I was riding my bike down to the shops just now. It was coughing in first then the engine cut out when I opened the throttle. Yep, checked the tank, I have fuel. I tried rolling start but it fires and just doesn't continue to fire. Hitting the starter with a fresh battery from my other bike doesn't help, it fires, but won't start. I was thinking "Hmm ok perhaps this has a reserve tank and the fuel is low, despite the fuel warning light not being on". I've read conflicting posts on this, people are saying the CBR600F4 does/does not have a reserve tank and one forum claimed it doesn't have a petcock but I know it does because of a parts diagram, I just can't locate it. Has anyone got some handy suggestions?
