New engine for Rossi

by dean adams
Wednesday, August 22, 2007
Yamaha has now joined Suzuki and Kawasaki with a pneumatic valve-equipped MotoGP engine. Valentino Rossi tested a new engine at the Brno test this week and knowledgeable sources say that the new Yamaha M1 mill has pneumatic valves.

The new-style engine is delivers another 1000 rpm on top end and offers better acceleration than the "conventional" Yamaha MotoGP engine.

While a step in the right direction, clearly pneumatic valves weren't an immediate fix for what ails the Yamaha MotoGP team. Rossi and the air-valve motor actually lapped slower than Colin Edwards and the conventional Yamaha MotoGP engine at the Brno test.

it's probably how that power is delivered compared to the old valvespring motor, it would only need to tweak the engine mapping to get the power delivery spot on OR they have gone the screamer route this time.
