In addition to the Lucas lighting, They had a Lucas voltage regulator. It was simply a Zener Diode that dumped everything above 6 volts direct to ground. It was set in a heat sink mounted to the forks, below the headlamp. Brit bike riders often had the lines of the fins on the heat sink branded into the palm of their hands. It was normal to wonder what it was and grab it, hence branded lines.

I didn't know that: thanks! :thumbup:

All of the sudden, this 1968 performance is starting to make some sense!

And who can forget "tickle carburetors" on the Triumph's & BSA's?

I remember them well. I raced a BSA 441 in the open enduro. Get it hot, kill it and you will be sitting for a while. I have owned several Triumphs in cluding a "Tiger Cub". Anyone remember those?
