I have the same problem!!! I have a 2002 919 (original owner) this is a bike that I have never abused (when I parked it for the last time it was running fine with 2300 miles on it). I also let it sit for 1 1/2 years with gas in the tank (I know, I know). I tried to start it and the fuel pump was dead. I replaced the entire fuel pump assembly (this includes the fuel filter), the spark plugs, air filter, and battery. It started right up (yay!!!) then after running for a minute or less it became very rough (I had to throttle it to keep it from stalling). I noticed a fine mist coming out of the tail pipes and to my surprise it was gas. I have added gas with FI cleaner and ran it, but it goes through gas very fast as you can imagine. I tested the coils and all the plugs and they are fine, and now I am at a loss. I was hoping you could tell me if you ever found out what was wrong with your bike? Thanks!
