FEATURES EAS20170 FEATURES EAS4B51038 OUTLINE OF 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. In a 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 chamber.
Page 12: Fi System
FEATURES EAS4B51039 FI SYSTEM The fuel pump delivers fuel to the fuel injector via the fuel filter. The pressure regulator (in the fuel pump) maintains the fuel pressure that is applied to the fuel injector at 245–255 kPa (2.45–2.55 kgf/ , 35.5–37.0 psi) higher than the intake manifold pressure.

Page 14 FEATURES Odometer and tripmeter modes system. If a problem is detected in the electrical circuit, the following cycle is repeated until the malfunction is corrected: fuel level segments and symbol “ ” flash eight times, then go off for approximately 3 seconds. If this occurs, check the electrical circuit.
Page 15 FEATURES 1. Use the code re-registering key to start the engine. Make sure there are no other immobilizer keys close to the main switch, and do not keep more than one immobilizer key on the same key ring! Immobilizer system keys may cause signal inter- ference, which may prevent the engine from starting.
Page 16: Outline Of The Abs
4. Rear wheel sensor The operation of the Yamaha ABS brakes is the same as conventional brakes on other vehicles, with a front brake lever for operating the front brake and a rear brake pedal for operating the rear brake.
Page 17 FEATURES Side force: The force on the tires which supports the vehicle when cornering. Slip ratio: When the brakes are applied, slipping occurs between the tires and the road surface. This causes a difference between the wheel speed and the chassis speed. Slip ratio is the value that shows the rate of wheel slippage and is defined by the following formula.
Page 18 FEATURES The difference between the chassis speed and the wheel speed calculated in the slip ratio formula is equal to the wheel slip. When the wheel speed is suddenly reduced, the wheel has a tendency to lock. When the wheel slip and the wheel speed reduction rate exceed the preset values, the ABS ECU de- termines that the wheel has a tendency to lock.
Page 19 Slip ratio (%) b. Brake force Electronic ABS features The Yamaha ABS (anti-lock brake system) has been developed with the most advanced electronic technology. The ABS control is processed with good response under various vehicle travel conditions. The ABS also includes a highly developed self-diagnosis function. The ABS detects any problem con- dition and allows normal braking even if the ABS is not operating properly.

Wheel sensor ABS warning light The ABS warning light “1” comes on to warn the rider if a malfunction in the ABS occurs. When the main switch is turned to “ON”, the ABS warning light comes on for 2 seconds, then goes off, so that the rider can check if the ABS warning light is disconnected and check if the ABS is operating properly.
Page 22 FEATURES Hydraulic control valve The hydraulic control valve is composed of a inlet solenoid valve and outlet solenoid valve. The electromagnetic force generated in the inlet solenoid valve varies proportionally with the duty cycle control voltage that is supplied to it. Since this voltage is continuously variable, the solenoid valve moves smoothly and the hydraulic pressure is adjusted linearly.
Page 23 FEATURES Buffer chamber The buffer chamber accumulates the brake fluid that is depressurized while the ABS is operating. 1. Buffer chamber (pressurizing phase) 2. Buffer chamber (depressurizing phase) 3. Raised piston 1-14...
Page 24 FEATURES ABS ECU The ABS ECU is integrated with the hydraulic unit to achieve a compact and lightweight design. As shown in the block following diagram, the ABS ECU receives wheel sensor signals from the front and rear wheels and also receives signals from other monitor circuits. 16 17 18 19 17.
Page 25: Abs Operation
FEATURES Some types of malfunctions are not recorded in the memory of the ABS ECU (e.g., a blown ABS ECU fuse). The ABS performs a self-diagnosis test for a few seconds each time the vehicle first starts off after the main switch was turned on. During this test, a “clicking” noise can be heard from under the seat and if the front brake lever or rear brake pedal are even slightly applied, a vibration can be felt at the lever or pedal, but these do not indicate a malfunction.
Page 26 FEATURES Normal braking (ABS not activated) When the ABS is not activated, the inlet solenoid valve is open and the outlet solenoid valve is closed because a control signal has not been transmitted from the ABS ECU. Therefore, when the brake lever is squeezed, the hydraulic pressure in the brake master cylinder increases and the brake fluid is sent to the brake caliper.
Page 27 FEATURES Emergency braking (ABS activated) 1. Depressurizing phase When the front wheel is about to lock, the outlet solenoid valve is opened by the “depressurization” signal transmitted from the ABS ECU. When this occurs, the inlet solenoid valve compresses the spring and closes the brake line from the brake master cylinder.

Page 31: Abs Warning Light And Operation
FEATURES EAS4B56012 ABS WARNING LIGHT AND OPERATION ABS warning light When the main switch is turned to “ON”, the ABS warning light comes on for 2 seconds, then goes off. The ABS warning light comes on while the start switch is being pushed. If the ABS warning light comes on while riding, stop the vehicle, and then turn the main switch to “OFF”, then back to “ON”.
Page 32 FEATURES and tires is close to the limit. The ABS cannot prevent wheel lock* on slippery surfaces, such as ice, when it is caused by engine braking, even if the ABS is activated. The ABS is not designed to shorten the braking distance or improve the cornering perfor- mance.
Page 33: Important Information
5. Keep all parts away from any source of fire. EAS20200 REPLACEMENT PARTS Use only genuine Yamaha parts for all replace- ments. Use oil and grease recommended by Yamaha for all lubrication jobs. Other brands may be similar in function and appearance, but inferior in quality.
Page 34: Bearings And Oil Seals
IMPORTANT INFORMATION EAS20230 BEARINGS AND OIL SEALS Install bearings “1” and oil seals “2” so that the manufacturer’s marks or numbers are visible. When installing oil seals, lubricate the oil seal lips with a light coat of lithium-soap-based grease. Oil bearings liberally when installing, if appropriate.

Page 416: Ecu Self-Diagnostic Function
FUEL INJECTION SYSTEM EAS27350 ECU SELF-DIAGNOSTIC FUNCTION The ECU is equipped with a self-diagnostic function in order to ensure that the fuel injection system is operating normally. If this function detects a malfunction in the system, it immediately operates the en- gine under substitute characteristics and illuminates the engine trouble warning light to alert the rider that a malfunction has occurred in the system.
Page 417 FUEL INJECTION SYSTEM The ECU takes fail-safe actions in two ways: one in which the sensor output is set to a prescribed value, and the other in which the ECU directly operates an actuator. Details on the fail-safe actions are given in the table below.
