550 0502 HI 4N Ignition Kit Harley Davidson FL 1200 1970 1977 Black Grey

Features: More power than the stock ignition. Single-fire and dual-fire function built into a single module. All-metal housing provides improved heat dissipation. Ignition advance and timing degree markings are on the metal flange. Convenient cable notch in the housing makes installation easier and prevents damage to the cable. Sensor and magnet housings are built into the all-metal back plate to protect the sensors from damage during installation. Sensor housings contain advanced flux concentrators with high-temperature-resistant samarium/cobalt magnets for accurate, reliable ignition triggering. Electronics are fully enclosed to resist vibration, moisture and dirt. All electronics are mounted directly to the metal housing, which acts as a heat sink. Four rotary switches for ignition mode selection, advance rate, and rev limit. Switches provide accurate, repeatable settings. Includes ignition module, S&S ignition coil and correct-length spark plug wires. Made in the USA. Not for fuel-injected models.
