Important Fitment Information
Motorized bicycle engines can vary even when advertised with the same displacement. Before ordering, compare the listed dimensions, 45 mm mounting-hole spacing, combustion-chamber design, spark-plug thread, and gasket pattern with your existing cylinder head.
Installation hardware and spark plug are not included. Professional installation is recommended, and the cylinder-head fasteners should be tightened evenly to the engine manufacturer’s specified torque.
