Sounds pretty normal to me, can't hear anything too awful put it that way. A few things I did to help mine at tick over and around and below 3k rpm were balance the carbs, check the tps, put some rubber from an old bicycle inner tube under each of the infill fairing screws to stop the bloody things buzzing and turned up the idle a tad to about 1250 or so as it was at about 1100. Has definitely improved it a bit, but its not a faultless burrrrrrr like a modern BMW S1000rr or something because its not a modern bike so I just accept that is how it is, it runs and rides fine. You can try and use some STP fuel cleaner before taking apart your carbs. I have also clipped my ht leads and got new spark plug caps, didnt really make a difference but worth doing for the price.
