If anybody could give me any information on a 1946 BSA XB31 let me know please.
If anybody knows of anywere I can get a manual or engine diagram (exploded). And parts such as piston rings and push rods.
I think the engine is a 350, engine number; XB 31 2378 rigid frame.
Thanks

The actual model is a 350cc B31, the 'X' prefix is a production prefix for a particular period = 1945-47, later models being YB, ZB, BB, CB etc.

Hello; Your BSA XB-31 could be the earlier model made in the production year 1945. Does your bike have oil drain screws in the bottom of the front fork tubes.
Send me an email.
Thanks
