About the Burt Munro pic.....wow....memories. I was at Burts pit one day, and he was showing me around his bike. He showed me the little rectangular hole (seen in the hinged panel over the engine) and told me he had a little knob on a rocker arm that he could feel against his belly...to use as a tach.
To tell the truth...I STILL don't know if he was pulling my leg! He certainly did (joshed me good) about some other stuff, and left me wondering for over 40 years.
I'd say my biggest regret in life, is that I never did figure out how to build a time machine. Pictures like this one leave a fella' wishing, don't they?
Thanks, JimL
