6.00mm Conversion System
For all out 650 Triumph® race engines KPMI® offers our new ultra light 6.0mm valve stem conversion kits and components. Our new spring kit features a Beehive spring wound with Super Clean Chrome Silicon ovate spring wire that has been heat treated and shot peened, FEA designed lightweight heat treated steel retainers, and fully machined heat treated steel keepers and basewashers. KPMI® C630 bronze guides allow for high lift and tight clearances. Valves are available in either our stainless steel one piece forged Black Diamond series, or one piece forged Tensilite® Titanium series.
