Hello, dragbikewilli, and WELCOME to KZr! :cheer:

:unsure: Are the carbs in question the same model carbs that originally came on the bike? And exactly which specs? Air box or pods? Oem exhaust or 4>1, and what baffle, if any?

Am thinking "specs" would typically include main jet, pilot jet, jet needle, and default pilot screw turns.
Anything else? :unsure:

Good Fortune! :)

Float height will hopefully get in the ball park toward correct fuel level.

Absent an FSM for reference, would "guess" service fuel level should be 2~4mm below bottom of carb.

Pump rod spec is in the B4 supplement manual. If it hasn't been fiddled with, don't touch it. They were good right from the factory. The 28 pumpers were the best carburetors Kawi ever put on a KZ1000.

These carbs got jacked with from a shop that didn't know what they were doing and got'm all messed up so I'm having to fix a mess! I have a bike shop in Lubbock,Tx and from what I gather on these carbs I can understand why Kawasaki got away from them...I'm getting closer, just having a tuff time gathering info and so for now,I'm mostly going by the seat of my pants..Did find out that they will not take a large squirt from the pumper.Trying to save time by finding info!Making some head way and now if I can just find what the adjustment is on the pump rod I'll be done !...Ye-Ha!...Once I get this one done I have another bike just like it and then I think I will classify myself as a guru!."HA,ya right"!..lol.. Well, thanks for the help anyway!

Hey Willie, I have the b3 supplement. I think they are the same as 1980 b4 on the pumpers.
Here is a shot of what you are looking for. Good luck.

I might have a rack that hasn't been jacked with. Holler if you need them.
