Sometimes bicycle fitters will do motorcycle fitting as well. It's worth your while to ask around your area.
The brake lever perch/master cylinder assembly on the R3 will turn on the bar, there's no built-in locating pin. So the first, simplest thing to try is changing the angle of the lever - when you do that, be 100% sure that none of the cables or hoses are pinched or hanging up when you turn the bars from lock to lock. It's best to have your brake and clutch levers at the same angle to avoid shoulder problems.
If that doesn't help, the stock handlebars will not rotate on the fork legs - you'd have to go to aftermarket clip-ons for that.
Since everything is connected, checking your lower body ergonomics can affect your upper body positioning too. Try to keep your pelvis rotated on the saddle so that your spine is neutral (with its natural lumbar curve, neither hunched over nor excessively swaybacked). Rearsets can sometimes help with that if your legs are long. A different saddle might help, too, if you find the stock saddle is locking you into an uncomfortable position. The R3's stock saddle is the grabbiest thing I've ever ridden on (except for maybe the one time I took a friend's Road King for a quarter mile or so) - for me, it's super comfortable for cruising, but hard to move around or change positions on.
