    I think the 1st thing to do is confirm exactly which carb you've got, have a look at the chart on page 19/20 in this pdf http://www.mikuni.com/pdf/vmmanual.pdf this should confirm what you've got, a 32mm VM roundslide is probably too small for a 500.


    If it were me, I'd do something about the too-loud exhaust before any carb alterations otherwise you'll end up doing them all again after either you or the local Plod get completely fed up with the racket, consider wrapping the baffle (if it's got one) or if you can't find a decent std silencer maybe a Motad or something from Brituro (BES 104R)?

    Come back to the forum once you've 100% identified the carb (and quietened things down) and expect (if 32mm) to be buying something bigger,
    there's tons of info here and the old forum on tuning & brassware for 34, 36 & 38mm VM's.

    Perfect country for back-road hooligans , thankfully most of the tourists get no further west than Keswick, just the occasional university minibus towing a trailer load of canoes.

    What carb settings would you recommend please with no air box/K&N, free flowing exhaust?

    Not bothered about performance - just easy starting and smooth running

    Many thanks

    Ah! you updated while I was typing, next step is to post a list of....

    Slide cutaway size, main jet size, pilot jet, needle jet & jet needle, you'll need a magnifying glass or jeweller's loupe to read the very small letters/numbers, one more question, is the filter a genuine K&N or a generic Chinese copy? If it ain't a K&N, bin it, most of the generic cheapo filters don't fit on the carb inlet properly and can block air bleed drillings in the carb inlet.
