FEATURES 1-2 EAS20170 FEATURES ET1D71017 OUTLINE OF THE FI SYSTEM The main function of a fuel supply system is to provide fuel to the combustion chamber at the optimum air-fuel ratio in accordance with the engine operating conditions and the atmospheric temperature. In the conventional carburetor system, the air-fuel ratio of the mixture that is supplied to the combustion chamber is created by the volume of the intake air and the fuel that is metered by the jet used in the respective carburetor. Despite the same volume of intake air, the fuel volume requirement varies by the engine operating conditions, such as acceleration, deceleration, or operating under a heavy load. Carburetors that meter the fuel through the use of jets have been provided with various auxiliary devices, so that an optimum air- fuel ratio can be achieved to accommodate the constant changes in the operating conditions of the engine. As the requirements for the engine to deliver more performance and cleaner exhaust gases increase, it becomes necessary to control the air-fuel ratio in a more precise and finely tuned manner. To accommodate this need, this model has adopted an electronically controlled fuel injection (FI) system, in place of the conventional carburetor system. This system can achieve an optimum air-fuel ratio required by the engine at all times by using a microprocessor that regulates the fuel injection volume according to the engine operating conditions detected by various sensors. The adoption of the FI system has resulted in a highly precise fuel supply, improved engine response, better fuel economy, and reduced exhaust emissions. 1 2 20 21 3 4 5678 9 10 11 12 14 13 16 19 18 17 16 15 1.

FEATURES 1-3 ET1D71018 FI SYSTEM The fuel pump delivers fuel to the fuel injector via the fuel filter. The pressure regulator maintains the fuel pressure that is applied to the fuel injector at only 392 kPa (3.92 kg/cm², 55.7 psi). Accordingly, when the energizing signal from the ECU energizes the fuel injector, the fuel passage opens, causing the fuel to be injected into the intake manifold only during the time the passage remains open. There- fore, the longer the length of time the fuel injector is energized (injection duration), the greater the volume of fuel that is supplied. Conversely, the shorter the length of time the fuel injector is energized (injection duration), the lesser the volume of fuel that is supplied. The injection duration and the injection timing are controlled by the ECU. Signals that are input from the throttle position sensor, crankshaft position sensor, intake air pressure sensor, air temperature sensor, engine temperature sensor, speed sensor and O 2 sensor enable the ECU to determine the injection duration. The injection timing is determined through the signals from the crankshaft position sensor. As a result, the volume of fuel that is required by the engine can be supplied at all times in accordance with the driving conditions.

FEATURES 1-4 ET1D71036 INSTRUMENT FUNCTIONS Multi-function meter unit WARNING EW1D71008 Be sure to stop the vehicle before making any setting changes to the multi-function meter unit. The multi-function meter unit is equipped with the following: • a speedometer (which shows the riding speed) • a tachometer (which shows the engine speed) • a fuel gauge • an odometer (which shows the total distance traveled) • two tripmeters (which show the distance traveled since they were last set to zero) • a fuel reserve tripmeter (which shows the distance traveled on the fuel reserve) • a clock • a self-diagnosis device • a brightness control mode NOTE: • Be sure to turn the key to “ON” before using the “SELECT” and “RESET” switches. • To switch the odometer, the tripmeters and the fuel reserve tripmeter displays between kilo- meters and miles, press the “SELECT” switch for at least two seconds. (For USA and Califor- nia only) Speedometer The speedometer shows the riding speed. When the key is turned to “ON”, the speedometer needle will sweep once across the speed range and then return to zero in order to test the electrical circuit. Tachometer The electric tachometer allows the rider to mon- itor the engine speed and keep it within the ideal power range. When the key is turned to “ON”, the tachometer needle will sweep once across the r/min range and then return to zero r/min in order to test the electrical circuit. 1. Speedometer 2. Fuel gauge 3.

FEATURES 1-5 CAUTION: EC1D71017 Do not operate the engine in the tachometer red zone. Red zone: 5000 r/min and above Fuel gauge The fuel gauge indicates the amount of fuel in the fuel tank. The needle moves towards “E” (Empty) as the fuel level decreases. When the needle reaches “E”, approximately 3.0 L (0.79 US gal) (0.66 Imp.gal) remain in the fuel tank. If this occurs, refuel as soon as possible. When the key is turned to “ON”, the fuel gauge needle will sweep once across the fuel level range and then return to the current amount in order to test the electrical circuit. NOTE: • Do not allow the fuel tank to empty itself com- pletely. • The fuel gauge does not indicate the correct fuel level for the first 5 km/h (3 mi/h) after refueling. Odometer, tripmeter, and clock modes Push the “SELECT” switch to switch the display between the odometer mode “ODO”, the tripmeter modes “TRIP 1” and “TRIP 2” and the clock mode in the following order: ODO → TRIP 1 → TRIP 2 → Clock → ODO If the fuel level warning light comes on, the odometer display will automatically change to the fuel reserve tripmeter mode “F-TRIP” and start counting the distance traveled from that point. In that case, push the “SELECT” switch to switch the display between the various tripmeter, odometer, and clock modes in the following order: F-TRIP → TRIP 1 → TRIP 2 → Clock → ODO → F-TRIP To reset a tripmeter, select it by pushing the “SE- LECT” switch, and then push the “RESET” switch for at least one second. If you do not reset the fuel reserve tripmeter manually, it will reset itself automatically, and the display will return to the prior mode after refueling and traveling 5 km (3 mi). Clock mode To set the clock: 1. Push the “SELECT” switch to change the display to the clock mode. 2. Push the “SELECT” and “RESET” switches together for at least two seconds. 3. When the hour digits start flashing, push the “RESET” switch to set the hours. 4. Push the “SELECT” switch, and the minute digits will start flashing. 5. Push the “RESET” switch to set the minutes. 6. Push the “SELECT” switch and then release it to start the clock. Self-diagnosis device This model is equipped with a self-diagnosis device for various electrical circuits. 1. Fuel gauge 1. Odometer/tripmeter/fuel reserve tripmeter/clock 1 1 1. Clock 1

FEATURES 1-6 If any of those circuits are defective, the engine trouble warning light will come on, and then the odometer/tripmeter/clock display will indicate a two-digit error code (e.g., 12, 13, 14). If the odometer/tripmeter/clock display indicates any error codes, note the code number, and then check the vehicle. Refer to “FUEL INJEC- TION SYSTEM” on page 7-27. CAUTION: EC1D71018 If the display indicates an error code, the vehicle should be checked as soon as possible in order to avoid engine damage. Brightness control mode The brightness can be adjusted for the following: • the multi-function meter unit panel (item number “1”) • the LCD (item number “2”) • the speedometer, tachometer, and the fuel gauge needles (item number “3”) Select the brightness control mode as follows. 1. Turn the key to “OFF”. 2. Push and hold the “SELECT” switch. 3. Turn the key to “ON”, and then release the “SELECT” switch after five seconds. Item number “1” is displayed. 4. Adjust the multi-function meter unit panel brightness level by pushing the “RESET” switch. 5. Push the “SELECT” switch to select the LCD. Item number “2” is displayed. Adjust the LCD brightness level by pushing the “RESET” switch. 6. Push the “SELECT” switch to select the speedometer, tachometer, and the fuel gauge needles. Item number “3” is displayed. Adjust the brightness level of the speedometer, tachometer, and the fuel gauge needles by pushing the “RESET” switch. 1. Multi-function meter unit panel 2. LCD 3. Speedometer needle 4.
