3. If the level is low, add sufficient oil of therecommended type to raise it to the
specified level. NOTICE: Be sure no for-
eign material enters the differential
gear case.

4. Check the gasket for damage, and re- place it if necessary.
5. Install the differential gear oil filler bolt and its gasket, and then tighten the bolt
to the specified torque. Changing the differential gear oil
1. Park the vehicle on a level surface.
2. Place an oil pan under the differential
gear case to collect the used oil.
3. Remove the differential gear oil filler bolt,
the differential gear oil drain bolt and their
gasket to drain the oil.1. Differential gear oil filler bolt

4. Install the differential gear oil drain boltand its new gasket, and then tighten the
bolt to the specified torque.
5. Refill the differential gear case with the recommended oil. NOTICE: Be sure no
foreign material enters the differential
gear case.

TIP GL-4 is a quality and additive rating; GL-5
rated hypoid gear oils may also be used.
If desired, an SAE 80W-90 hypoid gear oil
may be used instead.
6. Check the oil filler bolt gasket for dam-
age, and replace it if necessary.
7. Install the differential gear oil filler bolt and its gasket, and then tighten the bolt
to the specified torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.EBU35110CoolantCheck the coolant level prior to each time you
operate the vehicle, and have a Yamaha deal-
er change the coolant every two years.
Checking the coolant level
1. Park the vehicle on a level surface.
2. Remove the hood. (See page 8-10.)
Tightening torque: Differential gear oil drain bolt:9.8 N·m (0.98 kgf·m, 7.1 lb·ft)

10. Thoroughly apply Yamalube foam air fil-ter oil (or other quality liquid foam air fil-
ter—do not use a spray-type product) to
the foam material. The foam air filter ele-
ment should be wet but not dripping.
11. Pull the foam air filter element over its frame.
12. Install the air filter.
13. Install the air filter case cover and lock it
into place by turning the air filter case
cover lock clockwise.
TIPMake sure that the match mark on the cover
lock is aligned with the close match mark on
the air filter case cover. 14. Install the panel.EBU35130Cleaning the air filter case check hosesThere is a check hose on each side of the air
filter case. If dust or water collects in a check
hose, empty the hose and clean the air filter
element and air filter case.1. Match mark

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,
