Santa Pod raceway 15/07/2001
15 July was the Run wot you Brung, sponsored by PM. I rode up to a friends the night before near Oxford and checked the top end, to find that it was running too lean and hot, and had to change piston as it was starting to melt the crown. The cases weren't in the best condition with the threads beginnning to pull, but we got it sorted. I spend most of the day trying to keep the clutch in check and running 17 seconds, but didn’t realise the cases were rubbing. Out with the hacksaw on the tarmac, and lopped off the brass pluger housing from my gold plated and engraved chaincase. Over to the start line and ran a 15.98 and won. Not bad for a home tuned cast iron barrel.

We returned in September with my sprint scoot, using the same motor. This time it was geared up with an MSC Motoplat ignition which the flywheel was machined down and running methanol. Having spent ages trying to get the clutch right, we got it off the line in decent fashion only for something to give near the top of the strip. It still managed a 14.9 though. Got back and stripped it down, it was running an AF 62 crank, which had twisted and wiped out the stator plate. An expensive weekend.

New motor:Under development The next motor is based around a TS. The stroke is 64mm with a 120mm Rotax rod. To achieve this the cases needed a considerable amount of welding and machining to ensure that the crank fitted but also retained stength as a very deep channel is needed in the cases for the conrod to have clearance. Additionally the cylinder needs to be 11mm longer than standard, using a Wiseco Suzuki TS250 piston. Read more here...
