Here is a good writeup on it:

The more open the pipes are the more air flows, the more air that flows the more fuel you have to add or it will be a lean mixture. Since you put the stock pipes back on you reduced the amount of air flowing through the engine so you must also reduce the ammount of fuel. First step is the idle mixture screw adjustment, if that does not do it then you will have to look at the jetting.

I'm not sure I should adjust it. How much should I turn the idle adjustment screw if I do?
If it's running too lean, how will I know?
Sorry for all the newbie questions.

Thread the screw in until it bottoms, go easy so that you don`t damage the needle (fragile).
Back the needle out about 2-1/2 turns, that should give you a pretty good starting point.
I also suggest that you remove the float bowl and clean out the bottom of the carb, you may simply have some debris preventing the needle from seating, causing an overflow of the carb.
