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.
 
My mind is wandering again.

What I really would like ideas on is a good battery retention mechanism. Another poorly designed contraption that didn't last very long on my first Commando like the '71 sidestand. 😒
Simple and easily implemented is desired. I'll admit I'm lazy about that particular project.
The battery thing is ALWAYS a problem
 
If had a road-going Commando, I would keep it looking as near standard as possible, However I would fiddle the gearbox - it is the only thing which makes the standard motor slow. Gold Star BSAs have RRT2 gearboxes which makes the bike fast but useless under about 40MPH, due to the high racing first gear. A Commando gearbox with the top 3 gears as Manx Norton ratios, and the Commando first gear, would require a change in riding style, however it might be a lot more fun. The gears in most Norton gearboxes fit other Norton boxes. A Manx cluster cost me $730 Australian, and helped the bike to be much faster in every gear except first. I tried to race with a normal Commando gearbox - the bike was far too slow. The Manx cluster is perfect everywhere, except in first gear. To get the bike going in traffic would be horrendous. It would be like riding a DBD34 BSA but more dangerous.
 
Al a standard commando GB is all good for a road going bike as long as the layshaft bearing has been replaced, with the work done to my Norton it runs very freely and have been clocked over 120 mph, how fast do you want to go on the road, maybe in my younger days I use to ride flat out in top but these days taking it over the ton is good enough for me, I have nothing to prove and it gets over the ton pretty good.
As for first well that is just for taking off, second and third are the open it up gears and my bike will rev to the ton + in 3rd gear if I let it as my motor with the work done to it does rev very freely, its knowing how far you can rev it before it goes bang and like I say my hoon days are over and of course the fun police will catch you one day if you do keep hooning around.
Like I say the Commando GB will be ok if you look after it in 49+ years I am still running all my original gears, shafts, except for the first kickstart gear as where the KS pawl sat in the gear the slot had worn and the kicker use to slip and wore out the pawl and the pawl after replacing the pawl 4x so I replaced that and had to replace the kickstart shaft where it broke where the pawl connected, other than the layshaft bearing everything else is original and for the first 3 years of its life my Norton coped a hiding, burn outs every Friday/Saturday night, yes young and silly at 17 years old but never blew the box up till the layshaft bearing blew, but that blew when putting it into gear when I was about to leave my house.
Al you have stated many times you have never rode a road going Commando and you stop riding on the road at age 29 I think so really you are no expert on riding a road going Commando, but you seem to know all, not.
A well set up Commando can be a great street bike as well a good long distant traveler and the stock GB works quiet well, they shift very smoothly without any clunks like most newer bikes do and the stock gearing is quite good, but some do gear them up, but I like the stock gearing, suite me for my needs.
So Al stop judging a Commando till you have ridden one on the road, but of course we all know that will never happen when you don't ride on the road.
As well the right shift is the right way for a Norton to be, one up 3 down for that quick shift into the other gear.
Like you say Al, if I had a road going Commando, till then you are dreaming.

Ashley (49+ years riding my Norton on the road)
