This may get long I was and still am having idling problems with my 95 GSX-600, so here is what all I have done and checked.
Cleaned Carbs, Emulsion tubes, AF Needle, Pilot Jets, Main Jets, Measured and Adjusted Floats, Needles are on the 3rd clip. All O-Rings are accounted for and in the proper place.
New Fuel Line and Filters, Fuel Petcock is working.
Checked for Vaccum Leaks around intake boots.
New Air Filter
All New Spark Plugs are gapped to specs.
All Spark Plugs have Fire.
Took the head off and checked the valves, all were within specs except Cylinder number 4 exaust valves were real loose.
Carbs 1 and 2 are synced together.
Could not get carbs 3 and 4 synced other than visually.
After Cleaning the Carbs completely and checking all of the above I was able to get it running good enough to check the plugs and see how the AF mixture is, Cylinders 1,2,3 are perfect with a light tan color, Cylinder number 4 plug is shiney clean with fuel/oil on it, not sure which. Also when I touch the headers after warming it up, 1,2,3 are hot to touch but #4 I can put my whole hand on it and hold it there, thats how I found out it was #4 giving me problems, this would also explain why I could not get carbs 3 and 4 synced together with the DIY fluid method. When I took the AF screws out of the carbs the first time I paid attention to how many turns they were out and the screw on Carb 4 was leaned all the way in.. now I know why!
Here is what I have narrowed it down to
Valves?
Or compression?
Could be plug? or ignition, but I have checked and double checked the fire and changed plugs? This stuff is not hard it`s just a process of elimination!
I know I should have adjusted the valves before I did all this but I know that once the engine heats up they will loosen up a bit and I didnt know at the time whether it was valves, compression, or carbs causing it to idle rough. I need to adjust the valves next but these valves do not have screw type adjustments, I read somewhere about having to shim valves? but I havent been able to find clear instructions on exactly how to do it and what tools I will need. Have any of you ever adjusted valves like this before or can you send me a link on how to do this?
Here is a short video of it running

Here is a pic of the valves, should have taken a closer one..
