PERIODIC MAINTENANCE AND MINOR REPAIR EWA10460 EWA10600 EAU21980 WARNING G WARNING This motorcycle is fitted with superhigh-speed tires. Note the following points in order to make the most efficient use of these tires. G Use only the specified replacement tires. Other tires may run the danger of bursting at super high speeds. G Brand-new tires can have a relatively poor grip on certain road surfaces until they have been "broken in". Therefore, it is advisable before doing any highspeed riding to ride conservatively for approximately 100 km (60 mi) after installing a new tire. G The tires must be warmed up before a high-speed run. G Always adjust the tire air pressure according to the operating conditions. Cast wheels To maximize the performance, durability, and safe operation of your motorcycle, 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 a tire, tighten the valve stem nut and locknut to the specified torques. G The front and rear tires should be of the same make and design, otherwise the handling characteristics of the vehicle cannot be guaranteed.
