RZ 500 cylinder head machined to GPL Racing spec.
All cylinder head machining is done off the bolt hole pattern, and not done by clocking the combustion casting. As with all Yamaha cast cylinder heads, the combustion chamber and squish band are not central to the bolt pattern, so this will bring the squish band central to the bolt pattern.
This service is available for $250 Cad, plus shipping for the two cylinder heads to be machined to a GPL Racing spec.
