Tape faffing around is one thing - the ridiculous need to keep topping up the tank after each one is quite another.
As far as I am concerned, once the bikes are at the tapes for the first attempt, no-one should allowed to fiddle around with the bikes again until the race has finished, unless of course there was a crash.
No refuelling / no clutch adjusting / no chain adjusting / etc..
JUST GET ON WITH IT!!
