Larger valves (now 25/22mm) and better flow for increased performance. Also has bigger cooling fins. Includes all necessary parts and comes assembled!
52mm piston with rings, pin, & clips.

This kit is for upgrading 88cc bore kits with a stock head to the Race head. You should have your existing cylinder honed (unless its new) prior to installing this kit. We recommend purchasing a high volume oil pump kit.
Installation Note: It will save a lot of time and effort if the oil pump is installed while installing the bore kit (requires cylinder removal).
