Exhaust Valve Standard Triumph 650 / 750 1963-83

Exhaust Valve, standard size, sold individually. Replacement for OEM # 70-2904 Kibblewhite produces world-class components here in the USA which are found on everything from vintage street bikes to Larry ‘Spiderman’ McBride’s Top Fuel World Champion drag bike and Alp Sungurtekin’s world-recording holding 175mph 650cc Triumph land speed racer. In Kibblewhite’s own words: These OEM style replacement valves exceed the material and tolerance specs of the original factory pieces. The valves are one piece stainless steel forgings. They are fully CNC machined with swirl polished tulip profiles. Stellite has been welded on to the tips to resist the deformation that can be caused by the impact of the rocker arm.
