Learn MoreKibblewhite intake valves are a great upgrade from your O.E.M. motorcycle valves due to their superior performance and outstanding reliability.
All KPMI Black Diamond stainless steel valves are impregnated by a special German process to a depth of 0.002", with a surface build up of 0.0002". 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 Kibblewhite's computerized flow bench. Black Diamond Valves are light, strong, one-piece forgings with profiles that provide excellent flow characteristics and will outlast titanium valves.
KPMI fully CNC machines their White Diamond Valves from a one-piece forging of either EV8 Stainless Steel or Inconel-751. These materials have proven heat and corrosion resistance properties. Each valve is designed using Finite Element Analysis software, and profiles are tested on computerized flow bench. Strict attention is paid to the surface preparation of the valves, and the purity of the chrome is closely monitored. A 360-degree anode is used to produce the highest possible grade of hard chrome finish. White Diamond Valves are light, strong, one-piece forgings with profiles that provide excellent flow characteristics.
Inconel is classified as a "Super Alloy," meaning that it is designed to survive under the most extreme temperatures and pressures, where other valves will begin to burn, corrode, or completely fail. This is the material of choice for high output engines running turbos, superchargers, nitromethane, or nitrous.
