Electronic ignition for your classic Honda! Plug and play, plugs into original wiring, mounts directly to original points plate mounts and replaces the points cam with the included signal rotor. Stronger, more consistent spark means better running and more reliable starting - this is a set-and-forget modification, once installed and timed, you never have to worry about ignition again - no more burnt out points, adjusting points gaps, cleaning, setting, replacing condensers. Just bolt it in, set the timing and enjoy riding!
