Hi All, just over a week ago we were racing at Mallory with the VMCC. Ian put a camera on the 500 and these three short films go together to show one race - the first lap is rather sedate, as it is the sighting lap before the start. Enjoy it - I think he did! Cheers, Paul.

Dang that's exhilarating! That sounds superb. That's your shortened stroke squish banded 500 motor is it? What a beast.

Not short stroked - I have kept to the 84x90 mm dimensions of the 500 Bullet, but with a permissible over bore of 0.060", crank and piston to our spec, four main bearings and high ratio rockers and valves from the U.S. 8000rpm + can be reached. The 350 also uses the standard 70x90 dimensions, with maximum overbore as above, but with a short conrod and crank to our spec and can go to close to 9000 rpm. A short stroke 350 engine is nearing completion at present. They all have squish heads! Cheers, Paul.
