Title: Head gasket
Post by: shifter on May 21, 2024, 07:10:48 PM

Can someone  enlighten me if you have to anneal a copper head gasket  before refitting on a S90,   I have done previously  on a BSA 650 A10, not sure these days...

Pure copper gasket, yes. Annealing it softens it so seals better when head bolted down.

Yes Bryan there is a  very thin copper gasket not like the old brit bikes , it's so thin I'm wondering if it's soft enough not to anneal

Yes Bryan thoughts are the same as its  thin as tin foil, having  to wait for a replacement from the states as DS supplied one damaged from same place, will have sleep on it eh ...thanks for your input ..
