About This Product
Kibblewhite’s Black Diamond high-performance valves are a significant upgrade for any Single, Sportster, Tube frame, or XB model. These one-piece valves are machined from premium stainless steel and profiled for superior flow. What sets them apart is the specialized impregnation process that builds up the surface by .002 inches, drastically reducing friction and improving wear resistance compared to traditional chrome plating. They are lightweight and highly resistant to corrosion, making them ideal for high-performance builds. This specific valve is a direct replacement for OEM 18690-02 and is perfect for mechanics looking to squeeze more efficiency and longevity out of their engine while maintaining strict tolerances.
