It is in the regulations that proffesional support is not allowed. Although i'm sure for one race, if there was a car available you might get away with it.
There are several cars on the
www.750mc.co.uk classified page, there was also one i remember on ebay a couple of days ago. So that may be worth checking.
Nothing has changed in the last couple of years in the regs for the championship except belts and exstinguisher.
Hope we see you soon.
