Maintenance of Usr 125 Throttle Pipeline

1. Adjust the throttle handle: start the engine, adjust the clearance and tightness of the throttle handle, and speed up the test run. If you feel that the throttle handle is heavy, it means that the throttle cable is interfering.

2. Adjust the cable clearance: completely restore the throttle handle to the normal state, hold the adjusting nut, and pull the digging wire outward for 2 ~ 3mm to see if the clearance is appropriate. If the gap is too big, it should be readjusted.

3. Adjust the lock nut: completely restore the throttle handle to the normal state, rotate the nut forward and backward, and drive the cable to move up and down, so that the clearance of 1 to 2mm is fixed with the lock nut.
