I'm not sure this can help you or not but here goes.
I wouldn't adjust for maxinum vacumn for two reasons. First, when I did tune for maximum vacumn with my79 GS1000, it would stall when I cracked the throttle from idle. I had to reduce the vacumn until I had the preformance I wanted, even if it did carbon up #1 and #2 plugs a bit faster than #3 & #4.
On another bike I rebuilt I assembled and adjusted the carbs lean without guages and had it run hotter than I wanted. In fact I could smell the heat unless I ran a bit of choke. I ran it like that very little and later a valve spring broke. The spring was new when I did the engine assembly and tuned lean. I figure the heat led to its giving out.
I am also curious what your bike would run like through 5000 if you pulled a bit of choke.
