Carb woes, I guess?

[rebellion ind]

Let me start out by saying that my bike ran fine last year. Since then I have done the following:
-Drained tank and float bowls last winter
-Fixed, Derusted, painted tank
-Cleaned petcock screen and replaced rubber piece in petcock
-Added new fuel line with in line fuel filter for each line running to carb
-replaced throttle cable

My issues- Bike ran poorly the other day after adding new fuel line seemed to not be getting fuel to one cylinder and sputtering so I left it alone with the fuel valve open. Came back to it last night, I started it an it ran great but I didn't have time to ride it, so I started it tonight and it fired right up. I let it warm up for 5 minutes and then took it out on the street, as long as I left it as 1/4 choke it ran fine but if I removed the choke it sputtered and threatened to stall. Ran it for about 10 minutes then it started sputtering and running on one cylinder. I limped it home and had it run on both cylinders sporadically on the trip home. I looked at the fuel filters and saw the filter for the good running cylinder was nearly full of fuel while the sputtering cylinder had next to no fuel in its filter (I do know that when I left both filters had plenty of fuel in them). I removed the filter to make sure fuel would come out the hose when open and it does, so why doesn't the filter fill up? I have the filter's flow going in the correct direction and the hose doesn't appear to be kinked in anyway, so I am at a loss for what is wrong and what I should be doing.

What sort of filters are they? Some of the cheaper cardboard style filters will not allow gravity fuel flow (designed for fuel pumps).

Take them off and see what happens (sounds like you have a clean tank / petcock anyway).

Well the filter that runs to the carb on the left side fills right up with fuel, its the right side that doesn't take any on. I guess what I should do is remove the line after the filter and see if I get any flow that way, if not the filter has to be plugged on the other hand if it runs through then there are issues furher up the line, I guess.

Remove the pos filter, open the garbage can, and place them in it. Close lid. Those filters should NOT be on a bike! If they were so goddamned great Mr fuckin honda would have put them on the bike himself! Those pieces of shit restrict fuel flow, especially to the right side carbs. They cause air locks as well. Even if they had no filter element at all in them, they would restict flow, as they reduce the fuel line size where they install into the line. If you want to see fuel flow, use clear lines. You now need to replace the lines again.
Just last night, a customer comes and picks up his bike. He had those little inline filters on his bike. I left them on, as I had nothing to do with that part of the bike. He leaves with the bike, and I go in for Supper. Half way through my meal the phone rings. He's stranded down the road. I get up to go get him. I get there, and he says the bike just sputtered, and slowly died. I look at the filter and it's empty. Pull the line and fuel flows. The filter was air locked! Got him running, and on his way. Inline filters are not needed. You have a screen filter, and a water/sediment trap in your petcocks

Well I pulled off the filters but it didn't seem to help so fellow DTT member "Stout" helped me pull the carbs and we found the needle to be weak on the one side so we swapped needles between the two carbs to verify and sure enough the left side then wasn't getting fuel, so we swapped them one more time just to make sure and then the right side ran fine with the good needle, but so did the left side, so I don't know if we knocked some crud loose or what, but as of right now the bike runs well. I did however order two new Needle and seats just to be on the safe side and the filters are sitting on the floor in my garage.
