I have a 2004 FI fatboy that I recently changed handlebars on. I had to take the tank off to run the wires throught the bars. I put the tank back on and the bike starts and idles fine but when I give it some throttle it starts to spit and sputter then eventually will die if I dont let off the throttle. Any ideas what the problem could be? Also, even though it has a 1/2 tank of gas for some reason the gas light will not go off. Thanks for any help.
