		Lightweight Racing Valve Spring Kits for Honda® CRF™ 250R 2008-2009 KPMI takes a scientific “System” approach when designing our Valve spring kits. Each component is designed to work with the others as part of the complete system. KPMI’s engineers use our proprietary design and simulation softwares, and draw on our 70+ years of design experience to create these systems. Our design, simulation, and manufacturing processes insure compatibility of the valve spring’s force and natural frequency with the cam profile, valvetrain mass, system harmonics, and the engine RPM. Our spring manufacturing partners are U.S based companies that are ISO certified. The Super-Clean Chrome Silicon valve spring wire we use is traceable back to Kobe Japan where some of the best spring wire in the ...

		Intake Only Valve Spring Kits for Honda® CRF™ 250R 2008-2009 These kits can extend the life expectancy of the intake valves by 3 times over the stock titanium valves. KPMI`s Intake Only Kits have been designed as a stainless steel valve conversion system to replace factory titanium intake valves and components. KPMI’s engineers use our proprietary design and simulation softwares to create these systems. Our design, simulation, and manufacturing processes insure compatibility of the valve spring’s force and natural frequency with the cam profile, the mass of the system, and the engine RPM. Literally thousands of riders have converted to these kits to extend the life of of their intake valves.




		Tensilite® Valves for Honda® CRF™ 250R 2008-2009 (4) All KPMI titanium valves are manufactured from solid U.S. milled titanium bar. The titanium bar is cut, forged and then the stem is pulled from the forging process and cross-sectionally reduced. After all final grinding and machining the valve is encased in a hard titanium nitride shell. We have tested these valves in the lab and on the track. They have proven themselves time after time in many high-demand applications, from a dual stage nitrous motor to a recent "Superbike from Hell".




		Black Diamond™ Valves for Honda® CRF™ 250R 2008-2009 (4) All KPMI Black Diamond™ stainless steel valves are impregnated by a special German process to a depth of .002”, with a surface build up of .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 our computerized flow bench. Black Diamond™ Valves are light, strong, one piece forgings with profiles that provide excellent flow characteristics.




		Valve Guides for Honda® CRF™ 250R 2008-2009 (10) We choose to use C63000 nickel bronze as a material to make valve guides because of its ideal characteristics for the application. The 4-5 percent nickel content produces superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity.




		Valve Guide Seals for Honda® CRF™ 250R 2008-2009 We choose to use C63000 nickel bronze as a material to make valve guides because of its ideal characteristics for the application. The 4-5 percent nickel content produces superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity.
