For the 1150 Adventure. I think it is the titanium can.....onto a Y piece. There is a 'hose clamp' type screw clamp that goes over the stub of the end can onto the Ypiece pipe to stop it blowing. Can anyone help me with the size I need please. Mine has disintegrated on disassembly, it was pretty well corroded through to be fair.... there is a Mikalor W5 which is 316 stainless for about £7, so worth the little extra I think, I just need to know which size to buy - and I can't work it out with a ruler in my dark 'hole'. I can't get any sense out of the Remus website.
