CRF 50 Race Head for 88cc Kit

***NEW**Race head for 88cc (52mm) bore kits

- NEW Race Head – 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. 
- 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.

6/26/06 Our 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 its new) prior to installing this kit. 

We recommend purchasing a high volume oil pump kit (available in this section). 

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).
