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 air­fuel 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.

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. There­fore, 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
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.

1. Speedometer
2. Fuel gauge
3. Odometer/tripmeter/fuel reserve tripmeter/clock
4. Tachometer
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, except for
setting the brightness control mode.
To switch the odometer, the tripmeters and the fuel reserve tripmeter displays between kilo­meters and miles, press the “SELECT” switch for at least two seconds. (For USA and Califor­nia only)

2. Tachometer red zone
The electric tachometer allows the rider to mon­itor 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.
EC1D71017
CAUTION:
Do not operate the engine in the tachometer red zone. Red zone: 5000 r/min and above
Fuel gauge
1
1. 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 com­pletely.
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

1. Odometer/tripmeter/fuel reserve tripmeter/clock
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).

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. 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 INJEC­TION SYSTEM on page 7-27.

GENERAL TIGHTENING TORQUE SPECIFICATIONS
This chart specifies tightening torques for stan­dard fasteners with a standard ISO thread pitch. Tightening torque specifications for special com­ponents or assemblies are provided for each chapter of this manual. To avoid warpage, tight­en multi-fastener assemblies in a crisscross pat­tern and progressive stages until the specified tightening torque is reached. Unless otherwise specified, tightening torque specifications re­quire clean, dry threads. Components should be at room temperature.

NOTE:
Air filter
This models air filter is equipped with a disposable oil-coated paper element, which must not be
cleaned with compressed air to avoid damaging it.
The air filter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
Hydraulic brake and clutch systems
After disassembling the brake or clutch master cylinders, caliper cylinders or clutch release cylinder,
always change the fluid. Regularly check the brake and clutch fluid levels and fill the reservoirs as required.
Replace the oil seals on the inner parts of the brake or clutch master cylinders, caliper cylinders and clutch release cylinder every two years.
Replace the brake and clutch hoses every four years or if cracked or damaged.

ADJUSTING THE VALVE CLEARANCE
The following procedure applies to all of the valves.
NOTE:
The valve clearance is automatically adjusted by the hydraulic valve lifter. However, there are times when the valve clearance needs to be adjusted manually. If this is the case, adjust the clearance of the two maladjusted or worn valves using the adjusting screw on the rocker arm. If clearance is on the slip side “1”, loosen the adjusting screw and bring the valve clearance a within specification. Check if the valve clearance “b” on the adjusting screw “2” side is within specification.

If clearance is on the adjusting screw “2” side, tighten the adjusting screw and bring the valve clearance “b” within specification.
Valve clearance adjustment should be made on a cold engine, at room temperature.
When the valve clearance is to be measured or adjusted, the piston must be at top dead center (TDC) on the compression stroke.

ADJUSTING THE THROTTLE CABLE FREE PLAY
NOTE:
Prior to adjusting the throttle cable free play, the engine idling speed and throttle body synchroni­zation should be adjusted properly.
NOTE:
After each step, rev the engine two or three times, each time for less than a second, and check the synchronization again.
If the air screw was removed, turn the screw 3/4 turn in and be sure to synchronize the throt­tle body.
