Well my buddy has an 00 zx6 and its got some sort of problem. It starts and idles fine until it warms up, and then you have to keep giving it throttle to get it to stay running. If not, then it dies out. We've cleaned the carbs, changed plugs, etc and to no avail. So what else could it be. another one of our friends said that the motor was getting ready to let go and it needs rebuilt but that doesnt sound right. So any suggestions on what to try?
