Electric start kit »Stealth Clutch Drive« by Cannonball; fits rigid frame 4-speed Big Twins Big Twins 1955-1957; 2.0 kW; The Netherlands; gross weight: 16.04 kg

The Cannonball Clutch Drive electric start kit for rigid frame Big Twins converts your classic kickstart-only motorcycle to electric start. After installation you just push the button or turn the key and your old Flathead, Knucklehead or Panhead will roar to life instantly. Another good thing with the CB starter kit is that it is almost invisible. The overall appearance of the motorcycle does not change at all and from 2 meters away you will have a hard time to spot anything. Primary housing, oil tank, rear fender - all can be retained, although a bit modified. The transmission with its stock kickstarter stays untouched. The kit includes everything needed for the conversion except for the battery, wires and starter button/switch, which must be purchased separately. If the bike is still equipped with the early stock 6V charging system you will have to convert this to 12 V, which means a suitable generator, regulator, coil and lamps need to be fitted. Detailed, step-by-step instructions guide through the installation, which is straightforward but which should be left to an experienced mechanic with fully equipped workshop.

The kits are intended for the use with primary chain drive.
