SSP-G Crankcase 67mm 232cc 4V Big Bore Power Kit w/Crankshaft (GY6 longcase)

Description: SSP-G Crankcase 67mm 232cc 4V Big Bore Power Kit w/Crankshaft for upgrade GY6 125/150cc 4-stroke longcase engines. This complete power kit comes with a 67mm cylinder kit and a matching crankcase. This means there is no machining of the crankcase required! The crankcase is also pre-drilled and tapped for an oil cooler, which is a necessity on street-ridden bikes. An oil block-off fitting is included for race bikes. The manufacturer suggests up to 25hp at 10,800 RPM is possible with this kit. Some recommended additions (not included with kit) are a high torque starter and starter clutch, an oil cooler kit for street riding, a high quality (such as Bando) 842-20-30 belt, 34mm PWK carburetor, quick throttle, rear gears, and a performance clutch and variator kit.
