EAS20090 HOW TO USE THIS MANUAL This manual is intended as a handy, easy-to-read reference book for the mechanic. Comprehensive explanations of all installation, removal, disassembly, assembly, repair and check procedures are laid out with the individual steps in sequential order. • The manual is divided into chapters and each chapter is divided into sections. The current section title is shown at the top of each page “1”. • Sub-section titles “2” appear in smaller print than the section title. • To help identify parts and clarify procedure steps, there are exploded diagrams “3” at the start of each removal and disassembly section. • Numbers “4” are given in the order of the jobs in the exploded diagram. A number indicates a disassembly step. • Symbols “5” indicate parts to be lubricated or replaced. Refer to “SYMBOLS”. • A job instruction chart “6” accompanies the exploded diagram, providing the order of jobs, names of parts, notes in jobs, etc. • Jobs “7” requiring more information (such as special tools and technical data) are described sequen- tially.

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.
