Hi, Ive sorted my other problem, it turned out that there was some junk blcking the main jet on No3. Anyway i have took those carbs off and put the ones that are supposed to go with the bike.The only problem i have is that No1 (far left cylinder) leaks when i put the bike on the sidestand. On the mainstand its fine.
Unfortuantly i cant live with that problem as its too awkward for me to put the bike on the mainstand everywhere.
So i dropped the bowl off, looked for crap, worn float needle, and all seems fine. I held the float closed and ble thro the fuel pipe, and it seems to make a good seal...
Could it be:
-worn needle valve- but not visible to the eye
- wrong float hieght ( not sure what the hieght should be for a kawasaki GT550 G7) ( same carbs as on a kawasaki ZR550 B1- B9- i think)
- faulty float

Im sooo close the bike runs good, just this one problem to sort out before i can wrestle the air ducts back on the airbox side!.
 
The carburetor float is not adjusted correctly. The float level is set too high.

The float needle and seat should be OK as you said that it only leaks on the side stand. But it doesn't leak on the center stand which tells me that the float needle and seat are making a good seal.

You can check the level on the bike. Get a clear hose and attach it to one of the drain fittings on the float bowl. (Start at one side and go to the other.) Level the carbs and supply fuel to them. Open the drain screw and watch the float level rise. When it stops, measure from the level in the tube to the top of the float bowl. On some Kawasakis that don't have drain fittings you will need to take a screw and drill a hole through the center and insert this where the drain screw is. There are only a few that don't have drain fittings. Check all the levels and adjust them or replace the float valves as needed. You want to be running about 2mm below the top of the float bowl.
