Essential mods for your Norton Commando

"Upgrade your alternator. Best to upgrade the Zener diode to modern regulator in the process."

FWIW, removing the OEM rectifier/Zener from my '73 and replacing it with a modern Podtronics system REDUCED charging voltage by .2 volts through the rev range. :rolleyes:

IOW, if the Podtronics had been OEM, a Lucas rectifier/zener would have been considered an upgrade. ;)

Totally agree re the Kegler clamps; I installed them back in '08 or thereabouts and they made a very noticeable improvement in handling.

You can make your own. (I did) or you can buy them from NYC norton already made and just install them. The clamps look like this installed.

No the NYC clamps don’t look like these as the clamps in your picture are Kegler clamps offered by Holland Norton Works (pair EUR 38,00) However I certainly agree it is the best option to secure the swing-arm spindle in the cradle tube.
Safe riding!

Sorry for stealing your picture off the internet. Sometimes a picture explains what something is better than writing 1000 words describing it. I get tired of writing long explanations that never seem to describe things clearly no matter how many times I edit them.... so I resort to posting a picture with the explanation for clarity. 😏

I never did modify my Combat cases. So far it has 40K miles and 50-some years on it. So not strictly needed. There are some differences of opinion on how it is done: Old Britts vs DynoDave method vs adding a small screen to the pickup.

The possible Combat oil starvation issue only arises at SIGNIFICANTLY SUSTAINED HIGH SPEEDS. So, correct, not "strictly" needed unless sustained high speeds are your anticipated mode of operation.
