- Again, you should consult the engine builder or tuner for advice on your application. Incorrect timing advance rates and RPM limit can result in severe engine damage. If attempting yourself, make only small changes and monitor performance carefully. On high compression motors, do not be afraid to try reducing the total timing for the best performance
Note- All programmable dirt bike ignitions require a programming kit (P/N DIPK-6) for timing curve and RPM limit change.
