I don't know about your motor but my motor has had a "little" work done under da hood and it idles in my opinion a little better (stronger) than most to which I keep my idle right down there around a grand and even lower without issue.... Her cold idle is a fun one to listen to as she willingly lumps along in the 7 to 8 hundred RPM range.
But most Concours motors and Owners are better off set up higher as I commented originally.
Tony, I agree with your first post ... 1050 +/- 50 as a good place to have your idle.
Mine has some work under the hood too ... SISF's power cams, 36 mm ZX1000 carbs and your stick coils.
And ya, the cold idle is cool
