oil at the intervals specified in the general
maintenance and lubrication chart.
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. 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.
NOTICE: Be sure no foreign material
enters the final gear case.

gear oil at the intervals specified in the gener-
al maintenance and lubrication chart.
Checking the differential gear oil level
1. 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. NOTICE: Be sure no for-
eign 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.
EBU33660CoolantThe coolant level should be checked before
each ride. In addition, the coolant must be
changed at the intervals specified in the peri-
odic maintenance and lubrication chart.
Checking the coolant level1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture.TIPThe coolant should be between the minimum
and maximum level marks.
Recommended oil:SAE 80 API GL-4 Hypoid gear oil
Oil quantity: 0.18 L (0.19 US qt, 0.16 Imp.qt)
Tightening torque: Differential gear oil filler bolt:23 N·m (2.3 kgf·m, 17 lb·ft)

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 pe riodic 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.1. Brake pedal
2. No brake pedal free play

Wolverine to widen the track width. Install-
ing wheels improperly increases the risk of
wheel failure and accidents. EBU32640BatteryThe battery is located under the hood. (See
page 8-10 for hood removal and installation
procedures.)
This model is equipped with a VRLA (Valve
Regulated Lead Acid) battery. There is no
need to check the electrolyte or to add dis-
tilled water. However, the battery lead con-
nections need to be checked and, if
necessary, tightened.
WARNING
EWB03410Avoid battery contact with skin, eyes, or
clothing. Shield eyes when working near
batteries. Keep out of reach of children.
You could be poisoned or severely burned
by the sulfuric acid in battery electrolyte. In

INTERNAL: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg, or vegetable oil. Get prompt
medical attention.
EYES: Flush with water for 15 minutes and
get prompt medical attention.
