Engine break-in OPERATION AND IMPORTANT RIDING POINTS EAU16820 EAU16830 EAU15943 Tips for reducing fuel consumption 1 2 3 4 5 6 7 8 9 Fuel consumption depends largely on your riding style. Consider the following tips to reduce fuel consumption: ● Avoid high engine speeds during acceleration. ● Avoid high engine speeds with no load on the engine. ● Turn the engine off instead of letting it idle for an extended length of time (e.g., in traffic jams, at traffic lights or at railroad crossings). Engine break-in There is never a more important period in the life of your engine than the period between 0 and 1000 km (600 mi). For this reason, you should read the following material carefully. Since the engine is brand new, do not put an excessive load on it for the first 1000 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 that might result in engine overheating must be avoided. EAU16951 150 ~ 500 km (90 ~ 300 mi) Avoid prolonged operation above 1/2 throttle. Rev the engine freely through the gears, but do not use full throttle at any time. 500 ~ 1000 km (300 ~ 600 mi) Avoid prolonged operation above 3/4 throttle. NOTICE: After 1000 km (600 mi) of operation, the engine oil must be changed and the oil strainer cleaned.[ECA10351] 1000 km (600 mi) and beyond Avoid prolonged full-throttle operation. Vary the speed occasionally. ECA10270 0 ~ 150 km (0 ~ 90 mi) Avoid prolonged operation above 1/3 throttle. After every hour of operation, stop the engine, and then let it cool for five to ten minutes. Vary the engine speed from time to time. Do not operate the engine at one set throttle position. NOTICE If any engine trouble should occur during the engine break-in period, immediately have a Yamaha dealer check the vehicle. 5-36 5-3
