EAU3836A
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 level1. 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 first completely 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 the
minimum and maximum level marks.
5. If the engine oil is at or below theminimum 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 portion
on the dipstick.6. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
7. Install the rider seat.

TIPThe rear brake fluid reservoir is located
under the rider seat. (See page 3-16.)
WARNING
EWA16000
Improper maintenance can result in
loss of braking ability or clutch oper-
ation. Observe these precautions:●
Insufficient brake or clutch fluid
may allow air to enter the brake
or clutch system, reducing
braking or clutch performance.
●
Clean the filler caps before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
●
Use only the specified brake flu-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
●
Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.
●
Be careful that water does not
enter the brake or clutch fluid
reservoir when refilling. Water will significantly lower the boil-
ing point of the fluid and may re-
sult in vapor lock.
NOTICE
ECA17640
Brake fluid may damage painted sur-
faces 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 indi-
cate worn brake pads and/or brake sys-
tem 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 sudden-
ly, have a Yamaha dealer check the
cause before further riding.
