Jan asked in a follow up email what kind of bikes people were riding. My reply:

Hi Jan,

I ride a fuel injected bike in Clubsport. I would support 'with' and 'without' subclasses, but I don't think it should be automatically 'no fuel injection', as the bikes would never get newer and it would be just the same as Retro and PCRA. The big attraction of Clubsport is that each year different bikes become more competitive as later models become eligible.

Cheers,
Nick
