This was my first ride of the season. Before heading for work I filled the tank with Super Premium gas. On the way to work the bike started to sputter. The RPM gauge was bouncing all over the place. After work I went to start it, the lights came on and everything, but when I pushed the button to start it everything turned off. I turned the key off and tried again, same thing. I finally got it started and went home. I also notice that when the bike is in neutral that the green neutral light is either very dim or if flickers. What could be the problem? Is it my carbs, fuel filter, air filter, spark plugs, battery?
