Installing a Colorado Norton Works Electric Starter

| 2/13/2020 2:14:00 PM


BikeMaster logoBack in 2018 we installed an Alton electric starter on editor Hall’s Norton Commando. This time around we’re installing the other easily sourced electric starter kit, from Colorado Norton Works. As you can see from the photo above, this is a comprehensive kit that includes a belt drive conversion in addition to the starter. Like the Alton, this kit requires you to replace the inner chain case. The CNW starter requires you to remove the stock ham can air cleaner, as the starter motor takes up some of that space. Fortunately they also sell the K&N compact air cleaner that does fit with the starter. There’s rumor of a smaller stock looking air cleaner in the works from CNW. We’ll look at that when it comes out. Sometimes belt drives change the primary ratio, but this kit barely changes it, from 2.19 to 2.188. The included instructions are comprehensive, follow them and you’ll do fine. If your battery has a few years on it, replace it, preferably with an AGM battery, the largest that will fit in your battery space. We sourced a DEKA ETX16L from our local battery store.

1. Begin by disconnecting the battery. Find the two wires running from the alternator to the wiring harness and unhook them. Disconnect the wires running to the rear brake switch and remove the rear brake pedal. Remove the center bolt from the outer chain case and drain the primary case. Remove the primary cover.


2. Remove the clutch-adjusting nut and clutch rod.

I have an E-Start commando with good 4 brush higher ratio aftermarket motor. The idea of putting this beefier looking belt drive setup is intriguing.Money wise is it worth it? What might be gained? Will the new starter system fit under the '75's flat air cleaner type housing? If not, can my starter be used instead of the one that is with the kit?

Since the original Lucas alternator is used, you can use the standard timing gauge and rotor marks to time it.

Is there a method for ignition timing with a strobe light with this system installed?
