After riding my BSA in attempt to diagnose the poor running issue the engine note change and it lost power significantly then stopped. I was then unable to feel any compression through the kick start, hence I pushed the bike home again.
On further investigation I discovered that the cylinder head gasket had a hole in it. I now suspect that the poor running of the engine was a sign of pending failure of the head gasket. At lower revs in 3rd and 4th gear while riding along there was not enough compression for the engine to function properly. Please see my earlier post titled "Losing power when in high gears" link = https://www.bsaownersclub.co.uk/bsaoc_forum/index.php?topic=3681.0 (https://www.bsaownersclub.co.uk/bsaoc_forum/index.php?topic=3681.0)
I've kept the old gasket as a template or reference for a new gasket that I can purchase.
Could you please help me? Where can buy a head gasket for a 1932 BSA W32-6, or where could I get one fabricated.

Hi there, I am no expert, but am surprised that your head gasket appears to be paper from your photo. Similar sv's e.g Ariel VB have a copper head gasket I believe. My 1938 "Book of the BSA" says to replace the gasket if suspect, but does not say what it is made of. If I am correct, you may need to cut one from some copper sheet if you can't find a source.
Cheers, Bevan
TT John, who posts on here gets solid copper head gaskets made. He may be able to advise.
Hi there,
I think the head gasket is the same as that of a G14. Lani from Copper Gaskets put some G14 copper head gaskets up on Ebay. I think he made batch but can also make one offs. I bought these and they are excellent. His website is: https://coppergaskets.us/
Kin regards,

Leon, thank you so much.
I've emailed Lani at Copper Gaskets Unlimited. If this turn out to be correct, your advice alone has made the membership fee worth while.
