I have a 1980 Kawasaki KZ750 Ltd. I bought new. I recently managed to get it out of my garage after 28 years and put it on the road again (2010). I feel like a kid all over again. Since I have acquired 3 78 KZ1000 Ltd, 1 1981 KZ1000 Ltd, and another 1980 KZ750 Ltd. Love the LTD's.

If you want a free copy of the manual, pm me your email address and I'll send you a copy. The float height measurement is only to get things in the ballpark prior to doing the clear tube method.
+1 The clear tube method is the only accurate way to set fuel levels. Ed
Amen.
The perfect dry float height measurement is whatever measurement results in the correct fuel level as evidenced by the clear tube test.
The dry float height measurement is wrong if it doesn't result in the correct fuel level as evidenced by the clear tube test.
Fuel level is the critical element in carb function.
As long as the fuel level is correct, the dry measured float height is inconsequential.
When each of the four carbs has the correct fuel level as evidenced by the clear tube test, it's not unusual to see variances among the dry measured float heights.
The fuel level specification is often 3 mm below the edge of the of the carburetor body.
Such as KZ900 (26mm carbs).
The FSMs for different models provide the specific measurement range for an acceptable fuel level.
For example, some models may range from 2.5~4.5 mm below the carburetor body.
Such as Z1 (28mm carbs).
1978 KZ1000-A2 (26mm carbs) 3±1 mm
1978 KZ1000-D1 (28mm carbs) 4±1 mm
1979 KZ1000-A3 (28mm carbs) and 1979 KZ1000-D2 (28mm carbs) 4±1 mm
So why goof around with the dry float height measurement?
Because it may sometimes be useful as a preliminary ball-park setting before later fine-tuning the fuel level by performing the clear tube test.
When the carbs were brand new, and before the now aged float mechanisms got worn, bent and banged, the dry float height measurement was more likely to result in a fuel level being closer to specs.
Of course, the "tang" adjustment on the float mechanism is used to achieve the correct fuel level as evidenced by the clear tube test.
Good Fortune!

Good Fortune!
The carb you have posted here looks like the Keihin CV's I had on my '80 KZ750E1.
The butterfly choke plates are not on the Mikuni CV's if I remember right.
