Features:

Aluminum cylinder head and iron cylinder body: Improves the heat dissipation capability, cuts the weight and increases the torque of the engine.

Crank shaft: The engine is low speed with high torque and has large diameter bearings for crankshaft connecting rod, increasing the reliability of the bearings.

Air-cooled engine: There are metal fins covering the outside of the cylinders and the heat generated by the engine is released directly into the air when the cooling fan blows air over fins. It has the advantages of simple structure, light weight, wide adaptability to climate change, rapid start up and no need of radiator.

High-flow oil pump: Reduces the wear of friction pairs and prolongs the engine life.

Had a difficult time installing this engine in my go kart. Once installed and finally running we used it for only 3 weeks on and off. Engine started cutting out, then the transmission wouldn't shift. Soon after, the engine died and I can't get it out of 2nd gear. Very cheap engine and is not worth the time spent trying to get it to work.
