About five minutes into the video, I said to myself “Jim’s got Covid “. I start rambling easily because my mind is all hazy. I sound just like you. I say this as, I’ve been down with COVID also.

Thank you. Very nice bike. I was an AA mechanic and worked on lot of these. Great video.

Helpfully, on a low power BMW airhead, the variable magnetism eliminates unnecessary alternator drag instead of, as on a permanent magnet system, having to dump surplus current as heat.

Last week I was talking to a 90 year old chap who has one of these and he’s done 150 thousand miles on it. He was moaning he hadn’t done his usual 10-15 miles a year.

My R100GS made me bald trying to learn the charging system coming from only knowledge of Japanese bikes. Then it made me swear off BMW's forever when the transmission chewed a bearing and left me stranded 50 miles down a 4x4-only track, which was 400 miles from home and out of cell service. That was one expensive motorcycle ownership experience.

It's not a generator, it's an alternator, it makes AC ,generators make DC

I agree, but the naming convention for motorcycles is a bit wonky! Technically dynamos make DC. Basically a mechanically driven DC motor. The rectification is done by the commutator and they output DC directly. Alternators make AC, but just for added confusion alternators generally output DC as the rectification is done internally. Generator is a "catch all" term we use in this industry.
