I've found that both the old stuff and the new stuff works pretty well. |
On my M21, all the electrics (magneto, dynamo, and regulator) are the old originals and still do the job. On my A10, they're some original (magneto, dynamo), but the old mechanical regulator failed and I replaced it with an electronic one, which also works well.
On my A65, it has the original alternator, with a Tympanium regulator/rectifier, and a Boyer ignition. I like an EI on a twin instead of points/coils because with the BSA (and probably Triumph and Norton ignitions) you can never (by design) get the point gap, timing, and dwell correct at one time ... something has to be compromised to make it work. With an EI, the trigger plate geometry assures that the two cylinders are in sync with each other, and it makes for a smoother ride.
On my Norton, it was running great with the stock electrics, but I replaced the points with an EI for the above reasons. I still have the stock alternator, starter, rectifier, and Zener diodes. Matter of fact, the rectifier failed after 45 years, and I replaced it with the 51 year old rectifier off my A65 that I took off of it, and it works fine ...
