Compu-Fire

Compu-Fire produces a range of performance-enhancing electrical components for Harley-Davidson models, focusing on ignition systems and starter motors.Their popular EZ fire starters features a Permanent Magnet Gear Reduction (PMGR) system that delivers up to 2kW of cranking energy, providing enhanced efficiency for older Harley models.

Their Single-Fire Ignition System is one of the most popular options, designed to improve engine performance by firing each cylinder independently. This system is compatible with many Harley models from the 1970s through the early 2000s, including Big Twin and Sportster models, but it is not suitable for fuel-injected bikes.
