Bike is dying while riding

Hello everybody, i bough a bandit gsf600 1998 from a guy that had a bike for a while but never rode it. I drove the bike for good 2 weeks with no problems, and yesterday i've started to have so issues. While i was riding it basically stalled on me 15 times whiting a mile. I would ride and give it a gas, at some point when you give it a gas it looses its power and dies, then its really hard to power bike back on. So i though maybe my carbs need to be cleaned. Took it apart and air cleaned everything (4 carbs). Put everything back together, couldnt start the bike at first but then it did start. Noticed a thing, when ever i have a choke open it doesnt bring RPM, only when you give it a gas, after closing a choke, RPMs dont drop and stay at 3-4k rpm. Though ohh well, gotta go to a mechanic, left my house and it stalled a mile away from my house, same issue, loss in power and then dies.

Having no clue on whats going on, and if any of you can help me here, please reply back.

Air cleaned?? sounds like you might have a fuel delivery problem from tank possibly. now it sounds like a vacum leak also. carbs are verrrry delicate on bikes and even though it is not a H/D lol. return to scene of crime and look for good fuel flow from tank and look for something you might have p/o when you ( air cleaned) for a start

Was it ridden much before you bought it? Was there old gas in the tank? Did you check your fuel line filter? Did the filter look good, or just ok?

If you eliminated the carb as a problem, then it sounds likely to be the tank (sludge, water or bad gas) or the fuel line/filter (is there an in-tank screen?)....that is, as long as the carb was reinstalled correctly.

Noticed a thing after installing carbs back in. After turning on the bike, i let it warm up with choke on, after closing the choke rpms don't drop, same thing if you just give it a gas, rpms don't drop. Trying adjusting throttle position, its messed up because, when its running while adjusted, its going to stay at 1.1k, as soon as you give it a gas, it rises and never drops, you turn off the motorcycle and back on, its idling at 3 now, all messed up, checked the cables, they look fine to me.
Today we decided to take a part a cockpit under the tank, and filters were fine, only thing i noticed is that fuel line i was able to blow through, and air line was stuck, i don't know why, there was nothing that would clog it, so i don't know why air line is not blowing air through. After installing the cockpit, i didnt mess with the throttle body anymore cause all i wanted it for the motorcycle to at least start and idle, well i did start and idled for id say a minute and then stalled by it self. I turned it on a gave it a little gas, stalled right away. Next time i gave it a gas slowly and it brought the RPMs up but then dropped and stalled again.

It was not ridden for a while before i bough it, but the seller made sure that it was in the running condition. After buying it, we went and filled it with new gas all the way in, plus i added some Seafoam in gas tank for some cleaning. My step dad got a really old fuel tank that had idk what gas in it and poured a new one in, it should have mixed up. After getting home i filled the tank to full with some more fuel, the problems started after i rode 125miles since i filled it and got a quarter of a tank left.

I'm thinking that your symptoms are similar to what I experienced when I got a used Kawasaki bike from a guy. It ran fine, then didn't - unless I cleaned the carb. Then it jammed again. Turned out to be rust in the tank that took time to clog the filter and/or float. My rust was from the gas cap area, at the top of the tank.

Of course, it is always a "red flag" when the seller is the one making sure it is in running condition....not necessarily due to bad intentions, just that it ain't the buyer. You seem to know enough to find this problem, and it ain't black magic, so good luck. Let us know what it turns out to be.

And, of course, I have to ask - do you have the service manual?

Yes, i do have a manual.
Update: i changed the oil and new filter so far, after work i will pull my plugs out and sandpaper them to a clean state, ive compared mine to anoyher picture and mine dont look right, then i will try again and do a carb clean but yhis time with acetone. I assume that when give throttle and it dies is because of a fuel flow, ill test the fueltank petcock, and in on position will try to blow in tge air hose that should let the fuel flow since it has a pressure plate. If that dont work then its a tune that got messed up, because i noticed a screw on the bottom of each carburator, on tge bowl part, and on 2 carbs they are all the way in, and other two are half way in, i dont know what those screws do so i font ness with them, they dont seem to be connected inside the bowl, and i have no idea why my carbs have them, when disassembling my carbs first tine i noticed two fat nipples tgat are interconnected between 1 2 carbs and 3 4, thry were open and had no hoses on them, when i took the carbs out it was spilling fuel, so maybe they shoukd be connected to regukate fuel more ?
