KPMI 2014-2016 YAMAHA YZ450F INTAKE VALVE/SPRING KIT STAINLESS STEEL 80-81100

Stainless Steel Intake Valve Conversion Kits (Intake Only Kits)

These kits can extend the life expectancy of the intake valves by 3 times over the stock 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 their intake valves.

FOOT NOTE: § = Use OEM Valve Stem Seals
