Engine oil and oil filter car-
tridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion. A slight tilt to the side can
result in a false reading.
2. Remove the rider seat. (See page
3-16.)
3. Start the engine, warm it up until
the engine oil has reached a nor-
mal temperature of 60 °C (140 °F),
let it continue to idle for ten sec-
onds, and then turn the engine off.TIPTo achieve the proper engine oil tem-
perature for an accurate oil level read-
ing, the engine must have firstcompletely cooled down, and then
warmed up again for several minutes to
normal operating temperature.
4. Wait a few minutes until the oil set-
tles, remove the oil filler cap, wipe
the engine oil dipstick clean, insert
it back into the oil filler hole (with-
out screwing it in), and then re-
move it again to check the oil level.TIPThe engine oil should be between theminimum and maximum level marks.
5. If the engine oil is at or below the
minimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
TIPWhen adding oil, be careful not to over-
fill the engine oil tank; the oil level rises
faster starting from the half level portionon the dipstick.
6. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
7. Install the rider seat.

PERIODIC MAINTENANCE AND ADJUSTMENT

6Observe these precautions:
When checking the brake and
clutch fluid levels, make sure that
the top of each reservoir is level.
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.
Be careful that water does not en-
ter the brake or clutch fluid reser-
voir when refilling. Water will
significantly lower the boiling point
of the fluid and may result in vapor
lock.
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
EAU22751
Changing the brake and
clutch fluids Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the TIP after the periodic
maintenance and lubrication chart. In
addition, have the oil seals of the brake
and clutch master cylinders and cali-
pers as well as the brake and clutch
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.
Oil seals: Replace every two
years.
Brake and clutch hoses: Replace
every four years.
Recommended brake and clutch flu-
id:
DOT 4 brake fluid
