HELP!2004 GS500F riding along fine, suddenly bike lost power like it was going to reserve tank. Flipped petcock to reserve, no help. 60 MPH top speed in 4th gear! But, pull the clutch in, revs to the redline, and idles. Pop it back in gear and no power A good analogy is it feels lke your driving a car with the emergency brake on. Pulled the plugs, and they are good and the plugs have less then 5,000 miles on them. Bike is a daily driver with 26,000+ miles and is routinely maintained. Has me stumped..
