One of the things I learned about BSAs is that they had a built in chain oiler. Inside the primary case is a small well that catches some of the primary chain oil. The oil passes through a tunnel to a rubber tube over the chain next to the sprocket. The result is a greasy bike. When I had mine apart I dropped some solder into the well, and removed the rubber hose. My BSAs stayed clean after that.
The chains of that era all had master links. So removing and installing a chain was easy. When I changed the motor oil, I boiled the chain in the used oil and hung it up on the clothes line with a coat hanger to allow the excess to drip off. Back then the used oil was poured down a sewer or a hole in the back yard. Wouldn't that make today's tree huggers scream.
