piston rings, cylinder for chinese ATV
 

piston is 49.6 mm
Skirt is 44.25 mm
Bore is 50 mm
Bore length is 69 mm (crank base to head)

Anyone who can help direct me where to find this would be awesome. VMC did not have anything that would work.

Post a link showing the engine.

Typical 50mm is for 100cc

Piston spec can find via http://www.jhpiston.com/about_can/

Barrel kit for Win 100 & clones should be something as https://item.taobao.com/item.htm?id=35713153747

There should be a number on the engine that will give the engines model number. That will go along way to finding the correct parts.
