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.
