Install the center bottom panel by installing
the bolts, and then tightening them to the
specified torque.
EBU33690V-belt case drain plugThe V-belt case drain plug is located behind
the left panel. (See page 8-11 for left panel re-
moval and installation procedures.)
After riding in water deep enough to allow wa-
ter to enter the V-belt case, remove the drain
plug to drain any water from the case.
If water drains from the V-belt case after re-
moving the drain plug, have a Yamaha dealer
inspect the vehicle, as the water may affect
other engine parts.

EBU32450Cleaning the spark arrester
WARNING
EWB03370Hot exhaust system may cause burns. To
avoid burns or fires, make sure that the en-
gine is stopped and the exhaust system is
cool before cleaning the spark arrester. Do
not start the engine while cleaning the ex-
haust system. 1. Remove the tailpipe bolts.2. Remove the tailpipe by pulling it out of
the muffler, and then remove the gasket.
3. Tap the tailpipe lightly, and then use a wire brush to remove any carbon depos-
its from the spark arrester portion of the
tailpipe and inside of the tailpipe housing.
4. Install the gasket, and then insert the tail- pipe into the muffler and align the bolt
holes.
5. Install the bolts and tighten them to the
specified torque.1. Tailpipe bolt

EBU32460Valve clearanceThe correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent 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.
EBU32480Checking the front and rear brake padsEach brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to the point that the wear indi-
cator grooves have almost disappeared, have
a Yamaha dealer replace the brake pads as a
set.
The wheels need to be removed to check the
brake pads. (See pages 8-47, 8-49 for wheel
removal and installation procedures.)

EBU32500Checking the brake fluid levelBefore riding, check that the brake fluid is
above the minimum level mark. Check the
brake fluid level with the top of the reservoir
level. Replenish the brake fluid if necessary.
WARNING
EWB02721Improper maintenance can result in loss of
braking ability. Observe these precau-
tions:
Insufficient brake fluid may allow air to
enter the brake system, reducing brak-
ing performance.

Clean the filler cap 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 does not enter the
brake fluid reservoir when refilling. Wa-
ter will significantly 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 and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check the cause before further riding.EBU32520Brake fluid replacementComplete 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 hoses every four years.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.EBU33710Parking brakePull the parking brake lever rearward com-
pletely. If the parking brake lever clicks eight
times or more, have a Yamaha dealer adjust
the parking brake because the braking forceof the parking brake is weak. In addition, have
a Yamaha dealer check and adjust the park-
ing brake at the intervals specified in the peri-
odic maintenance and lubrication chart.
EBU32550Brake light switch adjustmentThe brake light switch, which is activated by
the brake pedal, is properly adjusted when
the brake light comes on just before braking
takes effect. If necessary, adjust the brake
light switch as follows.
Turn the adjusting nut while holding the brake
light switch in place. To make the brake light
come on earlier, turn
the adjusting nut in di-
rection (a). To make the brake light come on
later, turn the adjusting nut in direction (b).

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.
Lubricate the cable ends. If the cables do not
operate smoothly, ask a Yamaha dealer to re-
place them.EBU32570Brake pedal and accelerator pedal lu-
bricationLubricate the pivoting parts.
