HI-4 Single Fire Performance Ignition.
A performance ignition for the serious race or street performance enthusiast that demands the best in function and reliability. This ignition allows fine tuning to match the ignition requirements for race or street use. The entire unit fits in the nose cone with no inconvenient external module. 

Adjustable advance curve, adjustable rev limiter and independent rear cylinder timing are included to maximize performance. The static timing LED provides easy installation with no guesswork. There is a kickstart/electric start mode that will eliminate kickback upon start up. (We recommend using coil Part Number 8-3001 or 8-3005.)

HI-1 Single Fire Performance Ignition. Mechanical
Single fire ignition systems require the use of a single fire ignition coil like the Crane Hi-Intensity single fire performance ignition coil, (Crane Cams Part Number 8-3001 or 8-3005.) The HI-2 requires the use of a mechanical advance assembly that is not included. 

Can be used with dual plug heads, in which case two dual fire ignition coils are used (Crane Cams Part Number 8-3002 or 8-3006). This system will require a tachometer adapter (Crane Cams Part Number 8-2050) if your bike has an electric tachometer.
