Assure ignition timing is correct, F mark aligned with case mark at low idle RPM.
Use strobe type timing light to watch advancer move back and forth as RPM's are varied by blipping throttle.
Would also check/adjust valve clearances to specs. And perform compression test.
Remove plugs, visually inspect quality of spark, and install brand new plugs per KHI specs.
All of the above before addressing carbs.
Good Luck!

I saw in another thread where someone put terrycloth wristbands over their pods. Seems like a decent stopgap until you re-jet.

I put pod filters on my 1982 KZ 550 LTD and it won't start cold....
Would it start cold before pods were installed?
Some KZ models are reportedly very tempermental about starting unless the airfilters in oem airboxes are perfectly installed.

Another thing to consider is the fast-idle adjustment. If it's set properly, you can start without any throttle blip. Here's a mod to make it easy to adjust without taking the tank off. It's for the 81 gpz, but the LTD, and most years for the Standard, carbs are identical.

Also if you're running pods or an aftermarket exhaust, you'll probably want to go up 2 to 6 main jet sizes and maybe even 2 to 4 sizes on the pilot jets depending on the exhaust and pods flow. I drill all my own jets. There are many sources for mini drill bits on the internet. I found the cheap drills at Menards have chucks that close all the way down.
The TK22 work very well without the airbox and jetting is simple because they are not CV carbs. It's just a matter of getting the choke flaps working perfectly.
I think someone tried sealing the flaps on the choke plates all the way shut. That way you manually control the choke opening as you hit the starter. That's the same principle as the hand-over-the-airbox-opening trick. Just slowly lower the choke lever (opens the choke) while you are cranking.

If I try to drill out the jets, how do I determine what size drill bit to use? Do jet #'s correspond to millimeters or some other standard? All I have are the pod filters. The exhaust is stock. What size drill bits would be recomended for this?
As far as the ignition timing goes, I don't know if it's adjustable I'll check into that. I stock ignition on the bike. Electronic, no points... is that adjustable? Also, I think I could benefit from a valve adjustment. I'll have to look into things more when the weather gets a bit warmer.

1 inch equals 25.4mm and the mini drill bits I use come with thousandths of inch markings in the index.
The difference in flow for two different jets with the same number can be attributed to other factors such as the length of the jets bore, and the depth at which the orifice sits in the bowl.
For the most part, the ignition is not adjustable without elongating the timing plate holes.

If you have carbs that look like this, then they are TK22's as Lou mentioned. You can go to www.buykawasaki.com and find your year and model, then see the exploded view diagrams, but you'll need the jetting Lou recommends, as his bikes use the same carbs.
