1 - 1 GEN INFO EAS00014 GENERAL INFORMATION MOTORCYCLE IDENTIFICATION EAS00017 VEHICLE IDENTIFICATION NUMBER The vehicle identification number 1 is stamped into the right side of the steering head pipe. EAS00018 MODEL LABEL The model label 1 is affixed to the frame.
1 - 2 GEN INFO FEATURES FEATURES OUTLINE OF FI SYSTEM The main function of a fuel supply system is to provide fue l to the combustion chamber at the opti- mum air-fuel ratio in accordance with the en gine operating conditions and the atmospheric tempera- ture.
1 - 3 GEN INFO FEATURES FI SYSTEM The fuel pump delivers fuel to the inje ctor via the fuel filter. The pressure regulator mainta ins the fuel pressure that is applied to the injector at only 284 kPa (2.84 kg/cm 2 , 40.4 psi) higher than the intake manifold pressure.
1 - 4 GEN INFO FEATURES Fuel control block The fuel control block consists of the fo llowing main components: An engine trouble warning light is provided on meter p anel.
1 - 5 GEN INFO FEATURES COMPONENTS ECU (Electronic Control Unit) The ECU is mounted underneath the seat. The main fun ctions of the ECU are ignitio n control, fuel control, self-diagnosis, and lo ad control.
1 - 6 GEN INFO FEATURES • Ignition control The ignition control function of th e ECU controls the ignition timing and the duration of ignition energizing.
1 - 7 GEN INFO FEATURES Fuel pump The fuel pump, which is mounted in the fuel tank, draws the fuel directly from the tank and pumps it to the injector. A filter that is provided in the fuel pump prevents any debris in the fuel tank from entering the fu el system downstream of the pump.
1 - 8 GEN INFO FEATURES Pressure regulator It regulates the fuel pressure that is applied to the in jectors that are provided in th e cylinders in order to maintain a constant pressure d ifference with the pressure in the intake manifold.
1 - 9 GEN INFO FEATURES Fuel injector Upon receiving injection signals from the ECU, the fuel injector injects fuel. In the normal state, the core is pressed downward by t he force of the spring, as illustrated. The plunger tha t is integrated with the bottom of the core keeps the fuel pa ssage closed.
1 - 10 GEN INFO FEATURES Crankshaft position sensor The crankshaft position sensor uses the signals of the pickup co il that is mounted on the right side of the crankshaft.
1 - 11 GEN INFO FEATURES Cylinder identification sensor The cylinder identification sensor is mounted on the middle of exhaust side head cover. When the exhaust camshaft rotates, the sensor generates a signal and sends it to the ECU.
1 - 12 GEN INFO FEATURES Throttle position sensor The throttle position sensor measures the intake air volume by detectin g the position of the throt tle valve. It detects th e mechanical angle of the throttle valve through the posit ional relationship between the moving contact that moves in unison with the throttle shaft and the resistor boa rd.
1 - 13 GEN INFO FEATURES Intake air pressure sensor and atmos pheric pressure sensor • Intake air pressure se nsor The intake air pressure sensor is used for measuring the intake air volume. The intake air volume of every intake stroke is proportionate to th e intake air pressure.
1 - 14 GEN INFO FEATURES Coolant temperature sensor The signals from the coolant tempe rature sensor are used primarily for making fuel volume compen- sations during starting and warm-up. The coolan t temperature sensor converts the temperature of the coolant into electrical signals and sends them to the ECU.
1 - 15 GEN INFO FEATURES Lean angle cut-off switch The lean angle cut-off switch stops the supply of fuel to the engine in case the motorcycle overturns. When the motorcycle is in the normal state, the cut-off switch outputs a constant voltage of approxi- mately 1.
1 - 16 GEN INFO FEATURES FUEL INJECTION SYSTEM Operation and control The fuel injection timing, injection duration, ignitio n timing, and the coil energizing duration are con- trolled by the ECU.
1 - 17 GEN INFO FEATURES Determining the final injection duration The intake air volume determines the basic injection duration. Ho wever, at a given intake air vol- ume, the volume of fuel that is required varies by th e engine operating conditions such a s accelera- tion or deceleration, or by weather conditions.
1 - 18 GEN INFO FEATURES Reactive injection duration: A lag is created between the time the ECU outputs a fuel injection signal to the injector and the time the injector actually opens. Therefore, the ECU ca lculates this lag in advance before se nding the actuation signal to the injector.
1 - 19 GEN INFO FEATURES THREE-WAY CATALYTIC CONVERTER SYSTEM System outline This is a highly efficient exhaust gas cleaning system that effects air-fuel cont rol through a joint effort by the FI system and the three-way cata lytic converter system.
1 - 20 GEN INFO FEATURES INSTRUMENT FUNCTION Multi-function display The multi-function display is equipped with the following: • a speedometer (which shows the riding speed) • an odometer (which s.
1 - 21 GEN INFO FEATURES Display brightness and engine speed indi- cator light control mode This mode cycles through five control func- tions, allowing you to make the following set- tings in the order listed below.
