When we got the 'Electric Start' 850...it only really managed to crack up that Empire State Building type stroke when the motor was warm, first start of the day always involved the kick start, assisted by the 'button'...
Since we're in reminiscence mode...... I had the head on mine ported, fitted a 3S cam and 10.25:1 Omega pistons. I'm not sure that it actually made any difference to the performance and the porous head casting certainly didn't help. However, the high compression pistons ensured that I had to jump up and down on the kickstart and use the button every time.
This would be '77......
