fuel level/float height? was created by kayodash
I've looked everywhere for this information. And can't find it anywhere. Does anybody know the correct fuel level and float height for a 1984 KZ550f2 LTD? I've got 3 different on my carbs. And leaking between 3&4
#1 is 10mm #2 is 11-12mm 3&4 are both about 7mm which happens to be the ones leaking from overflow tube.
Attached is a picture of the carbs from a picture on eBay.

What is clear tube test? I've used a clear tube at the bottom where the bowls drain and measured from where the bowl meets the body. That's how I got those measurements

You need to check the needles and seats and clean them if dirty. The level should be just below the flange on the bowls. Approx. 1/4"below the joints.

I've cleaned them and replaced with new ones. It doesn't "leak" anymore but after a few minutes of the bike sitting after it's off the tips of the overflow tubes. Both of them start to form a drip. But it just isn't ever heavy enough to drop, in fact one of them end up evaporating inside the tube and it's literally just the tip that's moist. Is that normal?

No. Don't bend the tang on too much of a angle. It will cock the needle to one side and cause a leak. Bend the arms with the tangs level, then fine adjust using the tangs.

Make sure the fuel valve stops the flow of fuel when the engine is stopped.
The service fuel level measurement is usually done in relation to the bottom of the carburetor body.
A standard measurement is typically 3.0mm +/- 1.0mm below the bottom of the carb body.
Edit: the 550 is different. see reply below by loudhvx.
If adjustment is needed, instead of bending the tang, I set up a simple support for the float, then flexed the tang X number of times, then re-checked the fuel level.

I don't have a manual for the shaft drive models, but the 82/83 KZ550H (gpz) models use very similar carbs. (They're all Teikei TK26 CV carbs.) So the fuel level for the KZ550H should be the same for your KZ550F model.
In my signature there is a page with manuals. Look at the "factory base book" for '79 - '83, 99924-1018-06.
Page 381 (388 of the pdf) shows the service level for the fuel. It also shows a float level to make it easier to setup initially.
I'll attach some snapshots of the page.

I don't know much about the set up of your particular carb and fuel delivery. On my 79/650 two things add to the equation.
1. the petcock is vacuum and a bad diaphragm will cause more gas to spill into my @2 carb
2. the @2 carb has a fuel pump accelerator on the bottom, again with a diaphragm that can leak more gas into the #2 carb
Wondering if your ride shares similar characteristics?

Thank you all for your replies, so 7mm should be ok if its 6mm plus or minus 1. So #1& #2 would be lean... Which doesn't make sense to me why there would be gas at the bottom of the overflow tube. I checked it This morning and the tube between 3&4 was dry. 1&2 was wet. But like I said it never gets heavy enough to drip. I've got cardboard underneath it. I remember looking at the floats in 3&4 and seeing the tang was crooked. I think that may be my issues in all carbs I'm not sure.

Could be. Also spdygon had a cracked overflow tube. He soldered it. Fixed.

Yes, lately carbs have been showing up with cracked overflow pipes inside the carbs. The alcohol in modern gas is destroying our carbs.
