Dyna S Ignition Advance Flyweight Assembly (Harley Shovelhead)
Excellent condition.
This flyweight assembly is manufactured by Dynatek for the Dyna S ignition kits for Big Twin cone motors from 1970-99. It will work for both single and two pole rotors. And although this assembly can be used to replace stock units, the spring tension on this assembly is a bit stronger. So the advance spring set selected for this assembly was designed for the Dyna S electronic ignition sensors.
