24. Once immediate safety hazards are con-
firmed not to exist, you may remove your hel-
met to more closely inspect your vehicle.
Check for external signs of wear, broken
parts, fluid leaks, cracks in the frame, suspen-
sion damage, wheel damage, and so on. Fuel,
oil, and coolant usually give off a noticeable
odor.
5. If your vehicle will not restart or if it is unsafe to ride, then turn off all vehicle systems (en-
gine stop switch, main switch, and fuel cock),
and then signal or go for help.
Aftermarket Parts, Accessories, and Modifica-
tions
While you may find aftermarket products similar in
design and quality to genuine Yamaha accesso-
ries, recognize that some aftermarket accessories
or modifications are not suitable because of poten-
tial safety hazards to you or others. Installing after-
market products or having other modifications
performed to your vehicle that change any of the
vehicle’s design or operation characteristics can
put you and others at greater risk of serious injury
or death. You are responsible for injuries related to changes in the vehicle. Keep the following guide-
lines in mind, as well as those provided under
“Loading” when mounting accessories.
●Never install accessories that would impair the
performance of your ATV. Carefully inspect the
accessory before using it to make sure that it
does not in any way reduce ground clearance,
limit suspension travel, steering travel or control
operation.●Accessories fitted to the ATV can create instabil-
ity due to improper weight distribution.●Bulky or large accessories may seriously affect
the stability of the ATV.●Certain accessories can displace the operator
from his or her normal riding position. This im-
proper position limits the freedom of movement
of the operator and may limit control ability,
therefore, such accessories are not recom-
mended.●Use caution when adding electrical accessories.
If electrical accessories exceed the capacity of
the ATV’s electrical system, an electric failure
could result, which could cause a dangerous
loss of lights or engine power.

4Adjust the spring preload as follows.
Turn the spring preload adjusting ring in direction
(a) to increase the spring preload and thereby
harden the suspension, and in direction (b) to de-
crease the spring preload and thereby soften the
suspension.
Align the appropriate notch in the adjusting ring
with the position indicator on the shock absorber.
TIPA special wrench can be obtained at a Yamaha
dealer to make this adjustment.

The figures quoted are emission levels and are not
necessarily safe working levels. Whilst there is a
correlation between the emission and exposure
levels, this cannot be used reliably to determine
whether or not further precautions are required.
Factors that influence the actual level of exposure
of work-force include the characteristics of the
work room, the other sources of noise, etc. i.e. the
number of machines and other adjacent process-
es, and the length of time for which an operator is
