Stage 3 Performance Kit for the Honda GX390, Predator 420, and many 13HP Clone engines. The matched components in this kit will wake up your engine and allow you to remove the governor safely

The included billet flywheel will not work with the Honda UT2 rev limiting coil. Use OMB part number 425325 coil if you have the UT2 style coil.

This flywheel works with the electric starter on the engine and the recoil starter.
