AND..seeing that the side draft emulsion tubes are a common wear issue (from what you and Mike were talking about) used carbs might be just as worn. I'm gonna take a guess here and say that before you got them all cleaned out, it was running lean from being all gummed up, and needed that extra fuel. Now that the rest of the carbs is working right, it's too much fuel. Maybe once this is ironed out, you'll get better mileage! I'm hoping that once I get my bike back together and everything RIGHT, the same will happen!
