Spot on Rob, It's the same in the UK in classic racing.
Sam. 
Sam's dead right as usual. I have modern Keihins on the Bomber at present and have been hoping the Classic Racing club will let them in. Despite years of arguing against the old stuff on the gounds of rarity and cost (£1000 or $1750 is not an unusual cost for four) the CRMC will not budge and allow them in. It's madness really as the only difference in operation is the tickler changed to choke arrangement and once you're running and on track neither of those are in use.
Put that against the backdrop of Manx Norton replicas that have engines manufactured last week with modern materials and tolerances and they're legal why?
And I think there lies the problem with British classic racing - if your bike turns up with the wrong badge on the tank, i.e. Honda, you're an immediate outcast. I even got excluded from a parade with my Bomber because it had the number "7" on the numberboards as the scrutineer said the number had been retired by the FIM in honour of Barry Sheene. No-one sems to have told the club racers or for that matter Carlos Checa.....ah but then I did have the forbidden word "HONDA" written on the fairing and tank too...
Hypocrisy rules it seems...it's like living in the 50's when Soichiro came over to the TT all over again with the bigottry in certain of these clubs. Some people seem to carry things on too far and too long
