You can tell a little by listening, but not a whole lot. Its never the same listening on a recording as to listening to a real bike. Essentially the burble burble burble is excess fuel firing every second stroke instead of every stroke. The reality is you need some excess fuel at light throttle applications to make sure there is enough for when you're under heavy load. My suggestion is to have a play and see how it effects the bike. Turn the air screw out another turn and ride and see if you feel a difference. Turn it right in and see if the bike stalls. Its through experiencing the rich and the lean where you learn what feels just right.

..or you could just be happy with it as it is! Like I said.. very personal..

In the past I've spent a whole day jetting only to come back to where I originally started. LOL
