OPERATION AND IMPORTANT RIDING POINTS EUU73802 EAF30000 1. 2. 3. 4. 5. WARNING Avoid hard or sudden braking. It may cause the scooter to skid or overturn. Be sure to apply the brake carefully if leaning over to one side. Improper braking could lead to a skid. Street car rails, metal plates on road construction sites, and manhole covers become particularly slippery when they get wet. Cross them slowly and cautiously. Braking on a wet road will be very difficult. Braking on a hill can be difficult. Proceed slowly when riding downhill. Engine break-in There is never a more important period in the life of your scooter than the period between zero and 1,000 km (600 mi). For this reason we ask that you carefully read the following material. Because the engine is brand new, you must not put an excessive load on it for the first 1,000 km (600 mi). The various parts in the engine wear and polish themselves to the correct operating clearances. During this period, prolonged full throttle operation, or any condition which might result in excessive heating of the engine, must be avoided. 2. 150 ~ 500 km (90 ~ 300 mi): Avoid prolonged operation above 1/2 throttle. EUU35300 CAUTION: After 1,000 km (600 mi) of operation, be sure to replace the transmission oil. 3. 500 ~ 1,000 km (300 ~ 600 mi): Avoid cruising speeds in excess of 3/4 throttle. 4. 1,000 km (600 mi) and beyond: Avoid prolonged full throttle operation. Vary speeds occasionally. EUU32200 6 EAF32000 1. 0 ~ 150 km (0 ~ 90 mi): Avoid operation above 1/3 throttle. Stop the engine and let it cool for 5 to 10 minutes after every hour of operation. Vary the speed of the scooter from time to time. Do not operate it at one set throttle position. 6-4 CAUTION: If any engine trouble should occur during the break-in period, consult a Yamaha dealer immediately.
