The crankcase vents into the airbox so at that mileage I'd expect a little blow-by the rings, hence the oil/fuel mist in the airbox.
Leaky carb boots would cause a hanging idle and other more persistent problems, so that's not likely to be the cause.
Fazerider's explanation is feasible, for sure.
Try without the air filter to see if there's an improvement. If you were able to knock dirt out, it might be more clogged up than your eyes lead you to believe.
Also, consider trimming 1cm off the end of each plug lead. They're screwed onto the plug caps and over time the end core gets brittle and the electrical connectivity is reduced.
