I was running the bike at idle after about 2 weeks of it sitting and it died. When I started it again it ran very rough and continues to die after about 30 seconds of struggling. When I give it gas it gets worse. The fuel pump and filter are almost new. The injectors were rebuilt in 18 and the plugs are relatively new too. It seems like an issue with gas but I'm not really sure where to start. Can anyone point me in the direction of where to start?

Hi ,you don't say if fast idle (choke) is used or not. So with choke full on start engine allow to run stop without opening throttle, when engine stops remove plugs, Black and wet, Over fuelling Clean and dry under fuelling. AND check for plugs sparking.

What has the weather done lately?  Any big temperature changes, wet weather, dampness?  It's not that unusual to have condensation in the tank that gets into the fuel this time of year.  Since I have no idea where Bluffton is, I can't say if there is a chance that is contributing to your problem, but you might want to think about throwing some drygas in the tank and spraying some WD40 on the wiring.

I'm in South Carolina. I didn't even think about moisture issues. Thanks
