I'm researching a bike, a ZB32 Gold Star. The bike is said to be correct 'matching numbers'. does this mean the frame and engine number should be identical or that the numbers on the frame and engine can be different as long as they 'match' the log book?

If the engine and frame numbers are the same I wouldn't go near it. It will have been re stamped (stolen?)
If the engine and frame numbers match the log book, all is rosy. If not as long as the frame number matches it is easy to change the engine number
If the engine and frame number match what came from the factory, this is the best.
Remember a Gold star is a primarily a racing bike so many engines got blown up and replaced

The Gold Star Owners Club in the UK should be able to answer your question on the numbers. They are easy to find online.

As a fan of the ZB GS machines I am curious if the bike in question has an engine in the 6000 series of numbers or is it an earlier engine with a lower number. The 6000 series, the last of the ZB32GS engines, would have a separate rockerbox type head and are the forerunners of the BB32GS.

Engines should not match frames..but may not have been di[atched together,, UK GSOC can usually confirm.


No generalisation is wholly true, not even this one.

Gordo, it has an engine number earlier than the 6000 series you mention

Gordo, as you're a fan of these bikes, would you happen to know where I can source the instruction manual for it? I've founds loads of online pdf versions of the BSA literature but all for much later models. What I'm really after are the instructions for my specific bike 1951 ZB32 on how to correctly change the oils and other basic servicing stuff.

I do not know if those early bikes came with the little hand books that came with the later models, they most likely had something. The BMS 'The GOLD STAR Book" by Bruce Main-Smith Publication has a maintenance section and complete parts pages for early and late models. The book was available from Prew in the UK and I would encourage you to get one.

While most of the info in the BMS book will apply to the ZB bikes there are a few things not covered for the pre-swing arm setups.

What you need are the early factory Service Sheets that covered individual topics like plunger suspension and early gearbox. These can usually be found free online but I do not have the links handy.

If you pm me with what you need I will see if I have them to can scan for you.

PS I just typed in BSA Service Sheets and found multiple sources for the data.

They did. I have the following 72-page 4"×6½ 'Instruction manuals' that would have come with ZB models:

Mc 193-10 July 1950
Mc 261-20 February 1951
Mc 261-20 May 1952 (yes, same number as the previous one)

as well as the following 78-page version that must have been available separately:

M.C.618—7½.5 Reprinted July 1961 covering 1946–1955

Burga007,

Might I recommend a couple of useful volumes:

BSA Motor Cycles (single cylinder) D W Munro (Pearson Publishing) Covers '45 -'59, including a lot on the early Gold Stars (cams, exhausts etc etc)

Henk Joor in Holland used to sell a CD with all the spare parts manuals for earlier BSAs. I have the one for the '51-'52 models, which includes the GS. Not exploded diagrams but illustrations of all parts and numbers. Might be worthwhile checking his website and emailing him.

Also, Kim the CD Man (listed at the top of this page under DCD/CD) sells a very comprehensive DVD of a huge range of manuals and parts lists for BSAs. Content is listed.

All BSA's came with an owners handbook from 1910 on ( nothing available for the Minerva engined BSA )
In fact the deluxe ones came wih a hardcover diary with space for payment stamps and sll sorts of things like UK road gradients UK light up times etc etc
These were compiled into a single volume titled "The Book of the BSA" along with brief model descriptions.
Post WWII then became type specific "The book of the BSA Singles", " the book of the BSA Twins" etc .

ZB's would be covered in Volume 12 or in the singles book credited to Mr Munroe
The BSA OC NZ have the 46-55 B series handbook as a pdf download MC 618 previously mentioned by Magneto Man
