Kawasaki Ultra 250 260 300 310 ECU Tune

(ECU tunes can be customized for an additional fee. The stock machine is not rated for much more than 8,000 RPM. When you exceed this RPM, you are more likely to experience valve float. Which is something you do not want. Minimally, if you would like to consistently rev over 7,800 we recommend our upgraded valve springs. Otherwise, it is best to stay below for safety sake. Please choose from the tunes below. All of our standard tunes are optimized for 93 octane pump gas, racing tunes are for 110 Octane pump gas or E-85 only. 300/310 tunes come standard with traction control and speed control deactivated. Stage 3 tunes are optimized for 93 octane gasoline. For lower octane tunes, this would be custom. Tunes are available for 15F/ LX/ SXR/ STX 160 models. Please inquire.)
