Back in the 1950s, the Grey Flash never came close to the success that the factory expected for its new racer unlike its twin brother. Eventually, a too short career and one year of production left only 31 Grey Flash. Indeed the DOHC of the Manx was a greater competitive advantage, but Vincent enthusiasts will argue that the Flash was lighter and that its “semi-OHV” head could have potentially delivered greater power, should the Vincent factory have had the funding to do so. This is precisely what Godet tries to demonstrate with his new Godet 500 Racer and to mention that this bike was a 30 years dream: make a Grey Flash competitive enough to beat a Manx!

Patrick already exceeded the Power and Torque of his benchmarked Manx and he recognizes that with more work he expects to get there.  So there is no secret; to beat a Manx, the Grey Flash needed at least a decent big port cylinder head and also a bigger bore to keep up with the modern Molnar Manx either in 90 or 95 mm bore configurations. So the challenge is now on the track, make this Godet 500 Racer enough so it will open opportunity to small production for other pilots which want to race Vincent at the top level of the Classic racing.

The quite massive silencer is imposed by the IHRO, we would sure prefer a classic “megaphone”.

The 92 mm bore X 75.2mm stroke is a competitive architecture against the latest Manx, but it needs more development. It has Hollow valves and a modern oil pump. © Patrick Godet
