I have a 2002 Vulcan Classic FI. I washed it Saturday night and since then, it hasn't run right. It spits, sputters, backfires, and shoots flames. When I accelerate, it barely moves. Or if I start out running ok, all of a sudden it almost dies. My fuel injection light came on for about 10 seconds and then went off. I checked the spark plugs (which seemed ok) and everything else that I can think of. Any suggestions?
