I am looking for a service manual to give me some guidance re servicing/ maintaining my 1945 B31. The Haynes manual range don't appear to cover the early B31.Is this correct, or am I missing something ?

I've maybe seen something on eBay. But, if you might keep the bike or any other BSA, best investment you could make is the BSA CD set offered for sale through this site. Probably the best motorcycle tool I have bought.

From what I can see the 1954 to 1961 Haynes manual has almost all you need to know given how little the machines changed. For example all three frame types are covered and both the alloy and iron engines are shown.

For sure your gearbox is not covered but the M type shown is quite similar with the exception I think being the gear changing bits.

The basic B31 engine will be as per the iron top end engine shown with only small detail differences that will be obvious.

There are service sheets that were published in those days but they are not always easy to come by. For them folks on this site will normally have that info if you are in need.

Without frequent roadside repairs there is no fun in riding!

Thanks Gordo
At the moment I am looking for some guidance re timing.The bike was running well,starting fine until the points cover rattled loose.I'm not sure what has happened, but suspect the points may have slipped.I am looking for some instruction (with diagram/picture if possible) re checking / setting the timing.

I am sure this will be the start of many things I will need to get to the bottom of, so thanks for the headsup.

Cheers

Graham
