MECHANICAL ADVANCE ELECTRONIC IGNITION FOR BIG TWIN & SPORTSTER

Weight: 1.73

• Designed for dual fire applications with single or dual spark plug heads
• Designed with built-in mechanical spark advance unit. Using Mallory's time tested breakerless ignition circuit, combined with modern surface mount Thermal-Clad^® construction, the kit can drive any ignition coil or combination of ignition coils with a total primary resistance of at least 2.0 OHMs
• We recommend ignition coils with 2.3-3.0 OHMs for racing applications and ignition coils with 3.0-4.0 OHMs for street and highway use
• Incorporates an infrared light beam and an optical interrupter to trigger the ignition. This type of trigger is extremely accurate and much more effective than hall effect (magnetic) type ignitions
• Use with spiral core or carbon core suppression type spark plug wires
• Billet alluminum ignition can easily be installed without removing the front cylinder head
• Installation insructions are included
