Keith Duckworth

Because if they were going to beat the world, they'd have to know what the world was.

So, uh, Keith Duckworth of Cosworth fame said that when you adopt four valves, everything becomes better by the square root of two, which is roughly 1.41. And the MV500s had as little as 300 revs between the RPM of peak power and the RPM of valve float, which means that the rider had to give attention to engine management that should have been going to racing.

This was a very Italian trait for a long time.

It was, it was just how they did it.

Uh, they were using oil coolers, and I remember seeing him at the Canadian Grand Prix in 1967 take the fairing off and, off of the, uh, 250, the six-cylinder, and the two oil coolers are just there on either side of the engine hanging down by their oil lines, and the fairings had little slots that they clicked into.

So with oil cooling, it meant that they could take heat out of the head another way.

So, uh, what was going on here was that Irimajiri was following the same chain of evidence that Keith Duckworth was at Cosworth.

Let's make the surface area of the chamber smaller.
