I respectfully suggest you correct the fuel leaks before going any further or you may end up getting hurt and losing the bike. Ed

Quote ...........................................The airbox coupling things dont fit to the carb, its like the whole thing has warped and its all off by a half inch but the carbs are attached to the engine just fine
I'm surprised you got it to start at all if the airbox is still not hooked up. In order to run the engine has to get fuel and air in the right ratio and if the airbox is not hooked up and the back of the carbs are open then you are getting to much air in relation to fuel.
After you get the petcock and fuel leak issue sorted out I would suggest wrestling with the airbox to make it fit.

well the carb on the bike is not what came on it, its slightly larger and does not fit the air box so i went ahead and bought the pod filters seeing as it was my only choice. I also got new jets to go along with that. I was told there was a stage 2 jet kit installed already but i dont know if i trust the P.O.

Well now....that's a bit different than simply not having fuel get from carb to cylinder.
First rule with a used bike is that the PO always lies.
After you get the leak sorted out I would suggest that you need to identify what carbs - some photographs of the carbs should help with this. You need to identify what jets are in the carbs and here somebody more knowledgeable than I may suggest suitable jetting for pods and you need to confirm if you are running with pods and also what make may help
Good luck

after looking at the specs for the stage 2 jets and pulling mine out it turns out he was actually telling the truth! but im going to put the new stuff in just to eliminate any possible headaches. Before i wasnt getting any fuel come out of the float bowls and now i am. all the pictures and things look like the carbs are mikuni bs32's. so thats what im going off of.

well i installed the pod filters against better judgement and the bike fired right up, just had to tune in the idle a little bit and i went out ridding. When i came back and parked it, it sat for about 10min or so and then when i went to start it it wouldnt start and i heard loud clunking noises. I checked the starter and it was fine...my starter clutch went out after my ride of like 2 or 3 miles...wouldnt ya know when you finally get one thing fixed another breaks. Oh well i only payed $400 for the bike and have $136 in tune up and the pod filter set up. I guess the $85 for the starter clutch still isnt too bad for over all costs. After everything is fully operational it will be stripped back down for paint, a nice flat black then tear up the roads of VA, NC, and WV lol
