Compu-Fire Electronic Ignition

These digital ignitions use advanced Hall-Cell triggering and surface mount technology with a convenient built-in ‘Accu-Ray’ static timing LED. They completely eliminate the rev-limiter and have built-in adapters to correct the tachometer output.
Fit non-EFI Evolution Big Twin models from 1970 thru 2000 and Sportster models from 1971 thru 2003.
