head gasket AJS 250 CSR

[triumph thaiger]

I need a new cylinder head gasket for my AJS 250 CSR .
What came out was a home made job made of thick gasket paper and a thin copper ring which sat over the top edge of the cylinder barrel . I believe a 2 part gasket ( copper or aluminium around the barrel and gasket parer for the vicinity of the push rod tunnels ) is best ? I live in Thailand and I'm afraid the country is not exactly awash with spare parts for AJS motorcycles. So I'd like to make the head gasket myself.
Can anyone advise what thickness copper or alu to use ? Many thanks in advance and cheers from sunny Phuket

Hi Maxim,

Here is a photo of a 250 head gasket:


According to my micrometer, the gasket material is 1.72mm thick and the copper ring is 2.20mm.

Good luck!
Paul.
