If you are looking for a really really nice 63mm 190cc big bore kit for your GY6 A (54mm stud spacing), this is the ticket! This is a forged piston with a ceramic coated cylinder to keep it cool. We definitely recommend an oil cooler for this set up. Be sure to add the 3.5mm stroker crank. This Kit is designed specifically for the 3.5mm crank.

IMPORTANT NOTE: Your engine cases will need to be bored out. This is not a drop in kit. You will need this tool CLICK HERE. In order to bore the cases, the crank shaft has to be removed. Definitely add a high volume oil pump to this set up CLICK HERE.
