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 a certain level. 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, coolant temperature sensor, lean angle sensor, crankshaft position sensor, intake air pressure sensor, intake air temperature sensor, rear wheel sensor and O
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.

ABS
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.
When wheel lock is detected during emergency braking, hydraulic control is performed by the hydraulic
system on the front and rear brakes independently.
Useful terms
• Wheel speed:
The rotation speed of the front and rear wheels.
• Chassis speed:
The speed of the chassis.
When the brakes are applied, wheel speed and chassis speed are reduced. However, the chassis
travels forward by its inertia even though the wheel speed is reduced.
• Brake force:
The force applied by braking to reduce the wheel speed.
• Wheel lock:
A condition that occurs when the rotation of one or both of the wheels has stopped, but the vehicle
continues to travel.
• 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.
Slip ratio = (Chassis speed – Wheel speed)/Chassis speed × 100 (%)
0%: There is no slipping between the wheel and the road surface. The chassis speed is equal to the
wheel speed.
100%: The wheel speed is “0”, but the chassis is moving (i.e., wheel lock).
Brake force and vehicle stability
When the brake pressure is increased, wheel speed is reduced. Slipping occurs between the tire and
the road surface and brake force is generated. The limit of this brake force is determined by the friction
force between the tire and the road surface and is closely related to wheel slippage. Wheel slippage is
represented by the slip ratio.
Side force is also closely related to wheel slippage. See figure “A”. If the brakes are applied while keeping the proper slip ratio, it is possible to obtain the maximum brake force without losing much side force.
ABS allows full use of the tires’ capabilities even on slippery road surfaces or less slippery road surfaces. See figure “B”.

Wheel slip and hydraulic control
The ABS ECU calculates the wheel speed of each wheel according to the rotation signal received from
the front and rear wheel sensors. In addition, the ABS ECU calculates the vehicle chassis speed and
the rate of speed reduction based on the wheel speed values.
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 determines that the wheel has a tendency to lock.
If the slip is large and the wheel has a tendency to lock (point “A” in the following figure), the ABS ECU
reduces the hydraulic pressure in the brake caliper. Once the ABS ECU determines that the tendency
of the wheel to lock has diminished after the hydraulic pressure is reduced, it increases the hydraulic
pressure (point “B” in the following figure). The hydraulic pressure is initially increased quickly, and then
it is increased gradually.
a. Chassis speed
b. Wheel speed
c. Brake force
ABS operation and vehicle control
If the ABS starts operating, there is a tendency of the wheel to lock, and the vehicle is approaching the
limit of control. To make the rider aware of this condition, the ABS has been designed to generate a
reaction-force pulsating action in the brake lever and brake pedal independently.
When the ABS is activated, a pulsating action may be felt at the brake lever or brake pedal, but this
does not indicate a malfunction.
The higher the side force on a tire, the less traction there is available for braking. This is true whether
the vehicle is equipped with ABS or not. Therefore, sudden braking while cornering is not recommended. Excessive side force, which ABS cannot prevent, could cause the tire to slip sideways.

WARNING
WARNING
EWA16510
The braking of the vehicle, even in the worst case, is principally executed when the vehicle is
advancing straight ahead. During a turn, sudden braking is liable to cause a loss of traction of
the tires. Even in vehicles equipped with ABS, overturning of the vehicle cannot be prevented
if it is braked suddenly.
The ABS functions to prevent the tendency of the wheel to lock by controlling the hydraulic pressure.
However, if there is a tendency of the wheel to lock on a slippery road surface, due to engine braking,
the ABS may not be able to prevent the wheel from locking.
EWA13870
The ABS controls only the tendency of the wheel to lock caused by applying the brakes. The
ABS cannot prevent wheel lock on slippery surfaces, such as ice, when it is caused by engine
braking, even if the ABS is operating.

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 condition and allows normal braking even if the ABS is not operating properly.
When this occurs, the ABS warning light on the meter assembly comes on.
The ABS stores the fault codes in the memory of the ABS ECU for easy problem identification and troubleshooting.

Wheel sensors and wheel sensor rotors
Wheel sensors “1” detect the wheel speed and transmit the rotation signal to the ABS ECU.
Each wheel sensor is composed of a permanent magnet and a hall IC. The sensor rotors “2” rotate with
the wheels. The sensor rotors “2” have 40 slots and are installed close to the wheel sensors. As the
sensor rotor rotates, the hall element in the hall IC installed in the wheel sensor generates pulses. The
pulse frequency, which is proportional to the magnetic flux density, is converted into a wave in the hall
IC so that it can be output.
The ABS ECU calculates the wheel rotation speed by detecting the pulse frequency.

