  FEATURES EAS20170 FEATURES ET2C01025 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.

• Page 12: Fi System

  FEATURES ET3P61042 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 324 kPa (3.24 kg/cm², 46.1 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.

• Page 13: Outline Of The Unified Brake System

  OUTLINE OF THE UNIFIED BRAKE SYSTEM The Yamaha unified brake system is a system that operates one set of pistons in the front brakes to- gether with the rear brake when the brake pedal is depressed. Compared to conventional brake sys- tems, the ability to slow the vehicle using the simple operation of the brake pedal is improved.

• Page 14: Outline Of The Abs

  ET3P61019 OUTLINE OF THE ABS 1. The Yamaha ABS (anti-lock brake system) features an electronic control system, which acts on the front and rear brakes independently. However, one set of pistons in the right front brake caliper is operated together with the rear brake and this set of pistons is operated only if the force used to de- press the brake pedal exceeds a preset level.

• Page 15
  9. Rear wheel sensor rotor The operation of the Yamaha ABS brakes is the same as conventional brakes on other vehicles, with a brake lever for operating the front brake and a brake pedal for operating the rear brake. However, part of the front brake is operated together with rear brake.
• Page 16
  FEATURES • 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. Chassis speed –…
• Page 17
  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 18
  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.

  FEATURES 3. At high speed 6. Wheel sensor 4. At low speed 5. Wheel sensor rotor 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 21
  FEATURES When the ABS is activated, the flow control valve regulates the flow of brake fluid to the brake and the solenoid valve decreases and increases the brake fluid pressure. 1. When the brakes are operated normally, the solenoid valve “2” is closed, the spool “3” of the flow control valve does not move, and the hydraulic line between the brake master cylinder and brake caliper is open.

  FEATURES 1. Buffer chamber (pressurized) 3. Raised piston 2. Buffer chamber (depressurized) ABS ECU (electronic control unit) The ABS ECU “1” controls the ABS and is installed under the storage compartment. To protect the ABS ECU from water damage, it is protected by a cover “2”. 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.

  FEATURES Normal braking (ABS not activated) When the ABS is not activated, port D “11” of the solenoid valve is closed because a control signal has not been transmitted from the ABS ECU and port A “7” and port B “9” of the flow control valve are open. Therefore, when the brake lever is squeezed, the hydraulic pressure in the brake master cylinder in- creases and the brake fluid is sent to the brake caliper via port A and port B.
• Page 27
  FEATURES Emergency braking (ABS activated) 1. Depressurized state When the front wheel is about to lock, port D “11” of the solenoid valve is opened by the “depressur- ization” signal transmitted from the ABS ECU. When this occurs, the spool of the flow control valve compresses the return spring and closes port B “9”.
• Page 28
  FEATURES 2. Pressurized state Port D “11” is closed by the “pressurization” signal transmitted from the ABS ECU. Before this oc- curs, the spool of the flow control valve has compressed the return spring and closed port B “9”. Brake fluid that has entered through port A “7” is further restricted by the orifice “10” and the brake fluid is sent to the brake caliper via port A “7”…

  FEATURES ET3P61053 ABS SELF-DIAGNOSIS FUNCTION ABS warning light The ABS warning light “1” comes on when a malfunction is detected by the ABS self-diagnosis. It is located in the meter assembly. Instances when the ABS warning light comes on 1. The ABS warning light comes on when the main switch is turned to “ON”. The ABS warning light comes on for 2 seconds while the ABS is performing a self-diagnosis, then goes off if there are no problems.

• Page 30
  FEATURES 3. The ABS warning light comes on while riding. If the ABS warning light comes on while riding, a malfunction has been detected in the ABS. The ABS hydraulic control will not be performed. The ABS will have recourse to manual braking if this occurs.

  FEATURES • Depending on the road conditions, the braking distance may be longer compared to that of vehicles not equipped with ABS. Therefore, ride at a safe speed and keep a safe distance between yourself and other vehicles. • The braking of the vehicle, even in the worst case, is principally executed when the vehicle is advanc- ing straight ahead.

  FEATURES EAS20170 FEATURES ET2D21013 OUTLINE OF THE YCC-S (Yamaha Chip Controlled-Shift) SYSTEM Concept YCC-S offers more enjoyable and easy riding by eliminating the need for the user to operate the clutch, which also reduces fatigue during long touring. YCC-S is not an automatic transmission, although it allows the user to shift gears by foot or hand ac- cording to preference.

• Page 11
  FEATURES 1. YCC-S test coupler 8. MCU (motor control unit) 2. YCC-S control relay 9. Shift actuator 3. YCC-S indicator and warning light 10. Clutch actuator 4. YCC-S motor control fuse 11. Foot shift switch 5. Hand shift switch 12. YCC-S speed sensor 6.
• Page 12
  • If the YCC-S indicator and warning light come on while riding, stop the vehicle, park it in a safe place, and then contact a Yamaha dealer. Because the YCC-S system stops automatically when the YCC-S indicator and warning light come on, it is impossible to shift since clutch operation is stopped.
