The GSXR throttle bodies would not physically fit in the 83 GPz750 (ZX750A1) carb holders, but do fit in the KZ1000J/K/M carb holders.
I have no idea what carbs each one uses (I might look later).
According to Z1 Enterprises:
Fits Kawasaki KZ650H2/H3 KZ750E1-E3/F1/H1-H4/L3/N1/N2/R1 ZX750A-A3/E1/E2
(The E1/E2 are the 84/85 750 Turbo)

Just for grins (and since they happen to be in the house) I just tried again to put the GSXR throttle bodies in the GPz750A1 carb holders, and short of using a hydraulic press or a BFH there ain't no way that they will fit. They do fit in the KZ1000J/K/M carb holders, but it's a tight fit.
I also have KZ750E (1980) carb holders and they are the same size as the GPz750A1.
Maybe they make BS34 carbs with different spigot sizes, I don't know.
I did a bit of searching and discovered that the BS34 Mikuni carbs have been used on everything from a 250 single to the GS1150, including the GPz750A and KZ1000J/K/M, so my guess is there must be different models of BS34 carbs with different spigot diameters.
3 am and I go out to the garage to check:blush:
The KZ1000J/K/M carb holders that I bought from Jeff are to large for the KZ750E carbs that are sitting on the bench, so although both the GPz750 and the KZ1000J/K/M may use BS34 carbs, there must be different models of BS34s.
Now that I am confused, I'm going to bed and hope someone has this all figured out by the time I wake up
