PERIODIC MAINTENANCE AND ADJUSTMENT EAU21992 EAU22073 Cast wheels To maximize the performance, durability, and safe operation of your vehicle, note the following points regarding the specified wheels. G The wheel rims should be checked for cracks, bends, warpage or damage before each ride. If any damage is found, have a Yamaha dealer replace the wheel. Do not attempt even the smallest repair to the wheel. A deformed or cracked wheel must be replaced. G The wheel should be balanced whenever either the tire or wheel has been changed or replaced. An unbalanced wheel can result in poor performance, adverse handling characteristics, and a shortened tire life. G Ride at moderate speeds after changing a tire since the tire surface must first be "broken in" for it to develop its optimal characteristics. G After repairing or replacing the rear tire, tighten the valve stem nut and locknut to the specified torques. Clutch lever 1 2 1. Valve stem nut 2. Valve stem locknut 1. Clutch lever free play Tightening torques: Valve stem nut: 1.6 Nm (0.16 m·kgf, 1.16 ft·lbf) Valve stem locknut: 1.6 Nm (0.16 m·kgf, 1.16 ft·lbf) 8 Since this model is equipped with a hydraulic clutch, adjusting the clutch lever free play is not needed. However, it is necessary to check the clutch fluid level and check the hydraulic system for leakage before each ride. (See page 8-25.) If the clutch lever free play does become excessive, and shifting becomes rough or clutch slippage occurs, causing poor acceleration, there may be air in the clutch system. If there is air in the hydraulic system, have a Yamaha dealer bleed the system before operating the motorcycle. 8-23
