Kawasaki Ultra 250, 260, 300, 310, 15F, SXR, Ultra LX Valve Train Upgrade

(After countless hours of R&D, and tons of testing, KP is proud to introduce our fine tuned racing spring kit! This kit was designed for the daily driver and also the racer in mind. These springs deliver the optimal seat pressure the Ultra cylinder heads need. These springs are 56 pounds at the seat and 171 at full lift. Full lift is 0.385". Kawasaki valves are well known for dropping, almost always from inadequate spring pressure. Stock springs can over rev and float as early as 7000 RPM! The additional pressure keeps these valves synchronized precisely to the beat of the engine at any given RPM up to 9,000 RPM. We are extremely pleased with this kit, and we know you will be also! For 15F/SXR/Ultra LX, please choose 250/260 upgrade kit.
