Cleaning the air filter case/duct check
hoseThere is a check hose at the bottom of the air
filter case under the cargo bed and a check
hose at the bottom of the air duct. The air duct
check hose can be accessed under the vehi-
cle. If dust or water collects in a check hose,
empty the hose and clean the air filter element
and air filter case.1. Air filter case check hose 1. Air duct check hose

EVU00780V-belt case drain plugThe V-belt case drain plug is located under
the cargo bed. (See page 4-26 for cargo bed
lifting and lowering 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.1. V-belt case drain plug

WARNING
Hot 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.1. Tailpipe bolt ( × 4)

2. Remove the tailpipe by pulling it out ofthe 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.1. Gasket 2. Spark arrester 3. Tailpipe4. Install the gasket, and then insert thetailpipe into the muffler and align the bolt
holes.
5. Install the bolts and tighten them to the specified torque.
Valve 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.

BrakesReplacement of brake components requires
professional knowledge. Brake service should
be performed by a Yamaha dealer.
WARNING
Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident.5B410019Checking 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 indica-
tor 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 8-39, 8-41 for wheel
removal and installation procedures.)

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.1. Brake pad wear indicator groove
EVU00850Checking 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.1. Minimum level mark

WARNING
Improper maintenance can result in loss of
braking ability. Observe these precau-
tions:●
Insufficient brake fluid may allow air
to enter the brake system, reducing
braking performance.
●
Clean the filler cap before removing.
Use only DOT 4 brake fluid from a
sealed container.
●
Use only the specified brake fluid;
otherwise, the rubber seals may dete-
riorate, causing leakage.
●
Refill with the same type of brake flu-
id. Adding a brake fluid other than
DOT 4 may result in a harmful chemi-
cal reaction.
●
Be careful that water does not enter
the brake fluid reservoir when refill-
ing. Water will significantly lower the
boiling point of the fluid and may re-
sult in vapor lock.
NOTICEBrake 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.EVU00860Brake 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.
