Hello,
I introduced myself already in 2013. I am from Germany and I have got BSA singles (B33, M20).
End of last year I bought a BSA A7 long stroke from 1950. I intend to bring it back on the road as soon as possible. The engine was partly disassembled. I decided to bring the engine to a known workshop for inspection. A worn big end shell was found and the pistons have a clearance of 0.16mm. The specialist mentioned that the big end shell of a A65 can suit and he was afraid that there are no pistons on the market.
Now, I would like to take care for the parts in advance. I’m looking for new pistons (+0.040) and big end shell. I would appreciate if somebody has a recommendation’s or comments.
Best regards
Johannes
