Dynatek Dyna S Ignition System – Dual Fire (DS6-1)

Part #: DS6-1 | Manufacturer: Dynatek | Category: IgnitionPoints and condensers are old technology — and they fail at the worst times. The Dynatek Dyna S Ignition System replaces your stock ignition points with a self-contained electronic unit, giving carbureted Harley-Davidson models from 1970-2003 a cleaner, more consistent spark without the maintenance headaches of a points-based system.This Dual Fire version fires both cylinders simultaneously and mounts completely behind your factory ignition cover, so there's no bulky external box to find a home for. It uses a magnetic rotor paired with your original spark advancer, which means your bike keeps its factory advance curve — no retuning or guesswork required.

Why riders upgrade to Dyna S:

Eliminates points and condensers, along with the wear, pitting, and constant gap adjustments that come with them
Hall Effect magnetic sensors stay accurate regardless of RPM, dirt, or oil exposure — points can't compete with that kind of consistency
Improves spark timing and extends spark plug life over stock ignition setups
Fully enclosed design keeps it protected and out of the way
Retains the factory advance curve, so your bike runs true to spec

Fitment note: This ignition system is designed for 1970-2003 carbureted Harley-Davidson Big Twin and Sportster models with points-style ignition. It requires an aftermarket 5-ohm coil or a stock points coil from early Shovelheads — it is not recommended for use with OEM coils. Certain later-model fitments (1984-1999 Big Twins, 1986-2003 XL models) also require a separate mechanical advance unit, sold separately. Always confirm compatibility with your exact year and model before ordering.Built in the U.S.A. by Dynatek, a name trusted in motorcycle ignition systems for decades, the Dyna S gives you factory-style reliability with the durability of modern electronics — one less thing to worry about on the road.
