These guys have been successfully running this BSA on the Outlaw Circuit against some of the same bikes that make up the Twins Class at Tucson. They pre-registered for Tucson ,got their paperwork in the mail, loaded up the truck in Montana and headed for Arizona. When the AMA Tech Crew looked at the bike ,they said sorry we think you guys are about 40 years too late and would not let them run.
They recently out qualified a certain Green Kawasaki in Sturgis and were immediately protested over their loud megaphones. They quickly built some slightly baffled mufflers which easily past the soundcheck and low and behold, cured a slight flat spot they had been fighting and instantly improved their lap times.
Thank you ! famous Tuner.
