you should know my views on this by now. the powers that be should get their heads together and agree on one class, the 600 class, surely the most popular class in racing. the rule should be if it's a 600cc then it's legal. forget the regal, proddy or tuned or whatever, if it's a 600 then it's legal. time marches on, unfortunately the mcui doesn't. time for getting rid of the old wood and bring in some new blood that are up with the times.
ade!
