YZ250f 2nd Injector Kit : Includes a GYTR air boot made to fit the YZ250f. Injector,fuel line are all mounted and ready to install in the air boot. The YZ250f has a great power plant stock and has given us a great platform to make a ultra competitive package for our customers. By mounting the 2nd injector farther away from the throttle body we have seen a great increase in power and torque in the mid-higher rpm range same as Kawasaki saw with their KX250f. We have developed and track tested this kit and are finally ready to release it to the public. (This kit has been developed and will include a Vortex ecu with mapping to control the 2nd injector) Twin air filter and air box not included.
