Alright, my 2004 America, with just over 2000 miles just started running like crap. Rode the bike to my destination, left 3 hours later. Bike started fine, ran fine for a couple blocks, and then it started to backfire, and shut off leaving a stop light. Bike starts right up, but idles rough. Give it some gas it starts popping and back firing. Try to rev it up, to clear it out, it will rev roughly and then back fire and shut off. Pulled the plugs they look good. Haven't had a chance to look into other things. Just thought before I do, I'd see if anyone has had similar problems, and what did they do to fix it. Thanks for looking.
