I just bought a 1997 Bandit 1200. It seems to be idling way to fast. I tried to adjust the idle with the gold idle speed adjustment knob under the center cards. But I can turn the screw all day long until it falls out and the engine will still be idling at 2200 rpm. I checked the choke to make sure it was all the way off(open), which it was. Could the problem be with the throttle cables or may be the carb linkage. HELP.
