For riders looking to improve the efficiency and longevity of their engine, Kibblewhite Black Diamond valves offer a significant step up from stock. These one-piece valves are machined from premium stainless steel and treated with a proprietary process that penetrates the metal .002" deep. This treatment creates a surface that is harder and slicker than traditional plating, reducing friction and protecting against premature wear and corrosion. They are specifically designed to fit Sportster, Buell RS, Single, Tube frame, and XB models, providing the flow characteristics needed for high-performance applications. These valves are a direct high-performance replacement for OEM 18024-87. Whether you're building a race-ready Buell or a reliable street Sportster, these lightweight, durable valves ensure your top end stays tight and efficient for thousands of miles.
