Cannonball Electric Starter Systems

The Cannonball StealthStarter system converts your classic kickstart-only motorcycle to electric start. After installation you just push the button or turn the key to fire up your classic Big Twin.

The Cannonball SSK electric start system bolts between kicker cover and transmission case. The stock kick starter can be retained. This intermediate housing, measuring just 19 mm, will be the only thing visible. Due to the system’s low width the overall appearance of your motorcycle will remain virtually unchanged. Primary drive, primary housing and oil tank will stay untouched.

Installation is fairly easy and straightforward. The kit includes everything needed for the conversion except for the battery, wires and starter button/switch which must be purchased separately. Depending on the configuration some other options are available separately.

Since the kicker cover and with it the clutch release lever move 19 mm to the right the following modifications may be necessary:

A longer clutch release lever may be necessary on some configurations. A longer lever is available separately.
A longer clutch pushrod will be necessary. Depending on the pushrod/throwout bearing used on your bike a special extended throwout bearing is available separately to fit your pushrod.

The stock 2-1 exhaust system will have to be routed slightly outward to compensate for the 19 mm offset of the kicker cover.

If the bike is still equipped with an early stock 6 V electrical system, you will have to convert this to 12 V.
A longer clutch pushrod (part of delivery) will be necessary. Depending on the pushrod/throwout bearing used on your bike a special extended throwout bearing is available separately to fit your pushrod.

Original rear fenders need to be dented. Alternatively, the included sheet metal “dent” can be welded to the fender.

In case your bike uses the older 47698-65 transmission mounting plate with the extension for the primary adjuster screw, the extension needs to be removed or our Cannonball SSK-S transmission mounting plate needs to be used.

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, starter relay 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. 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 stock clutch and primary chain drive.
