CAUTION:_ Never turn an adjusting mechanism beyond
the minimum and maximum settings. _NOTE:_ Although the total number of clicks of a damping
force adjusting mechanism may not exactly match
the above specifications due to small differences in
production, the actual number of clicks always repre-
sents the entire adjusting range. To obtain a precise
adjustment, it would be advisable to check the num-
ber of clicks of each damping force adjusting mech-
anism and to modify the specifications as necessary. _
WARNING
_ Suspension components become hot during
operation. Never touch the compression
damping adjuster, rebound damping adjuster
or oil reservoir with your bare hand or skin un-
til suspension components have cooled. _
From the fully turned-out position
Minimum (soft): 1 click in
Standard: 7 clicks in
Maximum (hard): 12 clicks in

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 intervals
specified in the periodic maintenance and lubrica-
tion chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Start the engine, warm it up until the engine
oil has reached a normal temperature 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 with a clean rag, 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 engine oil drain bolt.
5. Remove the engine oil tank filler cap and the
oil tank drain bolt.
6. Check the washers for damage, and replace
if necessary.NOTE:_ Skip steps 7 ~ 8 if the oil filter cartridge is not being
replaced. _

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

Observe these precautions:

When checking the fluid level, make sure the
top of the brake fluid reservoir is level.


Use only the designated quality brake fluid.
Otherwise, the rubber seals may deteriorate,
causing leakage and poor brake performance.


Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor brake performance.


Be careful that water does not enter the brake
fluid reservoir when refilling. Water will signifi-
cantly lower the boiling point of the fluid and
may result in vapor lock.


Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.


Have a Yamaha dealer check the cause if the
brake fluid level goes down. Recommended brake fluid: DOT 4
