Due to friction plate wear and clutch cable stretch over a long period of use, the clutch operation should be checked each day before riding the motorcycle, and must be adjusted in accordance with the Periodic Maintenance Chart.
Inspection

A. Adjuster
B. Clutch Lever Play
Clutch Lever Play

If the play is incorrect, adjust the lever play as follows.
Adjustment
| WARNING Excess clutch cable play could prevent clutch disengagement and cause a crash resulting in serious injury or death. When adjusting the clutch cable, be sure the upper end of the outer cable is fully seated in its fitting so that it doesn’t slip into place later and create excessive cable play. |
| WARNING The engine and exhaust system get extremely hot during normal operation and can cause serious burns. Never touch a hot engine or an exhaust pipe during clutch adjustment. |
NOTE
DANGER
Exhaust gas contains carbon monoxide, a colorless, odorless poisonous gas. Inhaling carbon monoxide can cause serious brain injury or death.
DO NOT run the engine in enclosed areas. Operate only in a well-ventilated area.
