EAU00021 1 Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power and freedom. However, they also impose certain limits, which you must accept; even the best motorcycle does not ignore the laws of physics. Regular care and maintenance are essential for preserving value and operating condition of your motorcycle. Moreover, what is true for the motorcycle is also true for the rider: good performance depends on being in good shape. Riding under the influence of medication, drugs and alcohol is, of course, out of the question. Motorcycle riders--more than car drivers--must always be at their mental and physical best. Under the influence of even small amounts of alcohol, there is a tendency to take dangerous risks. Protective clothing is as essential for the motorcycle rider as seat belts are for car drivers and passengers. Always wear a complete motorcycle suit (whether made of leather or tear-resistant synthetic materials with protectors), sturdy boots, motorcycle gloves and a properly fitting helmet. Optimum protective wear, however, should not encourage carelessness. Although full-coverage helmets and suits, in particular, create an illusion of total safety and protection, motorcyclists will always be vulnerable. Riders who lack critical self-control run the risk of going too fast and are apt to take chances. This is even more dangerous in wet weather. The good motorcyclist rides safely, predictably and defensively--avoiding all dangers, including those caused by others. Enjoy your ride! 1-1 EAU00026 DESCRIPTION Left view 1 2 23 4 5 6 10 98 7 1. 2. 3. 4. 5.

Therefore, handle the YEIS air chamber and air chamber hose with special care and immediately replace any cracked or damaged parts. YPVS This model is equipped with the YPVS (Yamaha Power Valve System). This system boosts engine performance and efficiency by means of a variable valve in the exhaust port. The YPVS valve is constantly adjusted in accordance with the engine speed by a computer-controlled servomotor. Since the YPVS is an important part of the engine and requires very sophisticated adjustment, have a Yamaha dealer, who has the necessary professional knowledge and experience, make this adjustment. 8 Do not exceed the load limit of 2 kg for the carrier. 8 Do not exceed the maximum load of 180 kg/178 kg (for CH, A) for the vehicle. cC EC000022 Do not attempt to modify the YEIS in any way. 3-14 INSTRUMENT AND CONTROL FUNCTIONS cC EC000023 EAU00330 Sidestand The sidestand is located on the left side of the frame. Raise the sidestand or lower it with your foot while holding the motorcycle upright. NOTE: The built-in sidestand switch is part of the ignition circuit cut-off system, which cuts the ignition in certain situations. (See further down for an explanation of the ignition circuit cutoff system.) w EW000044 The YPVS has been set and extensively tested at the Yamaha factory. Changing these settings without sufficient technical knowledge may result in poor performance of or damage to the engine. YPVS operation noises can be heard in the following instances: 8 When the key is turned to "ON" and the engine is started. 8 When the engine stalls with the key in the "ON" position. cC EC000024 If the YPVS does not operate, have a Yamaha dealer check it. The motorcycle must not be ridden with the sidestand down, or if the sidestand cannot be properly moved up (or does not stay up), otherwise the sidestand could contact the ground and distract the operator, resulting in a possible loss of control. Yamaha's ignition circuit cut-off system has been designed to assist the operator in fulfilling the responsibility of raising the sidestand before starting off. Therefore, check this system regularly as described below and have a Yamaha dealer repair it if it does not function properly. 3 3-15 INSTRUMENT AND CONTROL FUNCTIONS EAU03571 Ignition circuit cut-off system The ignition circuit cut-off system (comprising the sidestand switch and neutral switch) has the following functions. 8 It prevents starting when the transmission is in gear and the sidestand is still down. 8 It cuts the running engine when the transmission is in gear and the sidestand is moved down.

Turn the fuel cock lever to "ON". 2. Turn the key to "ON" and make sure that the engine stop switch is set to "#". 3. Shift the transmission into the neutral position. NOTE: When the transmission is in the neutral position, the neutral indicator light should be on, otherwise have a Yamaha dealer check the electrical circuit. 5 5-1 OPERATION AND IMPORTANT RIDING POINTS 4. Turn the starter (choke) on and completely close the throttle. (See page 3-10 for starter (choke) operation.) 5. Start the engine by pushing the kickstarter lever down. 6. After starting the engine, move the starter (choke) lever back halfway. EAU01258 Starting a warm engine Follow the same procedure as for starting a cold engine with the exception that the starter (choke) is not required when the engine is warm. 6 5 4 3 2 N 1 1 cC 5 ECA00045 1. Shift pedal N. Neutral position EAU00423 For maximum engine life, never accelerate hard when the engine is cold! 7. When the engine is warm, turn the starter (choke) off. NOTE: The engine is warm when it responds normally to the throttle with the starter (choke) turned off. Shifting Shifting gears lets you control the amount of engine power available for starting off, accelerating, climbing hills, etc. The gear positions are shown in the illustration. NOTE: To shift the transmission into the neutral position, press the shift pedal down repeatedly until it reaches the end of its travel, and then slightly raise it. 5-2 OPERATION AND IMPORTANT RIDING POINTS cC EC000048 EAU02937 EAU00424 8 Even with the transmission in the neutral position, do not coast for long periods of time with the engine off, and do not tow the motorcycle for long distances. The transmission is properly lubricated only when the engine is running. Inadequate lubrication may damage the transmission. 8 Always use the clutch while changing gears to avoid damaging the engine, transmission, and drive train, which are not designed to withstand the shock of forced shifting. Recommended shift points (for Switzerland only) The recommended shift points during acceleration are shown in the table below. Shift point (km/h) Tips for reducing fuel consumption Fuel consumption depends largely on your riding style. Consider the following tips to reduce fuel consumption: 8 Thoroughly warm up the engine. 8 Turn the starter (choke) off as soon as possible. 8 Shift up swiftly, and avoid high engine speeds during acceleration. 8 Do not rev the engine while shifting down, and avoid high engine speeds with no load on the engine. 8 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). 1st 2nd 3rd 4th 5th 2nd 3rd 4th 5th 6th 20 30 40 50 60 5 NOTE: When shifting down two gears at a time, reduce the speed accordingly (e.g., down to 35 km/h when shifting from 5th to 3rd gear). 5-3 OPERATION AND IMPORTANT RIDING POINTS EAU00436 EAU00453 Engine break-in There is never a more important period in the life of your engine than the period between 0 and 1,000 km. 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 1,000 km. 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. 0­500 km 8 Avoid prolonged operation above 6,000 r/min. 8 After every hour of operation, stop the engine, and then let it cool for five to ten minutes. 8 Vary the engine speed from time to time. Do not operate the engine at one set throttle position. 500­1,000 km 8 Avoid prolonged operation above 7,000 r/min. 8 Rev the engine freely through the gears, but do not use full throttle at any time. 1,000 km and beyond The vehicle can now be operated normally. cC EC000053 5 8 Keep the engine speed out of the tachometer red zone. 8 If any engine trouble should occur during the engine breakin period, immediately have a Yamaha dealer check the vehicle. cC EC000060 After 1,000 km of operation, the transmission oil must be changed. 5-4 OPERATION AND IMPORTANT RIDING POINTS EAU00458 Parking When parking, stop the engine, remove the key from the main switch, and then turn the fuel cock lever to "OFF". w
