R&D offers High Performance Racing Valves that are designed to be lighter, stronger, and most importantly, outflow stock O.E.M. valves. R&D valves will flow 1.5 CFM more over stock valves with R&Ds race proven back cut seats and high flow undercut stems. Each R&D Valve is a one piece forged design from only the highest grades of Stainless and Inconel materials with a 52 HRC hardened valve stem tip for maximum strength. Valves are black nitrite coated for superior wear surface hardness and will fight against carbon buildup. When building any 4 stroke race engine, there should be three questions! How light, how strong, and how much more power! R&D Racing Valves answer those questions and more, as well as deliver a measurable power gain! R&D Valves are available in standard and 1mm oversize! At R&D, we have been there and tested that. There are only two choices of valves we recommend that work reliably in Kawasaki engines, O.E.M. Kawasaki stock valves, or the R&D Racing Valves. R&D Valves install with O.E.M. Valve locks which have proven to be the best valve locks. NOTE: R&D also offers Titanium Intake Valves.
