What exhaust should my G12CSR have?

Post by Columbo John »

I'm fairly certain that my 1961 G12 CSR should have a siamese exhaust pipe with a parallel silencer. But...... looking on the Armours website, they only list the 'parallel silencer' pipes for a 1959 single down tube bike:

The only other one they list is for the CS models with the kicked up silencer. Or should I be going someone else for my exhaust?

Siamese pipes came as standard for CSR's, an optional extra was twin pipes and twin silencers. If you look at page 67 of your parts list you will see all the parts needed to convert CSR's and CS's to twin pipes and silencers.

It looks like the 1960 on Siamese one is stainless https://www.armoursltd.co.uk/product/si ... hless-csr/

Well spotted, I wonder why they do this pipe in stainless but not chrome? I shall give them a call. :beer:
