Dynatek Dyna S Dual Fire Ignition Kit For Harley 1970-1999
Dynatek Dyna S Dual Fire Ignition: Proven Performance for Classic Harleys
The Dynatek Dyna S Dual Fire Ignition Kit is a time-tested performance solution for Harley-Davidson enthusiasts looking to modernize their vintage V-Twin electrical system. Designed for models from 1970 through 1999, the Dyna S is a high-performance, solid-state ignition that fits entirely within the cam cover. By replacing mechanical points or failing factory electronic ignitions with a precise magnetic-pulse system, the Dyna S ensures your Shovelhead or Evolution engine runs smoother and starts faster.
Self-Contained Magnetic Pulse Technology
The beauty of the Dyna S lies in its simplicity. Unlike modern digital ignitions that require complex programming, the Dyna S uses a specialized magnetic pickup and rotor system. There are no moving parts to wear out, meaning you will never have to deal with pitted points or wandering timing again. This maintenance-free design provides consistent, high-energy spark delivery regardless of engine temperature or RPM, making it a favorite for both daily riders and custom builders.
Improved Starting and Idle Quality
Classic Harleys can be temperamental during startup. The Dynatek Dyna S addresses this by providing a stronger spark at lower voltages, which is critical during the heavy draw of a starter motor. Riders will immediately notice a crisper throttle response and a significantly more stable idle. By providing a more complete combustion cycle, the Dyna S helps eliminate the “coughs” and “stumbles” often associated with aged ignition systems.
Direct Dual-Fire Compatibility
This kit is a Dual-Fire system, meaning it is designed to work seamlessly with your motorcycle’s existing dual-fire coil. It utilizes the “wasted spark” method, firing both cylinders simultaneously, which simplifies the installation process. The Dyna S is engineered to work best with 5-ohm coils (standard for street use) or 3-ohm coils for racing applications, offering the flexibility to match your specific riding style.
Rugged Construction & Easy Installation
Built to survive the intense heat and vibration of a V-Twin engine, the Dyna S features a heavy-duty aluminum base plate and high-quality electronic components. Installation is straightforward: the module bolts directly into the factory ignition location in the nose cone. Because the entire system is contained behind the timing cover, you maintain the clean, classic look of your motorcycle without the need for unsightly external ignition boxes or additional wiring harnesses.
Fitment and Compatibility (1970–1999)
The Dynatek Dyna S (Part # DS6-1) is compatible with:
- Harley Big Twin (1970–1999): Shovelhead and Evolution (Evo) engines (uses the mechanical advance mechanism).
- Harley Sportster (1971–2003): Ironhead and Evolution Sportster models.
- Custom Engines: Ideal for S&S and other aftermarket V-Twins based on the classic nose-cone design.
