Sorry to hear that Dom.
Don't worry I'm sure it'll be great fun just pootling around at the back watching the race! I spoke to Rich today and he said he'd given up on squeezing more power from the 675 in order to focus on getting some billet stabilisers made up....
I'm actually sure you'll not only be out there getting the track sorted next Wednesday, but also beating all of us to the line on the day... Just don't bloody fall off!
