Unfortunately neither bike finished but the 250 got a flying lap at 90.5 mph and the 350 a standing start lap at about 94 mph. The 350 exhaust cracked at Ramsey so it was off tune over the mountain so better lap times should be possible.
That's just brilliant stuff, thanks for the link John. The kiwis can just get it done eh? More excellent engineers per head of population than anywhere else surely. Inspires me on my own project, which is making good, if slow progress. A KSS motor with KTT mods/components, into an RS frame.
