Check that all steering open and close positions are smooth.
Wire Inspection:
Check that the throttle grip rotation is smooth from the fully open position to the fully closed position. Check when the steering is fully to the left and to the right. Check the condition of the throttle cable to the carburetor. If the cable is cracked, cut, or improperly routed, it must be replaced or re-routed. The slack of the throttle handle (1) is approximately 2-6mm of grip rotation.
