NCY Power & Speed 52mm Big Bore Cylinder & 50mm Big Valve Head, GY6 Scooter

Description

ITEM DESCRIPTION:
NCY Power & Speed 52mm Big Bore Cylinder &
Big Valve Head for GY6 50 engine (Made in Taiwan).
NOTE:
The head
has 23mm intake & 20mm exhaust valves.
NOTE:
Currently the big valve head is only available with Non-EGR head & 64mm long valves.
NOTE:
The 52mm big bore cylinder is commonly called 110cc or 120cc but it will give an actual displacement of 88cc. This is a deceptive practice (all I can do is warn my customers).
GY6 Engine Specs (below):
Notice the stated displacement compared to the actual displacement (They're deceptively rounded... please be aware of it).
