Description
Factory valve kits deteriorate from heat cycling and fuel exposure, leading to reduced compression and power loss over time. The KIBBLEWHITE Complete Valve Kit restores your Evolution/883’s combustion efficiency with precision-engineered components that withstand sustained high-RPM operation. This U.S.-made kit eliminates the need to source individual valves, springs, and seals separately—everything you need for a complete top-end refresh comes in one box.
