Dyna S Ignition

The Dyna ”S” is a high performance ignition system that installs into any Big Twin 1970-1999 or Sportster 1971-2003 cam cover. It features a magnetic rotor (sender) in combination with base plate mounted receiver. Models equipped with factory electronic ignition systems require a complete advance unit assembly.

Available as dual fire - both cylinders fire at the same time (like stock) - or single fire, i.e. each cylinder fires individually at the end of its compression stroke.

Street use with 5 Ohm coils only! 3 Ohm coils for race only! Do not use with WW 12-225!

Tach-Adaptor must be used whenever a Dyna S Single Fire ignition system is installed on a H-D with electronic tachometer. WW# 12-518 works with most tachs on the market. Some exceptions require WW 12-519 (T103). In this case we refund the non-compatible adaptor.
