W6 - Information
« on: 17 October, 2017, 20:48:27 »
Hello.
I do not have any experience with bikes, but have been searching for a Pre-war BSA for some time, as a long term project for my father and I.
A W6 is not too far away and I would like some assistance in understanding the model (any literature/manuals available?) & also regards sourcing parts. Its a 1936 year, but late 1935 build I believe.

Would I be correct in assuming the W6 is the side valve younger brother of the W33-7 or is it an empire star?  I believe the 6 was initially for side car use - but perfectly fine as a unit on it's own.  I read the side valve provided better torque for side car applications?  Other than that, are there many other differences?
In terms of sourcing parts, what is interchangeable - or does one have to specifically state that parts are required specifically for a 6?
 
I'd love to read up on the model too, but there isn't much on the 6 online, I'm still searching for any old books on them.
Any help/knowledge gratefully received.

Alternatively, if you'd recommend any other Pre-war BSA's that might be easier to source parts for, then I can direct my search there.

Best wishes.

The W6 similar to the 1933 W33-6 side valve.

You will not find a manual as we expect them to be today.

The W6 production was only about 1000 units, though the frame was shared with other models. Some were used by the Post Office and many were exported.

There are a number of general books worth considering, Pitmans Book of BSA 1935 edition (page below). The Book of BSA by D W Munro and of course the 1936 parts book (which covers the whole 1936 range)
