1981 gs 1100 2 carbs leaking into air filters after carb cleaning.
Did you leave the petcock on PR too long? Is your petcock working right?
Otherwise, your float needle seats might be leaking. Just how did you clean these carbs ?

They were fully disassembled. Blown out and re assembled.

What about the Petcock?

That isn't cleaning them. Do it correctly ONE time. It's a lot less painful...
You've been here a year... was the bike sorta running before and you just got ambitious?

Honestly, I haven't had it running yet. It has spark and compression. The person I had clean carbs has 12 maybe more GS bikes. He broke carbs all down in front of me, pulled jets and made sure they were clear and sprayed out everything, tapped out the pins holding floats on and all. I'm no expert here but for just a cleaning I'm not sure what else could have been done. It wasn't a rebuild or jet job. Which he recommends because I have 4 new cone filters and of course it would need Jets to run good with those. But he has stock air boxes all over so working with my budget at the moment I was hoping to hear her run before investing in carb kits and jets. To answer your question though yes I just got ambitious about getting her going in general. After research here I might have thought it was the petcock issue but didn't understand why only 2 of the carbs were leaking into air filters. Maybe that still is what it is, I really don't know. I believe he said it was the float needle seats. I just wanted more input, since he didn't mention petcock issue.
That's a half ass carb clean. Read the tutorials and you'll see that you should soak the carbs for at least 24 hrs (mine ended up still being dirty and had to reclean them so I'll go for 48 hrs minimum next time), clean with carb cleaner, then blow out the passages with air.
I think you have CV carbs which I know nothing about, but the float valves may need replacing if they're too worn to hold the valve shut.

This guy with the dozen gs bikes was not being straightforward with you. These CV carbs have tiny passages cast/ machined into the carb bodies where fuel and air have to get thru. Once gummed up they need full disassembly, then a 24 hour dip, or a good guy with a ultrasonic cleaner. Blowing air into gunked carbs probably just drives the gunk deeper. Then they need new o-rings during reassembly. Any shortcuts will likely lead to poor performance and drive you crazy. As was stated, do it right the first time.
Try to get the stock airbox/filter setup for your model.cuz it will make your life easier. Later you can boldly leap to pods if desired. Avoid aftermarket carb kits- not needed: head to cycleorings.com for the new o-rings,etc.
But since you have spark and ignition, bike should be able to start and run at low speeds with properly cleaned carbs even with the pod setup.
A replacement vacuum petcock -maybe $60- is always good insurance . Float needle seats tend to dribble gas with bike off , it's nice to have the petcock block this action.