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 to check the electrical circuit
and the system function (ABS self-diagnosis), and goes off when the vehicle is operated (the function
check is properly completed at a speed of about 6 to 10 km/h [3.8 to 6.3 mi/h]).
After all checks and servicing are completed, the ABS warning light will go off when the vehicle is ridden
or pushed at a speed of 7 km/h (4 mi/h) or faster.
ECA20950
If the rear wheel is raced with the vehicle on a suitable stand, the ABS warning light may flash
or come on. If this occurs, turn the main switch to “OFF”, then back to “ON”. The ABS operation
is normal if the ABS warning light goes off after the vehicle starts off. If the fault codes are not
deleted, the ABS warning light goes off after the vehicle is ridden at a speed of about 30 km/h
(19 mi/h).

Hydraulic unit assembly
The hydraulic unit assembly “1” is composed of hydraulic control valves (each with a outlet solenoid
valve and inlet solenoid valve), buffer chambers, hydraulic pumps, an ABS motor, and ABS ECU. The
hydraulic unit adjusts the front and rear wheel brake fluid pressure to control the wheel speed according
to signals transmitted from the ABS ECU.
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.
1. When the brakes are operated normally, the inlet solenoid valve “1” is open and the outlet solenoid
valve “2” is closed. The brake line between the brake master cylinder and brake caliper is open.
2. When the ABS is activated, the inlet solenoid valve “1” closes and the outlet solenoid valve “2” opens
using the power supplied from the ABS ECU signals. This reduces the hydraulic pressure.
1-10
FEATURES
3. When the ABS ECU sends a signal to stop reducing the hydraulic pressure, the outlet solenoid valve
“2” closes and the brake fluid is pressurized again. The inlet solenoid valve “1” controls the hydraulic
pressure difference between the brake fluid in the upper brake lines (brake master cylinder side) and
the brake fluid in the lower brake lines (brake caliper side).
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)
ABS ECU
The ABS ECU is integrated with the hydraulic unit to achieve a compact and lightweight design.
As shown in the following block diagram, the ABS ECU receives wheel sensor signals from the front
and rear wheels and also receives signals from other monitor circuits.

ABS control operation
The ABS control operation performed in the ABS ECU is divided into the following two parts.
• Hydraulic control
• Self-diagnosis
When a malfunction is detected in the ABS, a fault code is stored in the memory of the ABS ECU for
easy problem identification and troubleshooting.
• Some types of malfunctions are not recorded in the memory of the ABS ECU (e.g., a blown ABS con-
trol unit 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 brake lever or brake pedal is even slightly operated, a vibration can be felt at the lever and pedal,
but these do not indicate a malfunction.

ABS OPERATION
The ABS hydraulic circuit consists of two systems: the front wheel, and rear wheel. The following describes the system for the front wheel only.
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.
At this time, the inlet and outlet check valves of the hydraulic pump are closed. As a result of eliminating
the orifice, the brake master cylinder directly pressurizes the brake caliper during normal braking. When
the brake lever is released, the brake fluid in the brake caliper returns to the brake master cylinder.

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. Because the outlet solenoid valve
is open, the brake fluid is sent to the buffer chamber. As a result, the hydraulic pressure in the brake
caliper is reduced.
The brake fluid stored in the buffer chamber is pumped back to the brake master cylinder by the hydraulic pump linked to the ABS motor.

FEATURES
WARNING
ABS function
EWA16520
• When hydraulic control is performed by the ABS, the brake system alerts the rider that the
wheels have a tendency to lock by generating a reaction-force pulsating action in the brake
lever or brake pedal. When the ABS is activated, the grip between the road surface 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.
Use extreme care when operating the vehicle under these conditions.
• The ABS is not designed to shorten the braking distance or improve the cornering perfor-
mance.
• 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
advancing straight ahead. During a turn, sudden braking is liable to cause a loss of traction of
the tires. Even vehicles equipped with ABS cannot be prevented from falling over if braked
suddenly.
• The ABS does not work when the main switch is turned to “OFF”. The conventional braking
function can be used.
* Wheel lock: A condition that occurs when the rotation of one or both of the wheels has
stopped, but the vehicle continues to travel.

