The mag is no longer in use, I've opted for electronic ignition. This conversion was originally fitted to Nortons. I've also upgraded the dynamo to an alternator, fits in the same place as the dynamo so is in keeping with the vehicle. There have been many upgrades to this engine; if anybody was interested I would write them down.what is the cap thing on the end of the magneto?
Hello Simon,Triumph clutch?
Hello Simon,I had a couple of A10s, plunger and swingarm, and I was sure it was a 6 Spring unit fitted to them, and felt I recognised the Triumph basket.
Hello Graham,I hope that have uprated battery my 6 volt one would not run the headlight alone for a few minutes and the generator/dynamo was total crap
I’ve had 5 to date ever since they came out in April 99. My present one was first registered 1st April 99 and maybe the earliest still on the road.Hello Simon,
Here's the mainshaft of the swinging arm gearbox. As you can see it has a taper and a woodruff key.

This is the plunger mainshaft, totally different end.

No woodruff key as the clutch slides onto the splines.

I have no idea when BSA stopped using the six spring clutch. In my ignorance, I thought it was only used on the plunger as I know that shaft, above, was called a plunger mainshaft.
You own a Hayabusa Simon and you still have a licence? You must flap about on the handle bars when you open that up.
Hello Steve,fs1e took me back to being 16 I loved my fizzer
Hello Simon,I used to drag race and land speed race
Mine was 1974 so unrestricted and still had the pedals I fitted a 65cc big bore kit and a micron exhaust did 70mph cracking bike but my best was a tzr 250 with twin microns that bike sounded beautiful and went like stink how I love the sound of a 2 stroke engineHello Steve,
My brother had one of the first one's made, it was gold and it was called an SS50; truly amazing motorbike or should I say moped? So much so, for my son's 16th birthday I did a 1900 mile round trip to get him one. It was one of the later versions with the governed engine and the foot pedals removed but, with a bit of tinkering and a big bore kit, it went along at a respectable speed. Of course, he hated it because his friend had an Aprilia 50cc.
