AJS & Matchless Owners Club

Could anyone advise where I might get hold of a set of hairpin valve Springs for a 1957 500CS?

Hi
The club spares does ones for 1958/59 500 cs models only part number is 024219/20 but i don't think there right for your model.
Looking at the part listing for your 1957 bike it lists 023363 and 023364 as the ones needed but club spare doesn't list those I'm afraid.

do you have worn ones , or none at all
if you have some can you measure free length (height) number of coils and wire thickness , take picture if you have them
