Dyna S Ignition System 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.
The venerable Dyna S ignition System is a time proven solution to the basic ignition needs of the vintage muscle bike. As a stand alone ignition the Dyna S is the standard of performance and reliability.
