Racing at Wrangway Cross, near
Wellington.
Wellington.
I remember riding into what was quite a heavy drift, the snow very quickly compacting in front of me, and coming to a dead stop - with me nearly over the bars. This photo has notes. Move your mouse over the photo to see them.


So I followed the detailed instructions in an issue of Motorcycle Mechanics magazine and made it an "SS70". This involved getting a 70cc barrel from a breakers, and a brand new 70cc piston and ring. I took the piston into Mr Lush's school metalwork lesson, and machined the crown on a lathe to the specified dimensions so's it would fit the 50's combustion chamber. I remember firing it up for the first time, and the intake valve was just hitting the piston, so I had to file a little off the piston. But after that it went like a dream, in fact the power was so good that one day I totally lost drive. On investigation I found I'd sheared the square splines clean off the clutch basket!
I recall the speedo reading 64 (or 67?) mph at one point, prone with a tailwind heading downhill towards Minehead Fire Station. Not bad! This photo has notes. Move your mouse over the photo to see them.
