Changing the final gear oil1. 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. 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. NOTICE:
Be sure no foreign material enters the
final gear case.

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 isfound, check for the cause.EBU32380Differential gear oilChecking 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. NOTICE: Be sure no for-
eign material enters the differential
gear case.

8. Check for oil leakage. If oil leakage isfound, 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.
3. If the coolant is at or below the minimum
level mark, remove the coolant reservoir
cap, add coolant to the maximum level
mark, and install the reservoir cap.

11. Thoroughly apply Yamaha foam air filteroil or other quality liquid foam air filter oil
(not spray type) to the sponge material.
The sponge material should be wet but
not dripping.
12. Pull the sponge material over its frame.
13. Install the air filt er element holder.
14. Install the air filter element.
15. Fit the holders on the air filter case cover
onto the projections on the air filter case,
and then install the air filter case cover by
hooking the holders onto the cover. 16. Install the storage compartment as
shown.
EBU33672Cleaning the air filter case/air duct
check hoseThere is a check hose at the bottom of the air
filter case and at the bottom of the air duct.
The check hoses can be accessed under the
vehicle. If dust or water collects in a check
hose, empty the hose and clean the air filter
element and air filter case.

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 the cause before further riding.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.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
