Any leaks in vacum pipe from carb to petrol tap
SOURCE: Misfire and backfire at low rpm, runs rough at low rpm
You did not say whether or not this was a carburater engine but from the sound of it one of your jets may be sticking, a good cleaning of the jets will most likely fix the problem, the likely cause is a small build up or piece of debris on the jet.

Hi Jwelden,
Have you checked the float level in the float chamber?
I guess you may have to reset the float pin adjustment, its allowing more gas to pass through thn required and thus the overflow!
Not bad too, when you are working on the float assembly take the opportunity to blow out the fuel line from petcock to the carburator via the seat for the float pin,any foreign particals there would stop the float pin to seal up and thus overflow.
Fit in an inline fuel filter , this will help keep out the dirt or whatever.
Hope this helps.

The fuel tanks are common to rust through, maybe that is where the dirt is from.

when you get the bike started you need to adjust the pilot air screw. here's how= turn in clock wise until engine falters(mark that spot with a pin)then out counterclock wise until the engine falters(mark that spot also) then put the screw in half amount adjustment of the two marks.that will take care of if it is to lean or to rich.make sure the engine is good and warm before doing so.
