HOW TO USE THIS MANUAL
This manual is intended as a handy, easy-to-read reference book for the mechanic. Comprehensive
explanations of all installation, removal, disassembly, assembly, repair and check procedures are
laid out with the individual steps in sequential order.
The manual is divided into chapters. An abbreviation and symbol in the upper right corner of
each page indicate the current chapter.
Refer to “SYMBOLS”.
Each chapter is divided into sections. The current section title is shown at the top of each page,
except in Chapter 3 (“PERIODIC CHECKS AND ADJUSTMENTS”), where the sub-section title(s)
appears.
Sub-section titles appear in smaller print than the section title.
To help identify parts and clarify procedure steps, there are exploded diagrams at the start of
each removal and disassembly section.
Numbers are given in the order of the jobs in the exploded diagram. A circled number indicates a
disassembly step.
Symbols indicate parts to be lubricated or replaced.
Refer to “SYMBOLS”.
A job instruction chart accompanies the exploded diagram, providing the order of jobs, names of
parts, notes in jobs, etc.
Jobs requiring more information (such as special tools and technical data) are described
sequentially.

NOTE:
1. Insert the front wheel axle from the right
side and tighten it with the flange bolt from
the left side to 91 Nm (9.1 m•kg, 66 ft•lb).
2. In the order from the pinch bolt
→ pinch
bolt
→ pinch bolt , tighten each bolt to
21 Nm (2.1 m•kg, 15 ft•lb) without performing temporary tightening.
3. Check that the end face of the axle head
and the end face of the fork side are flushmounted. If they are out of alignment, make
sure to fit them by adding the external force
by hand or with a plastic hammer, etc.
If the end face of the axle is not parallel to
the end face of the fork, align them so that
one point of the axle circumference is positioned on the end face of the fork.
At this stage, it can be accepted if the end
face of the axle becomes partially concave
to the end face of the fork.
4. In the order from the pinch bolt
→ pinch
bolt
→ pinch bolt , tighten each bolt to
21 Nm (2.1 m•kg, 15 ft•lb) without performing temporary tightening.

BLEEDING THE HYDRAULIC BRAKE SYSTEM
CHK

EAS00135
PERIODIC CHECKS AND
ADJUSTMENTS
BLEEDING THE HYDRAULIC BRAKE
SYSTEM
WARNING
Bleed the hydraulic brake system whenever:
• the system is disassembled.
• a brake hose is loosened, disconnected or
replaced.
• the brake fluid level is very low.
• brake operation is faulty.
NOTE:
• Be careful not to spill any brake fluid or allow
the brake fluid reservoir to overflow.
• When bleeding the hydraulic brake system,
make sure there is always enough brake fluid
before applying the brake. Ignoring this precaution could allow air to enter the hydraulic
brake system, considerably lengthening the
bleeding procedure.
• If bleeding is difficult, it may be necessary 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. Fill the brake fluid reservoir to the proper
level with the recommended brake fluid.
b. Install the brake fluid reservoir diaphragm.
c. Connect a clear plastic hose
tightly to
the bleed screw .
Front brake master cylinder
Front brake caliper
Rear brake caliper
NOTE:
Bleeding order of the front hydraulic brake system is the following order:
1. front brake master cylinder.
2. front brake calipers.
3. front brake master cylinder.
d. Place the other end of the hose into a container.
e. Slowly apply the brake several times.
20
BLEEDING THE HYDRAULIC BRAKE SYSTEM
CHK
ADJ
f.
Fully pull the brake lever or fully press
down the brake pedal and hold it in position.
g. Loosen the bleed screw.
NOTE:
Loosening the bleed screw will release the
pressure and cause the brake lever to contact
the throttle grip or the brake pedal to fully
extend.
h. Tighten the bleed screw and then release
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 specification.
Bleed screw
6 Nm (0.6 m•kg, 4.3 ft•lb)
k. Fill the brake fluid reservoir to the proper
level with the recommended brake fluid.
Refer to “CHECKING THE BRAKE FLUID
LEVEL”.
WARNING
After bleeding the hydraulic brake system,
check the brake operation.
NOTE:
After bleeding air, the brake fluid may ooze
around the thread section of each bleed screw.
This phenomenon does not show the leakage
but the brake fluid that has been accumulated
in the thread of screw while bleeding air.
Please wipe off to make the parts clean.

WARNING
• Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to

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 brake fluid reservoir. Water
will significantly lower the boiling point of
the brake fluid and could cause vapor
lock.
CAUTION:
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
5. Bleed:

of the
roller and calculate the dimension between
pin centers.
• Dimension
between pin centers = (Inner
dimension
+ Outer dimension ) / 2

chain, front drive sprocket and rear drive
sprocket as a set.

(maximum)
239.3 mm (9.42 in)
NOTE:
• While measuring the 15-link section, push
down on the drive chain to increase its tension.
• Perform this measurement at two or three different places.
2. Check:
• drive chain
Stiffness → Clean and lubricate or replace.
3. Clean:
• drive chain
a. Wipe the drive chain with a clean cloth.
b. Put the drive chain in kerosene and remove
any remaining dirt.
c. Remove the drive chain from the kerosene
and completely dry it.

SWINGARM AND DRIVE CHAIN
CHAS
CAUTION:
This motorcycle has a drive chain with
small rubber O-rings
between the drive
chain side plates. Never use high-pressure
water or air, steam, gasoline, certain solvents (e.g., benzine), or a coarse brush to
clean the drive chain. High-pressure methods could force dirt or water into the drive
chain’s internals, and solvents will deteriorate the O-rings. A coarse brush can also
damage the O-rings. Therefore, use only
kerosine to clean the drive chain.
4. Check:
• O-rings
Damage → Replace the drive chain.
• drive chain rollers
Damage / wear → Replace the drive chain.
• drive chain side plates
Damage / wear → Replace the drive chain.
Cracks → Replace the drive chain and
make sure that the battery breather hose is
properly routed away from the drive chain
and below the swingarm.
5. Lubricate:
• drive chain
Recommended lubricant
Engine oil or chain lubricant
suitable for O-ring chains
6. Check:
• drive sprocket
• rear wheel sprocket
More than 1 / 4 tooth
wear → Replace the
drive chain sprockets as a set.
Bent teeth → Replace the drive chain
sprockets as a set.
