More power than stock systems, aggressive ignition curves and dyno-proven power gains
Immediately fires the first cylinder on kickers and reduces “kickback” and strain on electric start systems
Electronically adjustable advance allows timing based on engine modifications, operating conditions and gasoline; also utilizes stock VOES unit when applicable
Sealed electronic protection circuits protect from over-temperature, short circuits, coil failure and wiring errors
Fully adjustable rev limiter adjusts from 4000 to 8000 rpm; tach output accurate even at rev limits
Timing LED for static timing and diagnostic information
Can be used with single- or dual-plug heads (use suppression or spiral-core wires)
Spiral-core wires are recommended for maximum performance (do not use solid copper spark plug wires; they may cause interference with ignition system and accessories)
Entire unit fits under the point cover on 80” Evolution, Shovelhead Big Twin and Sportster models
Systems utilize 84-99 80” Evolution OEM pick-up rotor; on pre-84 models you will need to purchase OEM #32402-83 pick-up rotor or Part #2101-0025
Coils must have at least a 2 ohm primary resistance
Ignition systems, coils and plug wires sold separately
Ignition rotor includes bolt and lock washer
Made in the U.S.A.
NOTE: Single-fire systems must use single-fire coils with at least 2 ohms of resistance.
NOTE: If tach is inoperative after installation of the HI-4, you may require a tach adapter. The HI-4 tach output is compatible with ground-sensing tachs (including most OEM and aftermarket tachs), but some tachs require a high-voltage trigger pulse. In this case, install Crane tach adapter DS-242304.
