| I think you will find Paul Payne (Paynep) is running near enough the spec you mention, his bike certainlt seemed quicker at Castle Combe with the individual smoothbores now in place on short Mallossi manifolds. It has been set up by Moto Rapido so it should be one of the best BB bikes out there. But is still seriously compromised by the 400SS cylinder heads that are fitted to the 600s and are very restrictive on flow with there undersized valves etc.
Tony Brancatto says there is a lot he can do with my 583 engine and get a lot more power from it, sadly most of the mods are outside the rules,
I know Paul would like to try his 750SS heads on his 674. It would be interesting to see the results. |
