DS6-2 Dyna-S ignition module. Single fire

This Dynatek Dyna-S ignition module is specifically designed for single-fire applications, providing a more efficient spark by firing only the cylinder on the compression stroke. It comes complete with a rotor and fits 1970 to 1999 Big Twin models, excluding Twin Cams, and 1971 to 2003 Sportsters. This module is compatible with both single and dual-plugged heads, though it requires a separate mechanical advance unit for operation. For street applications, I recommend using a 5-ohm Dyna coil, while a 3-ohm coil is better suited for racing. Sold individually, this module is a great way to reduce engine vibration and potentially increase power on your classic Harley-Davidson.
