I use a hair dryer on low to speed drying. It sounds like the filter isn't flowing air for some reason. Too much oil is possible. My cousin oiled his TwinAir with a whole bottle of airfilter oil. He couldn't get the bike to run. When I found the filter dripping and weighing about a pound we cleaned and re-oiled it and all was well. Also, clean that filter under your seat that cleans the air to the carb diaphragm. I use a piece of foam that I cut from a Briggs & Stratton airfilter element that you can get at most hardware stores. oil it like you would your air filter.
