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).
See the Performance Info section for additional
information on our performance parts.
