Hi everybody!

I have got a very bad print/copy of the BSA factory service sheet about "Internal Gearbox Ratios". A very interesting piece of information, but unfortunately it is absolutely impossible to read anything on my copy.

So perhaps anyone here might have a better version and could make a scan of it and send it to me?
Would be highly appreciated.

Cheers, Markus

P.S: I think this is Factory Service Sheet number 302B, consisting of 2 pages, see the pic attached, this is what page 1 looks like.

Hi All,
Gate crashing a thread here but does anyone have the charts for the gearboxes  used on the plunger singles?
I have just completed sorting out a B32 that is in trials trim for a friend and rode it about 50 miles today
the first and second ratios are low and then theres a massive jump to third and top,
I know this sounds like a typical trials setup but its a pain on the road which is where the bike will be used
Regards

Some of this might be usefull. Although this is out of the parts book for the 1949 to 1953 models there are some bits that are for the early swingarm box.

I will keep looking as I might have some other stuff, too many parts books !
