2. Adjust:
• rear brake light operation timing
a. Hold the main body (1) of the rear
brake light switch so that it does not ro-
tate and turn the adjusting nut (2) in di-
rection (a) or (b) until the rear brake
light comes on at the proper time.
Direction (a)
Brake light comes on sooner.
Direction (b)
Brake light comes on later.

I. CHECKING THE BRAKE FLUID
LEVEL
1. Stand the vehicle on a level surface.
• Place the vehicle on a suitable stand.
• Make sure that the vehicle is upright.
2. Check:
• brake fluid level
Below the minimum level mark (a) →
Add the recommended brake fluid to
the proper level.
Recommended brake fluid
DOT 4
• Use only designated brake fluid. Oth-
er 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 fluids may result in a harmful
chemical reaction, leading to poor
brake performance.
• When refilling, be careful that water
does not enter the reservoir. Water
will significantly lower the boiling
point of the brake fluid and could
cause vapor lock.
Brake fluid may damage painted surfac-
es and plastic parts. Therefore, always
clean up any split brake fluid immedi-
ately.
In order to ensure a correct reading of the
brake fluid level, make sure that the top of
the reservoir is level.

J. BLEEDING THE HYDRAULIC
BRAKE SYSTEM
Bleed the hydraulic brake system when-
ever:
• the system was disassembled,
• a brake hose was loosened or re-
moved,
• the brake fluid level is very low,
• brake operation is faulty.
• Be careful not to spill any brake fluid or
allow the brake fluid reservoir to over-
flow.
• When bleeding the hydraulic brake sys-
tem, make sure that there is always
enough brake fluid before applying the
brake. Ignoring this precaution could al-
low air to enter the hydraulic brake sys-
tem, considerably lengthening the
bleeding procedure.
• If bleeding is difficult, it may be neces-
sary to let the brake fluid settle for a few
hours. Repeat the bleeding procedure
when the tiny bubbles in the hose have
disappeared.
1. Bleed:
• hydraulic brake system
a. Add the recommended brake fluid to
the proper level.
b. Install the brake fluid reservoir dia-
phragm.
c. Connect a clear plastic hose (1) tightly
to the bleed screw (2).

The bleeding order of the front hydraulic
brake system is the following:
• Front brake master cylinder
• Front brake calipers
• Front brake master cylinder
d. Place the other end of the hose into a
container.
e. Slowly apply the brake several times.
f.
Fully squeeze the brake lever or fully
depress the brake pedal and hold it in
position.
g. Loosen the bleed screw. This will re-
lease the tension and cause the brake
lever to contact the throttle grip or the
brake pedal to fully extend.
h. Tighten the bleed screw and then re-
lease the brake lever or brake pedal.
i.
Repeat steps (e) to (h) until all of the air
bubbles have disappeared from the
brake fluid in the plastic hose.
j.
Tighten the bleed screw to specifica-
tion.

Brake master cylinder
6 Nm (0.6 m•kgf, 4.3 ft•lbf)
k. Fill the reservoir to the proper level.
Refer to "CHECKING THE BRAKE
FLUID LEVEL".
After bleeding the hydraulic brake sys-
tem, check the brake operation.

K. ADJUSTING THE CLUTCH CA-
BLE FREE PLAY
1. Measure:
• clutch cable free play (a)
Out of specification → Adjust.

clutch lever)
10–15 mm (0.39–0.59 in)
