GY6 50 52mm BBK

NCY Big Bore Kit for GY6 50 @ 52mm

Special Order Only

Includes Cylinder Kit with Piston and Rings at 52mm

Also Includes a 52mm Cylinder Head with Larger Valves

Stock engines have either 63 or 64mm valve stems. If you have a problem with valves not working with you rocker arm assembly replace rocker arm assembly and not valves. The valves in the NCY Head are larger than most other heads being sold and are a true 52mm to match the 52mm cylinder kit.

Be careful so many folks are buying the cheap so called 100cc kit and burning up their engines.

Air and Fuel should also be upgraded as well as exhaust.
