This Black Diamond process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating. Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. Black Diamond Valves are lightweight, strong, one-piece forgings with profiles that provide excellent flow characteristics

The KPM high-performance dual valve springs were specially designed for MPS by Kibblewhite Performance Machining. Designed for all popular cam profiles, these springs were computer simulated with extra attention paid to mass, rpm, harmonics, and stress evaluations to provide the best valve spring for your Hayabusa. They produce 65 pounds of seat pressure at 1.450” installed height and will not coil bind with cams up to .490 lift. KPM Hayabusa Valve Springs are made with premium grade super clean chrome silicon wire and are heat treated, shot peened, and stress relieved.
