Thanks for the photo Dik. I have done a bit of research and suspect that the picture was taken on 20th April 1981 at Snetterton in race eight, the Centurion production race where Ray’s race number was 2. Some famous British racers in the starting line up. Kenny Irons, Greg Page, Phil Mellor, Howard Lees and even Damon Hill before he progressed to the world of 4 wheels. I’ve not found out the results yet, work in progress. There was another 501cc – 1300cc supporting race that day also, event ten, with Ray entered as bike No2. Photo could just as easily be from this race.

It is this history of these great bikes that makes them so interesting to own.
