My 1938 BSA Y13 & BSA sports sidecar. Restored in 1989 and featured in Feb 1991 Classic Motorcycle. Still used in VMCC events.

Both 750cc BSAs, but so different! I had to do an internet search for the Y13; I knew nothing about it.

 I thought I'd let you know a bit more about my Y13. I bought it as an ex-sidecar racer restoration project with a car load of spares. It was fitted with high compression pistons & high lift cams. When I restored it in 1989 I kept the high comp pistons but fitted standard cams. I rode it solo for 18 months until I found the right BSA Sidecar which cost more than the bike. I ran it on a 22 tooth engine sprocket, solo gearing, but it was grossly under-geared so I fitted a 25 tooth sprocket. It was still under-geared so I fitted a 29 tooth engine sprocket, the biggest one that would fit inside the chaincase. It was still accelerating after it went of the end of the 85 mph speedo but became a bit wobbly. I put the 25 tooth sprocket bank on for my safety! With the sidecar I have run it on solo gearing for the last 30 years and it will cruise at 50 mph with my wife in the sidecar and will easily tackle the steepest hill  It handles like a dream and the exhaust note attracts lots of good attention.
