It's probably not a serious problem but it IS a problem. If the idle speed is WAY too low, it can stumble a bit.
After it is thoroughly warmed up, tweek the throttle open just a TINY bit, until you can just BARELY notice an increase in idle speed. If it also seems to run smoother when speeded up slightly, then your idle adjustment is probably too low. Adjust it up a bit with the knob beside the carb.

First, visually check for cracks or other obvious damage.......including checking for holes/modifications to the air cleaner or the box. Then look to be sure there is a plug in the end of the air box drain hose.
If that doesn't yield anything, get a can of spray carb cleaner (Gumout). Spray a little around the OUTSIDE of the vacume hose going to the petcock; also the boot going into the engine; also the outside of the air box and the drain hose in the bottom.......if the engine speed changes, you are spraying it on a spot where there is a vacume leak.
If the idle speed is not the problem and you don't find any vacume or exhaust leaks, remove the air filter, start the engine and spray the Gumout directly (as possible) into the carb intake, slowly at first and then fast enough to kill the engine. Turn off the ignition and replace the air cleaner and covers. Let it sit for about 15 minutes then go for a ride.
PLEASE print this message out (and maybe my earlier one too). Refer to it (them) until you have checked out all the things I mentioned. If none of that helps, then you need to ride it for 100 miles or so to see if the cleaner does the trick. If not, you need to SERIOUSLY consider taking it to a shop.
Based on your questions and answers, I do NOT think YOU should be taking the carb. apart.
Sorry but I just don't.
