ADJUSTING THE FRONT BRAKE

CHASSIS
ADJUSTING THE FRONT BRAKE
1. Adjust:
• Brake lever position
(distance abetween the brake lever and
the handlebar grip)
a. Turn the adjusting dial 1while holding the
lever pushed away from the handlebar grip
NOTE:
Align the setting on the adjusting dial with the
arrow mark 2
WARNING
After adjusting the brake lever position, make
sure the pin on the brake lever holder is firm-
ly inserted in the hole in the adjusting dial.
WARNING
A soft or spongy feeling in the brake lever can
indicate the presence of air in the brake sys-
tem. Before the vehicle is operated, the air
must be removed by bleeding the brake sys-
tem. Air in the brake system will considerably
reduce braking performance and could result
in loss of control and possibly an accident.
Therefore, inspect and, if necessary, bleed the
brake system. After adjusting the brake lever
free play, make sure that there is no brake
drag.

ADJUSTING THE REAR BRAKE
1. Check:
•Brake pedal position
(distance afrom the top of the rider
footrest to the top of the brake pedal)
Out of specification ➔Adjust.
2. Adjust:
•Brake pedal position
•Tighten lock nut.
After adjusting the brake pedal position, make
sure the brake doesn't oppose resistance.
CAUTION:
•Loosen lock nut (1).
•Turn the adjuster (2) either way to obtain the
correct pedal height.
WARNING
If the brake brake pedal has a soft or slack
feel, this means that there is air in the brake
system. It should be bled away before using
the motorcycle. Air in the system seriously
affects the effectiveness of braking and may
cause loss of control of the motorcycle.

CHECKING THE BRAKE FLUID LEVEL

CHECKING THE BRAKE FLUID LEVEL
1. Stand the motorcycle on a level surface.
NOTE:
•Place the motorcycle on a suitable stand.
•Make sure that the motorcycle is upright.
2. Check:
•Brake fluid level
Below the minimum level mark a➔Add
the recommended brake fluid to the prop-
er level.
[A] Front brake
[B] Rear brake
WARNING
•Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.
•Refill with the same type of brake fluid that
is already in the system. Mixing brake flu-
ids may result in a harmful chemical reac-
tion, leading to poor brake performance.
•When refilling, be careful that water does
not enter the reservoir. Water will signifi-
cantly lower the boiling point of the brake
fluid and could cause vapor lock.
Brake fluid may damage painted surfaces and
plastic parts. Therefore, always clean up any
spilt brake fluid immediately.
NOTE:
In order to ensure a correct reading of the brake
fluid level, make sure that the top of the reservoir
is horizontal.
CAUTION:
Recommended brake fluid:

BRAKE CIRCUIT BLEEDING
WARNING
If the brake lever or brake pedal has a soft or
slack feel, this means that there is air in the
brake system. It should be bled away before
using the motorcycle. Air in the system seri-
ously affects the effectiveness of braking and
may cause loss of control of the motorcycle.
In all cases, bleed the brake system if:
•The system has been disassembled.
•A brake hose has been loosened or
removed.
•The brake fluid in the tank is at a very low
level.
•Brake operation is faulty.
Air bleeding procedures:
a. Top up the level of the fluid in the tank to max-
imum.
b. Install the diaphragm. Be careful not to spill
fluid or let it overflow from the tank.
c. Connect the clear plastic hose (1) to the
caliper bleeder screw.
[A] Front
[B] Rear
d. Place the other end of the hose in a container.
e. Slowly pull the brake lever or press the brake
pedal several times.
f. Pull the brake lever right in or press the pedal
right down and hold in position.
g. Loosen the bleeder screw and allow the lever
or pedal to travel slowly towards its limit.
h. Tighten the bleeder screw when the lever or
pedal limit has been reached, then release the
lever or pedal.
Bleeder screw:
14 Nm (1.4 mkg)
i. Repeat operations (e) to (h) until all the air
bubbles have disappeared from the clear
plastic hose (1).

DRIVE CHAIN SLACK INSPECTION AND ADJUSTMENT

NOTE:
If bleeing proves difficult, it may be necessary to
allow the brake fluid system to stabilise for a few
hours. Repeat the bleeding procedure when the
tiny bubbles in the system have disappeared.
j. Top up fluid to the maximum level.
DRIVE CHAIN SLACK INSPECTION AND
ADJUSTMENT
Inspecting slack:
NOTE:
Before checking and/or adjusting the chain, rotate
the rear wheel through several revolutions and
check the slack several times to find the point on
the wheel where chain slack is highest.
Check and/or adjust chain slack with rear wheel in
this “tight chain” position.
Drive chain slack:
30 ~ 40 mm
NOTE:
To check chain slack, the motorcycle must stand
in an upright position with its two wheels touching
the ground and no one sitting on it. Check slack in
the position shown in the figure.
2. Adjust:
•Drive chain slack
Slack adjustment:
Too little chain slack will overload the engine
and other vital parts. Keep the slack within the
specified limits.
CAUTION: 1. Check:
•Drive chain slack (a)
Out of specification ➔Adjust.

•Turn each adjusting bolt exactly the same
amount to maintain correct axle alignment.
There are marks on each side of the
swingarm. Use these marks to align the rear
wheel.
DRIVE CHAIN LUBRICATION
The chain consists of many parts which work with
each other. If the chain is not maintained properly,
it will wear out quickly. Therefore, the chain must
be serviced regularly. This service is especially
necessary when riding in dusty areas. This motor-
cycle has a drive chain with small rubber O-Rings
between the chain plates. Steam cleaning, high-
pressure washing and certain solvents can dam-
age these O-Rings. Use only kerosene to clean
the drive chain. Wipe it dry, and thoroughly lubri-
cate it with SAE 80 ~ 90W motor oil or special lu-
bricant for O-Ring chains. Do not use any other lu-
bricants on the drive chain. They may contain sol-
vents that could damage the O-Rings.
Recommended lubricant:
SAE 80W/90 engine oil or
special lubricant for
O-Ring chains.
(1) O-Rings
•Loosen the axle nut (1).
•Loosen the locknuts (2) on each side. To tight-
en the chain, turn the chain adjusting bolts (3)
in direction (a). Loosen the locknuts on each
side. To loosen the chain, turn the chain
adjusting bolts in direction (b) and push the
wheel forward.
•After adjusting, tighten the locknuts (2). Then
tighten the axle nut (1) to the specified torque.
