My first British bike. I purchased this NorBsa from a Arizona Motor-sports Hall of famer. 1966 Norton featherbed frame with a 1952 BSA B33 500cc. I have to do all of the electrical system. Looking for advice/help on what's best. 6V to 12V? Is there solid state replacement for certain components? Maybe just constant loss battery system? HELP...
Yes, I know it's not fast, but it does have a lot of character.

What do you have there is Lucas Magdyno ???
You can either rewound it for 12V output, or attach a 12V electronic regulator to get 12V output.
12v is always better with current half of the 6V system.
The resistive power loses in dynamo will be reduced 4x ( remembering that power loss is proportional to the square of the current ).

Right profile shot. Sounds like re-winding the "DynaMag" to 12V would be the way, more current and more efficient. Know anybody that can do it?

Another option, look out for late B31/33 alternator primary cases, police used these but they are not common. This site has some in the UK. The drive side crank end would need mods to take the rotor and you would lose the cush drive.

I'm now thinking about going constant loss battery system. High capacity 12v battery with low current LED lights. Has anybody installed the Pazon Ign. systems? She's not an easy starter. I'm not expecting to tour the U.S. with this, but I would like to ride it around on a Sunday and have a reliable starting bike.
Thanks everyone for the great compliments and advice!

Beautiful machine: Is that an alloy top end or silver paint?

Alloy. The engine sn# is 2B. 33. A.8666. A =Alloy (at least that's what I heard)
But, yes it is alloy.

P.S 2 months ago I was in B.C. Vancouver,Sunshine Coast. Loved it. Be great to ride there.

Sweet: I was pretty sure it was alloy given how the iron barrel fins are not the same. I have a 1950 ZB33A engine project.

What I like about the ZB33A engines is that historian/author Roy Bacon states in his BSA buyers guide; "For 1950 only there was an alloy engine option listed for the road B models, although it seems unlikely that any were ever supplied". However he lists them from 50-53 in the ratings listing as a four star machine.

So it's ZB33A. I haven't tracked down the exact date it was built yet. That's why I'm here. (aint the inter-tubes great) Roy Bacon. BSA buyers guide. Is this the Gold standard for BSA Info/opinion ? Responses from Scotland, Canada, North Carolina, and good old New York. Cool mix of locations...

No, Roy uses Factory parts lists and brochures which do not tell the full story, plus he ignores or forgets to cover market variations away from Home market.

Congrats on getting such a tasty bike.
