Hey, I´ve got an 05 GS500F and my bike started lurching on my way to work in 6th gear and it went to idle at 500rps and then died. It took some effort to get it running again, and it runs fine up to 4th gear. Does the same, lurches, idle, died. Help anyone? Tech suggested cleaning the fuel filter and fuel lines, and another woman had the same problem and just charged the battery. I´m stumped...help?
