2. Remove the final gear oil filler bolt and itsgasket, and then check the oil level in the
final gear case. The oil level should be at
the brim of the filler hole.
3. If the oil is below the brim of the filler hole, add sufficient oil of the recommended
type to raise it to the correct level.
4. Check the gasket for damage, and re- place it if necessary. 5. Install the oil filler bolt and its gasket, and
then tighten the bolt to the specified
torque.
Changing the final gear oil 1. Park the vehicle on a level surface.
2. Place an oil pan under the final gear case
to collect the used oil.
3. Remove the final gear oil filler bolt, the fi-
nal gear oil drain bolt and their gasket to
drain the oil.1. Final gear oil

TIPIf the recommended gear oil is not available,
SAE 80W-90 API GL-4 or GL-5 hypoid gear
oil may be used instead. Checking the differential gear oil level1. Park the vehicle on a level surface.
2. Remove the differential gear oil filler bolt and its gasket, and then check the oil lev-
el. It should be up to the brim of the filler
hole. 3. If the level is low, add sufficient oil of the
recommended type to raise it to the
specified level.
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.

9. Thoroughly apply Yamalube foam air filteroil (or other quality liquid foam air filter—
do not use a spray-type product) to the
foam material. The foam air filter element
should be wet but not dripping.
10. Pull the foam air filter element over its frame.
11. Install the air filter.
12. 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. 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 clutch fluid reservoir
when refilling. Water 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 or brake system leakage; therefore, be
sure to check the brake pads for wear and the
brake system for leakage. A low clutch fluid
level may indicate clutch system leakage;
therefore, be sure to check the clutch system
for leakage. If the brake or clutch fluid level
goes down suddenly, have a Yamaha dealer
check and repair the vehicle before any fur-
ther operation.
EBU35170Brake and clutch 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 and clutch hoses every
four years.EBU35182Checking the clutch pedalThe clutch pedal should operate smoothly
and spring back to position when released.
When depressed, it should offer resistance
before reaching the floorboard. If the pedal
offers little resistance when depressed, or if
the transmission grinds gears when shifting,
have a Yamaha dealer check the vehicle.
