CAUTION:
Never turn an adjusting mechanism beyond
the minimum and maximum settings.
NOTE:
Although the total number of clicks of a damp-
ing force adjusting mechanism may not exact-
ly match the above specifications due to small
differences in production, the actual number of
clicks always represents the entire adjusting
range. To obtain a precise adjustment, it would
be advisable to check the number of clicks of
each damping force adjusting mechanism and
to modify the specifications as necessary.
WARNING
Suspension components become hot during
operation. Never touch the damping force ad-
justing mechanisms or the oil reservoir with
your bare hand or skin until suspension com-
ponents have cooled.

Engine oil and oil filter cartridge
The engine oil level should be checked before
each ride. In addition, the oil must be changed
and the oil filter cartridge replaced at the inter-
vals specified in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Start the engine, warm it up until the en-
gine oil has reached a normal tempera-
ture of 60˚C, let it continue to idle for ten
seconds, and then turn the engine off.
NOTE:
To achieve the proper engine oil temperature
for an accurate oil level reading, the engine
must have first completely cooled down, and
then warmed up again for several minutes to
normal operating temperature.
3. Wait a few minutes until the oil settles, re-
move the engine oil tank filler cap, wipe
the dipstick clean, insert it back into the
filler hole (without screwing it in), and
then remove it again to check the oil level.

4. Remove the crankcase drain bolt.
5. Check the washer for damage, and re-
place it if necessary.
6. Remove the engine oil tank filler cap and
the drain bolt.
NOTE:
Skip steps 7–8 if the oil filter cartridge is not be-
ing replaced.

11. Start the engine, and then let it idle for
several minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.
12. Turn the engine off, and then check the oil
level and correct it if necessary.

3. Refill with the same type of brake fluid.
Mixing fluids may result in a harmful
chemical reaction and lead to poor brake
performance.
4. Be careful that water does not enter the
master cylinder when refilling. Water will
significantly lower the boiling point of the
fluid and may result in vapor lock.
5. Brake fluid may deteriorate painted sur-
faces or plastic parts. Always clean up
spilled fluid immediately.
6. Have a Yamaha dealer check the cause if
the brake fluid level goes down.
