1984 GPZ750A3.
1. Does someone have the float height spec they can give me?
The KZ750 Four manual .pdf I downloaded says 36.5mm + or - 1 mm. I just want to double check that is the same as the GPZ.
2. Any tips or tricks for accurate measurement? I've watched several online videos on how to do it and they are all slightly different.

Would focus on achieving correct fuel level instead of measured "float height."
Setting "float height" to a dry upside-down measurement is often unreliable toward achieving the correct fuel level, especially in old carbs.
Would use the clear-tube method, incident to which the "float height" may be adjusted to assure the correct fuel level, described in the Factory Service Manual as the service fuel level.
The goal is to achieve correct fuel levels, regardless of whatever the upside-down dry "float height" measurement happens to be that results in the correct fuel level.
Even when "float height" is set to prescribed measurement, the resulting fuel level may be incorrect via the clear-tube test, thereby necessitating re-adjustment of the "float height."
Good Fortune!

Patton's absolutely right. Trying to fiddle with "float levels" won't buy you much at all. Keep in mind that floats will not all weigh exactly the same or have exactly the same buoyancy. The floats control the FUEL level, and that is what matters. Use the clear tube method to adjust the FUEL level to the spec for your bike. The Kawasaki Service Manual gives the spec. Ed

Here's a site w a manual. Scroll down & click "The Bible" link. It isn't the greatest pdf as some of the pages didn't get copied very good.
mbsween.bike-night KZ750L3 page
The ZX750-A3 specific info is in a supplement near the back. I'm pretty sure the service fuel level spec is 3.0mm +/- 1.0mm below the bottom edge of the carburetor body (pg 317)(pdf pg 307).
Note: not applicable to the GPz, but some of the wiring diagrams are mislabeled in the links.
The 1981 Ltd is an H2, the 82 is an H3, & the 83 is an H4. search tags mbsween KZ750L3

In addition to what has been suggested, make sure the carburetors are level when using the wet float method. And if you find any individual carburetor needs adjustment, I like to measure the height of the tab using a feeler gauge as a reference. You will find the slightest adjustment measurable with a feeler gauge makes a difference. This way you can judge how much change you make between adjustments and it can help guide you on the next adjustment.
