Just bought a 03 XB9s Lightning and after a few miles of riding it starts to bog at low RPM and steadily get worse. Got home and it was idling fine. Took it back out and it fell flat on its face in first and cleared up. It's getting worse and manly low rpm through all the gears. At first thought bad gas but now its got to be something else. I've delt with this before on cars but can't remember what it was and have never delt with it on bikes. Has anyone gone through this that can help pin point whats going on?
