Sellers of Lifan engines often supply everything you need as a kit. Engine, carb, manifold, CDI, rectifier/regulator, coil, kick start lever, shift lever, etc.. I've bought 3 engines this way and installed them in old Hondas. Makes it real easy. Wiring was straight forward and jetting in the supplied carbs was perfect.

It is much easier to start with a running bike than to figure out why it won't start when getting just an engine.
Lifan and several others have excellent reviews of their engines.
