About This Product

Bikers, listen up! If you need a new ignition module for your carbureted Harley, this 53-644 single fire electronic ignition is a solid choice. It’s made to OE standards and directly replaces the original part. It fits a bunch of models, including 1970-1999 Big Twin carbureted bikes, 1971-2003 Sportsters (except the 1200S Sport), and works with S&S, Ultima, RevTech, Shovelhead, and Evolution-based motors. Just a heads-up – it’s NOT for fuel-injected (EFI) models. It’s designed for high reliability and stable performance, so you can get back on the road with confidence. Always double-check your bike’s year, make, and model before buying to ensure compatibility. If you have any questions, just ask!