Consider the following tips to reduce fuel consumption:
• Avoid high engine speeds during acceleration.
• Travel at a constant speed.
• Select the transmission gear that is appropriate for the vehicle speed.
1. Fuel meter
2. Fuel level warning indicator “ ”
The fuel meter indicates the amount of fuel in the
fuel tank. The display segments of the fuel meter
disappear towards “E” (Empty) as the fuel level
decreases. When the last segment and fuel level
warning indicator “ ” start flashing, refuel as
soon as possible.
This fuel meter is equipped with a self-diagnosis
system. If a problem is detected in the electrical
circuit, the following cycle is repeated until the
malfunction is corrected: fuel level segments
and fuel level warning indicator “ ” flash eight
times, then go off for approximately 3 seconds.
If this occurs, check the electrical circuit. Refer to
“SIGNALING SYSTEM” on page 8-21.

FEATURES
If the fuel level warning indicator “ ” and left
segment of the fuel meter start flashing, the display automatically changes to the fuel reserve
tripmeter mode “TRIP F” and starts counting the
distance traveled from that point. In that case,
push the left set button to switch the display between the various tripmeter, odometer, instantaneous fuel consumption and average fuel
consumption modes in the following order:
1. Multi-function display
The multi-function display is equipped with the
following:
• an odometer
• two tripmeters (which show the distance traveled since they were last set to zero)
• a fuel reserve tripmeter (which shows the distance traveled since the left segment of the fuel
meter started flashing)
• a coolant temperature display
• an ambient temperature display
• an instantaneous fuel consumption display
• an average fuel consumption display
Push the left set button to switch the display between the odometer mode “ODO”, tripmeter
mode “TRIP 1” and “TRIP 2”, instantaneous fuel
consumption mode “km/L” or “L/100 km”, average fuel consumption mode “AVE_ _._ km/L” or
“AVE_ _._ L/100 km”, coolant temperature
mode “_ _ °C”, and ambient temperature mode
“Air_ _ °C” in the following order:
ODO → TRIP 1 → TRIP 2 → km/L or L/100 km
→ AVE_ _._ km/L or AVE_ _._ L/100 km → _ _
°C → Air_ _ °C → ODO
TRIP F → km/L or L/100 km → AVE_ _._ km/L
or AVE_ _._ L/100 km → _ _ °C → Air_ _ °C →
ODO → TRIP 1 → TRIP 2 → TRIP F
For the UK only:
TRIP F → km/L, L/100 km or MPG → AVE_ _._
km/L, AVE_ _._ L/100 km or AVE_ _._ MPG →
_ _ °C → Air_ _ °C → ODO → TRIP 1 → TRIP
2 → TRIP F
To reset a tripmeter, select it by pushing the left
set button, and then push the right set button for
at least one second.
If you do not reset the fuel reserve tripmeter
manually, it resets itself automatically and the
display returns to the prior mode after refueling
and traveling 5 km (3 mi).
Instantaneous fuel consumption display
For the UK only:
Push the left set button to switch the display between the odometer mode “ODO”, tripmeter
mode “TRIP 1” and “TRIP 2”, instantaneous fuel
consumption mode “km/L”, “L/100 km” or
“MPG”, average fuel consumption mode “AVE_
_._ km/L”, “AVE_ _._ L/100 km” or “AVE_ _._
MPG”, coolant temperature mode “_ _ °C”, and
ambient temperature mode “Air_ _ °C” in the following order:
ODO → TRIP 1 → TRIP 2 → km/L, L/100 km or
MPG → AVE_ _._ km/L, AVE_ _._ L/100 km or
AVE_ _._ MPG → _ _ °C → Air_ _ °C → ODO
Push the right set button to switch the display in
the reverse order.
1. Instantaneous fuel consumption display
The instantaneous fuel consumption display can
be set to either “km/L”, “L/100 km” or “MPG” (for
the UK only).
• “km/L”: The distance that can be traveled on
1.0 L of fuel under the current riding conditions
is shown.
• “L/100 km”: The amount of fuel necessary to
travel 100 km under the current riding conditions is shown.
• “MPG” (for the UK only): The distance that can
be traveled on 1.0 Imp.gal of fuel under the current riding conditions is shown.

Average fuel consumption mode
1. Average fuel consumption display
The average fuel consumption display can be
set to either “AVE_ _._ km/L”, “AVE_ _._ L/100
km” or “AVE_ _._ MPG” (for the UK only).
This display shows the average fuel consumption since it was last reset.
• “AVE_ _._ km/L”: The average distance that
can be traveled on 1.0 L of fuel is shown.
• “AVE_ _._ L/100 km”: The average amount of
fuel necessary to travel 100 km is shown.
• “AVE_ _._ MPG” (for the UK only): The average distance that can be traveled on 1.0
Imp.gal of fuel is shown.
To switch between the average fuel consumption displays, push the left set button for one second when one of the displays is shown.
To reset the average fuel consumption display,
