Description
 

Crane Cams Single Fire HI-4 Ignition Module
- single fire single or dual plug heads
- one of the most adjustable and user friendly high tech ignition systems available on the market today
- completely contained under the gear cover housing with no need for external OEM ignition module and RPM limiter
- switch for kickstart or electric start. the kickstart mode fires the first cylinder that comes up on compression stroke for that impressive one kick starting with little chance of kickback. the electric start mode allows the starter to spin over before the ignition is activated, that creates less draw on the battery and less strain on the starter motor
- fully adjustable advance curves and adjustable REV limiter from 4000/8000 RPM
- a tachometer hook up wire is standard on both units
- OEM point/race switch. OEM point mode can be used with or without the OEM VOES unit for street usage and the race mode is for all out full throttle racing
- units include an LED light for simple static timing and troubleshooting
- must be run with spiral core spark plug wires and ignition coils with at least 2 OHM primary resistance
- complete detailed instructions included
