When I wrote '25 years on' this month I mentioned Graham Jamesons claim that he had modified the cam plate design slightly using the then state of the art equipment and this resulted in a better gearchange. I know from experience that the 5 speed surtees box is a much better change and of course those camplate tracks are completely different. Perhaps the years of 'fun' trying to race a twin and the shortcommings of the gearbox comes down to the lack of a few alterations to a cam plate . After years if frustration I sometimes think its a problem that no end of fiddling with springs eccentric bolts and ratchet teeth can overcome
