All you really need is carb cleaner, compressed air, either from a compressor or canned air, glass jars to soak the jets, tooth pics and small brushes.
It's usually a good idea to keep the jets for each particular carb in separate jars. In other words, have a jar 1 for carb 1, jar 2 for carb 2, etc..
There are a bajillion videos that show you how to clean them.
My personal fav is a guy named MrMaxStorey on youtube. He has a knack of explaining things in a simple manner.

Dropping just the bowls isn't enough as you will need to remove the top to get the needle valves out. Plus, I can pretty much guarantee you will drop a washer, spring, jet or something if you try to leave the carbs attached. Finding something that small in the engine compartment area can be murderous. I speak from experience.
"IF" the PO did it right, the inner screws should be facing out at approximately a 45 degree angle, like the ones on the outer carbs. It's kinda like playing where's Waldo. But they are there.

Nope. Keep at it. They will come off. If the carbs haven't been off in a long time, they are a bugger. You will swear there's something else holding them, but it's just the boots are adhered to the intakes. Rock them back and forth, then front and back. If you have a rubber mallet, GENTLY tap on them. I've found getting #1 or #4 loose will help the rest. Sometimes warming up the boots with a hair dryer helps. I've even pried them off, but you really have to be super careful doing that.

well you were right just alot of pulling and a flat head for leverage. I dont have access to compressed air right now whats next best? should I take everything out and let it sit over night in some gas or seafoam or am i ok with a needle and carb cleaner cleaning it out?
Its pretty gummed up in there pulled the jet out that had a way to get a wrench on it and i could hardly see out the 6 holes. how do i get the others out?

Take a look at this post and it will help you describe some of the things you're looking at. Most auto parts stores sell a parts cleaning dip can where you can soak an individual carburetor body in overnight.

See if you can get something like this in your area. After soaking, you can use the spray carb cleaner to ensure that the passageways are all cleaned out.

Be careful. You know all of those "this product can cause cancer blah blah blah"? This stuff actually will. Use gloves, go slow and don't spill.
But essentially, get all of your rubber seals removed from the components. Break down the jets, needle valve, floats, air needles, and then take all of your solely metal parts of the carbs and let them soak for 24hrs in the carb dip. So then,you need to make sure your venturis and other passages in the carb body are clear. Make sure your diaphragms are in working order.
Take your plastic parts and make sure they're clean and ready-to-go.
The next day, assemble everything back together. Make sure everything is free and clear (like the jets). If they're not, use some of the copper from wiring to clear it.Put back on motorcycle.
After all of that, you want to make sure you use new fuel lines and a new filter. Flush the fuel pump with new gas. Not doing this is like putting on dirty underwear after a shower.
Then you'll want to sync the carbs.

100% agree with everything Conrice and IDoDirt said. As to the not having compressed air question, go to CVS, RiteAid or Office Depot and get a can of compressed air. It's the kind you blow out computer keyboards and electronics. One large can should be more than enough to get the job done.
