Hi Everyone,
I have just joined the forum having found it when looking for the answers to the opening topic on this thread,
I have owned and worked on BSA's for a long time, As a teen I always wanted an A10, not just any old one mind you it had to look "just right"
It never happened in my teens though and I was 32 before I got a 1961 Super Rocket rolling chassis and various bits in a box!!!.
I slowly gathered the right bits for it as I found or could afford them, working on other peoples bikes always seemed to take priority and besides I have several other bikes to get around on.
I finished the SR in 2002 and have covered over 8k miles on it.
Anyway Back to the RGS issues, recently I was offered a 1963 RGS with a verifying letter from the Gold Star Club, this along with the fact that the (now) previous owner had it for more than 20 years, back then they were not so sought after or "faked", leads me to believe its the real deal
Going through all the features mentioned here and comparing them to my SR, I still have a couple of unanswered questions ,
I had never heard that the RGS cylinder block had or was the only model to have the staggered fins? my SR has the same type !!
My Super Rocket does not have a top pump mount? no sign of it when the frame was blasted!!
I have been told that the later "Big valve" heads have a different part number
see,
http://atlanticgreen.com/a10alloyhead.htmAlso on the tuned RGS heads the last two numbers are ground out and stamped over
67-1549 now reads 67-1571. I have one of these with 1 3/16 inlet (30mm) it doesnt look to have been done afterwards by somebody
The frame drawing shown in a recent thread for a single cyl frame shows the gap between the frame member and the brackets, ?????
The manner and style of the way the frame number is stamped on RGS frames is very definite
I have been informed that there was a special jig to do this in the factory
I will post some photos when I figure out how
Regards
