Hi All, at last the BSA has arrived, even nicer as it is a wedding present , I'm stripping it to see what is required to get it running and I notice that the engine is leaning BACKWARDS in the frame, e.g. the cylinders are not vertical but have a definite backward slant, the frame appears to be straight and I have checked the top tube as instructed by the
manual and all is in order. My question, In it's life although there are many original parts on the bike , there have been bodgers at work, IF the motor has come out in the past, is it possible to re-install it incorrectly?

Johnny.
