Overview
Description
New Race head for 88cc (52mm) bore kits
- Larger valves (now25/22mm) and better flow for increased
performance. Also has bigger cooling fins. Includes all necessary parts and
comes assembled! - 52mm piston with rings, pin, & clips.
- High performance race camshaft (for the Race Head only)
- Head gasket kit.
- Intake kit for the race head – will match the race had much much better than intakes intended for the stock head.
This race head has been updated for even more performance! It now has 25/22mm valves with better porting/flow. We also kept the combustion chamber the same size and changed the angle of the valves slightly. This kit is for upgrading 88cc bore kits with a stock head to the Race head. You should have your existing cylinder honed (unless it's 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).
