Dump the gas and replace with fresh. Pull the tank off and remove everything in there. Pour that through a coffee filter, and see if there are any chunks in it. you're looking for rust and debris which can clog injectors.
If it's not running well, it's typcially going to be a fuel related problem; in your case it's more likely that it's electrical as you have a strong odor of unburnt fuel you're dealing with. Could be one of the coils is wet. The stick coils sit right on top of the spark plugs. The one furthest downhill when the bike is on the side stand is the one that has the greatest chance of collecting water and grounding out.
since you'll already have the tank off, it's not that much more difficult to pull off the airbox and access the plugs. Good time for new plugs, too.
