Performance Setups

Our Performance Setups are higher performance than our Trail setups with a broader spread of power. They suit everyone from the average trail rider through to serious racers. These builds basically maximise the potential of the stock engine design without changing the stock port layout. There’s no loss of reliability from stock but there are big gains in power!

These setups use the same great head designs combined with our Standard Cylinder Porting to improve power throughout the rpm range by making the absolute most of the stock cylinder design. All casting flaws are removed, the cylinder base is matched to the base gasket and cases, the intake and exhaust ducts are smoothed and shaped, the port windows are carefully cleaned up and the powervalve components matched to the exhaust duct. Depending upon the power delivery required these setups may also involve machining the cylinder base to get the ports in the right spot or the use of epoxy to increase bottom end and throttle response. There is virtually no risk to reliability with these packages and the gains are very noticeable.
