[QUOTE]\nAm assembling a checklist of problems CX500s of that kind of age are\nprone to. So far I've got rear swing arm internal rusting and battery\ncharger. Any more suggestions?[/QUOTE]\n\nAll of the above (depending on how you read usenet, I suppose...) is good\nadvice. And, heres my bit.\n\nAir Filter.\n\nI`ve never owned a bike that was so fussy about it, and they clog up quite\neasily so I believe. My own CX went from 35MPG around town to over 50MPG,\nand ran so much better, just by poking a few holes in the old filter with a\nscrewdriver. Take it out completely and it`ll run like a bag o shite. I`ve\ngot a new filter in there now mind you, and everything is happy.\n\nApart from that, jobs a goodun.
