Dynatek Dyna S Ignition System.

The Dyna S is a complete self-contained electronic ignition system built with the latest state-of-the-art engineering. This is the same ignition used by top racers over the past 2 decades. The Dyna S is completely housed behind the ignition cover and uses a magnetic rotor with the original spark advancer, so the factory advance curve is maintained. Increases power and reduces vibration, backfiring and intake reversion, especially on engines with radical cam timing. Front and rear cylinder timing may be set individually. Perfect for hot dual-plugged engines.

The Dyna S ignition is a time proven solution to the basic ignition and trigger needs of the modern motorcycle. The Dyna S is the standard of performance and reliability. Very high quality made in the USA.

This ignition can be used with your stock coils or any other coils 3 ohms or higher. Includes instructions and comes with a one year warranty through Dynatek.
