My bike is running halfway decently now that I've fixed the stiff diaphragm problem that was causing the cylinders to run differently.
But ... I noticed that the carb slides have restrictors installed in the holes on their bottoms. Which means that someone likely attempted a Dynojet install at some time in the past. As for the carb needles, they appear to have multiple positions for the circlip instead of a single one. Does that indicate that they're non-stock (Dynojet or otherwise)? Or did some GS500s come with multi-position needles as stock?
Jetting is 145/40, plugs are slightly sooty but not indicative of running very rich (not _covered_ with soot). If I have the Dynojet needles, should I attempt to return to stock and remove the slide restrictors?
Thanks,

It indicates that they're not US stock needles. While they could be UK/Euro spec, since you have the plugs in the slides, I think DynoJet is a safe bet.
So, yeah, you're undoubtedly running rich at the top end at least. Some people have gotten the DJ kit to work and say they're satisfied, but a lot of folks have had problems. If it were me, I'd change it, if only so that I'd have comparable data from lots of others to work with.
