Valve Black Diamond™ by KIBBLEWHITE (manufacturer part number: 20-4195): a monoblock exhaust valve designed for vintage/classic projects and road/touring applications. Made from stainless steel with a Stellite tip, it combines lightweight construction and optimised flow profiles for reliable operation and delayed wear in demanding configurations.
Ideal for restorations and modifications on 1980s Harley twin-cylinder models — such as the FXWG 1340 Wide Glide, FXS 1340 Low Rider, and FXR 1340 Super Glide II — this valve offers durability and longevity without overstating technical promises. Suitable for riders concerned about the reliability and longevity of the valve train.
