Dynatek High-Performance Ignition System For Harley 1970-2003

Dynatek High-Performance Ignition System: Precision Timing for Classic & Modern V-Twins

The Dynatek High-Performance Ignition System is a professional-grade solution for Harley-Davidson owners looking to unlock the full potential of their 1970–2003 machines. For decades, Dynatek has been the industry leader in V-Twin electronics, and this system continues that legacy by providing a completely digital, high-energy spark that outclasses factory equipment. Whether you’re running a classic Shovelhead, a reliable Evolution, or a high-strung Sportster, this ignition system delivers the accuracy and power required for peak performance.

Eliminate Mechanical Weak Points

Traditional ignition systems rely on mechanical advance weights and springs that wear out over time, leading to erratic timing and power loss. The Dynatek system replaces these antiquated components with a fully digital advance map. By utilizing solid-state sensors and a high-speed microprocessor, the system calculates the perfect spark timing hundreds of times per second. This results in a smoother idle, crisper throttle response, and more consistent power delivery across the entire RPM range.

Customizable Advance Curves and Rev Control

One size does not fit all in the world of V-Twin performance. This high-performance kit features selectable advance curves, allowing riders to tailor the ignition timing to their specific engine build, fuel grade, and riding style. Additionally, the built-in adjustable rev limiter provides a critical safety net, protecting your valvetrain from over-revving during aggressive riding or missed shifts. These features make it the ideal choice for high-compression engines that are prone to detonation or “pinging.”

Single-Fire Technology for Smoother Operation

While many factory systems utilize “Dual-Fire” ignition (firing both cylinders simultaneously), the Dynatek system is capable of Single-Fire operation. By firing each cylinder independently on its own compression stroke, the system eliminates the “wasted spark” that occurs on the exhaust stroke. This technology significantly reduces engine vibration, lowers operating temperatures, and improves overall combustion efficiency, leading to a more refined riding experience.

Intelligent Starting Algorithm

V-Twin engines are notorious for “kick-back” during startup, which can cause expensive damage to starter clutches and primary drives. Dynatek’s intelligent starting technology manages the initial spark timing to ensure the engine is spinning freely before firing. This results in reliable, effortless starting even on large-displacement engines or in cold weather conditions, preserving the life of your battery and starter motor.

Fitment and Application Guide

This high-performance system is designed for “nose-cone” ignition setups on the following models:

Harley Big Twin (1970–1999): Fits Shovelhead and Evolution (Evo) models.
Harley Sportster (1971–2003): Fits Ironhead and 883/1200 Evolution Sportster models.
Custom Engines: Direct fit for S&S, RevTech, and Ultima engines using classic ignition configurations.

Dynatek High-Performance Ignition System For Harley
Dynatek High-Performance Ignition System uses magnetic rotors with OEM-style mechanical advance spark mechanisms to retain factory advance curves and eliminate points and condensers by replacing the points ignition with a high-performance dual fire system. Ignitions feature improved performance, easy installation. Completely self-contained, and install behind the points cover without modification.
Features:

Dual ignition fire method
Perfect ignition timing once and for all
Self-contained ignition system features Hall Effect magnetic sensors, which are not sensitive to rpm changes or affected by dirt and oil
Improves overall performance by changing the timing less than three degrees, extends plug life, eliminates the use of points and condensers; can be easily installed
Used and endorsed by many championship racers
1-year factory warranty
Made in USA

Note: The DS6-1 must be used with coils or combination of coils having 5 ohms resistance. Requires the addition of a mechanical advance unit on late model Harleys with OEM electronic ignitions.
