Somewhere I read that running the bike dry won't really get all the gas out of the bottom of the bowls. I have a 2-foot length of fuel line (I think it's 3/16") that fits on the nipple at the bottom of the float bowl. That and a clean tin can will make sure that the bowl is completely empty. Stabil instructs you to run the engine for a couple of minutes to make sure the stuff gets through the carbs. Then I drain them.
