Yes old one I removed with a lever. The ones I have must be cheapos or the wrong ones. I guess I'll need some from DS.
I have had a bit of a hunt round amongst my spare parts and found what look like some sort of Asbestos replacement type gaskets bound with copper wire spiral binding.I can't get my calipers into the exhuast port to measure the diameter its about 38mm at its narrowest being tappered from about 40-41m.In the photo are two that are too big to fit they measure 39.7 mm for the enclosed copper gasket & 39.3mm for the open sandwich one with the blue filling.Looking on the internet there are also alloy ones available - like this one below.I suspect the two copper gaskets are for the 500.https://www.ebay.co.uk/itm/283814932934?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649The exhuast port has no paint on it so that's not causing the problem - I've given the port area a clean & removed what little paint that was - still too tight except of course the white soft gaskets..IMG_20220118_131444 by Macabe Thiele, on Flickr
