Sounds like crap in the float bowls generally caused by water in the fuel which causes rust to form inside the tank. Since your bike was in the rain for a few day water may have also lodged in the top of the spark plug caps. This does not evaporate easily as you would expect when the bike heats up as it creates a seal and stays around the connection between the coil leads and the cap. Twist the cap off and maybe cut 10mm off the eads and spray the end of the coild leads and the rubber boot with WD40 before twisting them back on.
The reserve issue as mentioned by ChristoT is not a factor really with the fazer as it does not have a reserve tap, all fuel is taken from the same point low in the tank. Before draining the carbs change the Fuel filter and drain the tank. With fresh fuel in the tank drain the carbs and let the fuel run through for about 30 seconds closing the drain screw and opening it again after about 5 seconds during the 30 seconds on each carb. This helps wash any crap that may have stuck to the side of the float bowl during the initial draining.
