NCY Cylinder Head 58.5mm 2V Fit 54mm (GY6)

Description: NCY Cylinder Head 58.5mm Wear-Resisting 2 valves with larger intake/exhaust ports will allow your GY6 125/150cc+ 2-Valve Cylinder to breathe better! Also, works for Buddy 125cc when used in conjunction with NCY Cylinder 58.5mm 161cc Big Bore Kit (Part# 1100-1287).

NCY Cylinder Head 10mm diameter head allows for extra clearance between your wrench and the head for easy access. When changing a cylinder kit or an exhaust, it's a clever idea to pick up a few extra 8mm Studs, since these can easily need replacing and bring your project to a grinding halt while you wait. These nuts are essential.
