Aha - thanks for that Benelli, i'm surprised that's the first time they've inspected the top 3, thought it was mandatory for all the racing. I honestly can't see the point of spending all that time/money and more importantly gambling your physical self on something that in effect is a pointless exercise. The obvious cheating explains the lack of response from the teams involved and the cc's mentioned is the size of the big bore kits that were readily available when ZXR's were being sold new.
