No need to appoligise Glyn, the idea behind DD was Sunday racing so as not to disrupt those in the motorcycle trade that have business's to run on Saturdays
Trouble is circuits like Castle Combe, Oulton and Thruxton run more Noisey race days on Saturdays than they do Sundays and where two day meets are concerned the club racing likes to run the same timetable both days.
I can't see things changing with the circuits and neither do I see it changing with the Clubs (no matter what some people may think) which means the only option is for DD to adapt and this will effect some of those taking part.

Have fun changing those frames

Its worse than that.........Strengthening them

Thats where all that Airforce training pays off
