Cylinder head porting

Call for Price

After many requests we have decided to standardize a cylinder head porting "package" for the RC51.  The price is $849.95 which includes the porting and competition valve job. (using stock valves)   This is not a simple "port and polish job."   The porting we offer has been developed on the flowbench *and* dyno.  We make fairly big changes to the intake ports in terms of shape and size.  (despite what you may read on some sites about small intake ports being good, the RC's ports are in fact too small)  The RC's ports are fairly good for a production bike but we have seen gains of 5-7hp with the porting we offer.
