystart pullstart mechanism. To install, remove the engine shroud, loosen the existing flywheel nut, and use a suitable flywheel puller to remove the old unit. Clean the crankshaft taper of any oil or debris before seating the new flywheel. Tighten the included bolt to the manufacturer's torque specification to prevent the unit from loosening during operation. To maintain, periodically check the bolt tightness after the initial "break-in" period to account for thermal expansion and vibration settlement.
