Dynatek DS6-2 Dyna S Points Replacement - Carb Models 70-88

Dynatek Dyna S Ignition System (DS6-2) is a high-performance, self-contained electronic ignition designed to replace traditional points systems on Harley-Davidson motorcycles. Featuring single-fire technology, this system fires each cylinder independently—delivering more precise ignition timing, improved combustion efficiency, and noticeably smoother engine operation.

Unlike factory dual-fire systems that fire both cylinders simultaneously, the DS6-2 eliminates wasted spark, reducing vibration, backfiring, and power loss while improving throttle response and starting performance.

Key Features: Complete points replacement electronic ignition system Single-fire operation for precise cylinder timing and improved performance Reduces vibration, backfiring, and intake reversion Improves throttle response, starting, and overall rideability Self-contained design mounts behind ignition cover Retains factory mechanical advance system Proven performance gains, especially on modified engines Fitment: Harley-Davidson carbureted models – 1970–2003 Suits: Big Twin models (Shovelhead & Evolution) Sportster models (ironhead & EVO) Important Notes: Requires 5-ohm primary resistance coils for street use Not recommended for use with OEM coils Requires mechanical advance unit on some later models Not compatible with fuel-injected models
