Title: BSA A7 engine numbers
Post by: stompy on March 05, 2018, 09:30:38 AM

Hello,I have BSA A7 cases that start with FA7 followed by 5 numbers. From what I can find,no A7 motors started with an F... (some frames did). The numbers don't look tampered with. Any ideas? Thanks.

I've checked two lists & definitely no effs.

As has been said no engine numbers began with FA7 only frames. A possible explanation could be if there is no sign of tampering is that the cases were replacement ones supplied by the factory  if so these were not stamped by BSA but were supposed to be stamped up by the dealer but I have heard of cases that were not stamped by the dealer so you have 2 explanations 1 they were stamped by a dealer but were mistakenly stamped with a frame number or 2 a previous owner has done the same thing. The correct size  stamps are not hard to obtain.
