I'm with you Butch, there was a gentlemans agreement to keep things as even as possible and leave the 620 on standard bore.
The 583's were a little bit slower, but nothing too significant. I was just about able to reel in Andy (Team CK&AK) down the straight, but not by much, and Phil (583 big bored) was losing a few meters on me down there too but was able to keep on my tail for the whole of both races because he seemed to be the better rider.
I think the 620 bb's would be bad for the series, but at the end of it all we'll know who the trophies SHOULD have been going to, so if someone want to throw a shed load of money into boring a 620 then let them, but their victories will be hollow.
