its from the spark arrester portion of the
tailpipe and inside of the tailpipe housing. 5. Install the gasket, and then insert the tail-
pipe into the muffler and align the bolt
holes.

use, resulting in improper fuel/air supply or
engine noise. To preven t this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a
professional Yamaha service technician.EBU32470BrakesReplacement of brake components requires
professional knowledge. Brake service
should be performed by a Yamaha dealer.
WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident. EBU35150Checking the front and rear brake padsCheck each brake pad for damage and mea-
sure the lining thickness. If a brake pad is
damaged or if the lining thickness is less than
1.0 mm (0.04 in), have a Yamaha dealer re-
place the brake pads as a set.
The wheels need to be removed to check the
brake pads. (See pages 8-57, 8-59 for wheel
removal and installation procedures.)
Tightening torque: Tailpipe cover bolt:8 N·m (0.8 kgf·m, 5.9 lb·ft)

EBU32490Checking the parking brake padsEach brake pad is provided with a wear indi-
cator groove, which allows you to check the
brake pad wear without having to disassem-
ble the brake. If a brake pad has worn to the
point that the wear indicator groove has al-
most disappeared, have a Yamaha dealer re-
place the brake pads as a set.
EBU36610Checking the brake and YCC-S clutch
fluid levelsBefore starting off, check that the brake and
YCC-S clutch fluids are above the minimum
level marks. Replenish the brake and YCC-S
clutch fluids if necessary.

TIPThe brake and YCC-S clutch fluid reser-
voirs are located under the hood (page
8-11).
 For an accurate reading, make sure the ve-
hicle is parked on a level surface.
WARNING
EWB04160Improper maintenance can result in loss of
braking ability or YCC-S clutch operation.
Observe these precautions:
 Insufficient brake or YCC-S clutch fluid
may allow air to enter the brake or
YCC-S clutch system, reducing braking
or YCC-S clutch performance.
 Clean the filler caps before removing.
Use only DOT 4 brake fluid from a sealed
container.
 Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
 Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion.

Be careful that water or dust does not
enter the brake or YCC-S clutch fluid
reservoir when refilling. Water will signif-
icantly lower the boiling point of the fluid
and may result in vapor lock. NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately. As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads or brake system l eakage; therefore, be
sure to check the brake pads for wear and the
brake system for leakage. A low YCC-S
clutch fluid level may indicate YCC-S clutch
system leakage; therefore, be sure to check
the YCC-S clutch system for leakage. If the
brake or YCC-S clutch fluid level goes down suddenly, have a Yamaha dealer check and
repair the vehicle before any further opera-
tion.
EBU36550Brake and YCC-S clutch fluid replace-
mentComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.

Replace the oil seals every two years.
 Replace the brake and YCC-S clutch hoses
every four years.EBU36540YCC-S clutchThis model is equipped with a hydraulic
clutch, therefore, it is necessary to check the
YCC-S clutch fluid level and check the hy-
draulic system for leakage before each drive.
If the YCC-S clutch plates wear out, shifting
becomes rough or clutch slippage will occur,

causing poor acceleration. If any of the above
occurs, have a Yamaha dealer check the
YCC-S clutch.EBU32530Checking the brake pedalHave a Yamaha dealer check the brakes at
the intervals specified in the periodic mainte-
nance and lubrication chart. There should be
no free play in the brake pedal. The brakes
should operate smoothly and there should be
no brake drag. If the brakes feel soft or
spongy, this could indicate air in the brake
system. Have a Yamaha dealer check the
brake system if necessary.
EBU35821Checking the accelerator pedalThe accelerator pedal should operate
smoothly and spring back to position when
released. If the pedal free play is out of spec-
ification, have a Yamaha dealer adjust or re-
place the throttle wire.1. Brake pedal

EBU35194Parking brake lever free play adjust-
mentPeriodically check the parking brake lever
free play and adjust it if necessary.1. Shift the transmission into first gear.
2. Check the parking brake lever free play.
The maximum free play is equal to one
click of the parking brake lever. If neces-
sary, adjust the free play as follows. 3. Remove panel B.
(See page 8-11.)
4. Release the parking brake lever.
5. Slide the rubber cover back on the park- ing brake cable.

7. Turn the adjusting nut in direction (a) toincrease the free play or in direction (b) to
decrease the free play.
8. Tighten the locknut, and then slide the
rubber cover to its original position.
9. Install the panel.
EBU36620Brake light switchThe brake light, which is activated by the
brake pedal, should come on just before
braking takes effect. Since the brake light
switch is a component of the YCC-S system,
it must be adjusted by a Yamaha dealer, who
has the necessary professional knowledge
and experience.EBU35930Cable inspection and lubrication
WARNING
EWB03380Damaged cables could restrict operation,
which may cause an accident or injury. In-
spect control cables frequently and re-
place damaged cables. Corrosion can
result when the outer covering of control
cables becomes damaged. Cables can
also become frayed or kinked.
