A friend of mine has an old 64, 65, or 66 BSA A65 in a shed in his backyard that has not run in years and he will not part with. Anyway, I was looking at it the last time I was over there and saw that the numbers on the engine started with A65T and the numbers on the frame started with A50. Could someone tell me if the bike originally came with the engine and frame numbers like this or is it have a non-matching numbers motorcycle?
Somewhere I read, on here or some other BSA site, the exact number that change was made. Found it on the BSA owners site:
UNIT A-SERIES 1966 'A' series machines started the season with A50, A50B and A50C frame designations with the usual non-matching engine markings. After frame 3200 the engine and frame markings were the same. There was a short period where the engine marking matched the frame marking but the frame prefix was A50
