New KZ owner!

I recently bought my dream bike, its a ‘77 KZ1000 LTD. It appears to be mostly stock, with the exception of aftermarket air cleaners, and a Vance & Hines 4 into 1.
It runs fairly well, it’s running a bit rich, it only likes to be off choke when your moving, when coming to a stop it needs a bit of choke to keep from stalling. I looked at the plugs, they are pretty black, but no thick build up. I’m going to switch to non-ethanol, & see if that helps any. There’s a brown liquid on the bottom of the carbs, it does seem oily, however, from reading posts on here I believe it may be the float bowls. The previous owner said he went through the carbs, and they were in good shape. He seemed like he was pretty capable, but you never know. He did tell me when I bought it that it was running rich, and that he felt like the carbs needed to be synchronized.
I’m definitely open to any ideas, suggestions and advice. I’m a fair mechanic, but most of my experience is with cars, so I’m definitely here to learn.

How about a photo of your bike?
I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.

Here’s a manual, and you need to search evilbay to find a 1977 Kz1000 LTD B1 supplement manual.

If you need to add choke, that is generally a sign that it's running lean, not rich. The choke circuit on these carbs adds fuel.
When pod filters and pipe are installed, that often requires the use of larger jets. It's possible that whoever installed those did not bother to rejet the carbs, which would tend to make it run lean.
I also recommend removing the carbs and inspecting and cleaning them. Compare the jets you have to the original factory size and see where you are.
Also, there are air corrector jets that have been discussed here that many say help with the low speed response when using pod filters.

As DOHC mentioned air correctors jets are great for fixing lean conditions caused by installing pod filters. Read this post

Also you need to know what circuit is rich. The pilot, jet needle, or the main...

As for shims. You will have to check them, if they are out of spec then the only way to change lash is to find out what size sim is currently in that valve bucket and look at the chart in the manual. It will tell you what shim size to use to correct lash. Then you can hunt evilbay for the shim recommended from the chart. Only use OEM Kawasaki shims. Also check with your local Kawasaki dealer. If you get the right service guy they might be willing to swap shims with you.... Rick H turned me on to that lead. I got cozy with the parts guy and asked him, he said sure, they have draws full that no longer get used. But they don’t sell them but will trade you for the size you need. One for one.
When you pull the shim off the top of the bucket the shim size will be on the bottom, it’s that way so the size isn’t rubbed off by the cam lobe. DO NOT rotate the engine without a shim in place.
This is the tool used to replace the shim.
