TIPBe sure to wipe off spilled oil on any parts af-
ter the engine and exhaust system have
cooled down. 14. Start the engine, and then let it idle forseveral minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.
15. Turn the engine off, wait at least 10 minu-
tes, and then check the oil level and cor-
rect it if necessary.
16. Install the rubber cover.
17. Install the passenger seat cushion.EBU36051Final gear oilCheck the oil level and change the final gear
oil at the intervals specified in the general
maintenance and lubrication chart.
NOTICEECB03590When checking or changing the final gear
oil, make sure that no foreign material en-
ters the final gear case. If necessary, clean
the final gear oil filler bolt and surrounding
area. Checking the final gear oil level 1. Park the vehicle on a level surface.
2. Remove the final gear oil filler bolt and its
gasket, and then check the oil level in the
final gear case. The oil level should be at
the brim of the filler hole.
Recommended oil:SAE 80 API GL-4 Hypoid gear oil

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

4. Install the drain bolt and its new gasket,and then tighten the bolt to the specified
torque.
5. Refill with the recommended final gear oil up to the brim of the filler hole.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 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.
EBU36061Differential gear oilCheck the oil level and change the differential
gear oil at the intervals specified in the gener-
al maintenance and lubrication chart.NOTICEECB03600When checking or changing the differen-
tial gear oil, make sure that no foreign ma-
terial enters the differential gear case. If
necessary, clean the differential gear oil
filler bolt and surrounding area.
Tightening torque:Final gear oil drain bolt:22 N·m (2.2 kgf·m, 16 lb·ft)
Tightening torque: Final gear oil filler bolt:23 N·m (2.3 kgf·m, 17 lb·ft)

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.

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 and repair the vehicle before
any further operation.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.
