Tour de France 2009

the bike will have to pass scrutineering and will have bore diameter, stroke, inlet and exhaust dimensions, wheelbase, weight etc all within set limits by the governing body.
the fuel will also be tested before and after the race.

100% Correct.

But use the analogy a well known BC mechanic told me after bejing, you don't run an F1 Ferrari on supermarket unleaded.

Going to bed, got training in the morning *
