Put the bike on the kickstand then turn the air screw (the one to the left), out 2.5 turns.
Adjust your idle screw until the back wheel moves a little.
Go for a short ride to warm it up.
Now adjust that screw until the wheel either doesn't move or just moves a little. You're shooting for a nice little purr not choking, cutting out, etc.
You'll get the hang out of it.
I usually carry a tiny screwdriver for a little while after a big job on the bike just because it may need a little roadside adjustment on idle until I get it just right. that's just me though, some of these guys are a whole lot better tuning.
