The Cannonball Kick Drive electric start kit for 4-speed, swingarm 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 Panhead will roar to life instantly.
With the CB Kick Drive electric start kit the transmission receives an intermediate housing between kicker cover and main case, where the starter system attaches. The stock kickstarter can be retained. This intermediate housing will be the only thing visible so the overall appearance of your motorcycle will barely change.
The primary drive, primary housing and oil tank stay untouched, only your stock 2-1 exhaust and the transmission base plates →1964 require small modifications. Since the system works with an unchanged primary drive, it also allows installation of custom belt drives, custom primary covers, running open primaries, etc.
Installation is fairly easy and straightforward. The kit includes everything needed for the conversion except for the battery, wires, starter button/switch and a special clutch throwout bearing, which must be purchased separately. This special throwout bearing acts as a spacer to compensate for the intermediate housing and works with your stock clutch pushrod. Big Twins 1958-1964 also require a longer clutch release lever which is available separately, too. 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, horn and lamps need to be fitted.
