er’s weight and the riding conditions.
WARNING
EWB00401Always adjust the shock absorber assemblies
on the left and right side to the same setting.
Uneven adjustment can cause poor handling
and loss of stability, which could lead to an ac-
cident. Adjust 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. 1. Spring preload adjusting ring

EBU39831Owner’s Manuals and Tool KitBe sure to always keep this manual, the Winch
Owner’s Manual, the tool kit and the low-pressure
tire gauge with the vehicle. Make sure to protect
the owner’s manuals by putting them in a plastic
bag, and then placing the bag in the document
pouch.
The information included in this manual and the
tools provided in the tool kit are intended to assist
you in the performance of preventive maintenanceand minor repairs. However, additional tools such
as a torque wrench are necessary to perform cer-
tain maintenance work correctly.
TIPIf you do not have the tools or experience required
for a particular job, have a Yamaha dealer perform
it for you.

EBU38132Checking the spark plugThe spark plug is an important engine component,
which is easy to check. Since heat and deposits
will cause any spark plug to slowly erode, the
spark plug should be removed and checked in ac-
cordance with the periodic maintenance chart. In
addition, the condition of the spark plug can reveal
the condition of the engine.
To remove the spark plug1. Remove panels A, C and E. (See page 9-10.)
2. Remove the spark plug cap. 3. Remove the spark plug as shown, with the
spark plug wrench included in the tool kit.
Tightening torques:
Panel bolt:4.0 N·m (0.40 kgf·m, 3.0 lb·ft)

9To check the spark plug
1. Check that the porcelain insulator around the center electrode of the spark plug is a medi-
um-to-light tan (the ideal color when the vehi-
cle is ridden normally).
TIPIf the spark plug shows a distinctly different color,
the engine could be operating improperly. Do not
attempt to diagnose such problems yourself. In-
stead, have a Yamaha dealer check the vehicle. 2. Check the spark plug for electrode erosionand excessive carbon or other deposits, and
replace it if necessary.
3. Measure the spark plug gap with a wire thick- ness gauge and, if necessary, adjust the gap
to specification. To install the spark plug
1. Clean the surface of the spark plug gasket and its mating surface, and then wipe off any
grime from the spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tighten it to the specified
torque.
Specified spark plug:

TIPIf a torque wrench is not available when installing
the spark plug, a good estimate of the correct
torque is 1/4–1/2 turn past finger tight. However,
the spark plug should be tightened to the speci-
fied torque as soon as possible. 3. Install the spark plug cap.
4. Install the panels.EBU2746DEngine oil and oil filter cartridgeThe 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 chart.
To check the engine oil level1. Park the ATV on a level surface.
2. Check the engine oil level on a cold engine.
TIPIf the engine was started before checking the oil
level, warm up the engine, and then wait at least
10 minutes until the oil settles for an accurate
reading. 3. Remove the access cover by turning it coun- terclockwise.
4. Remove the engine oil dipstick, and then wipe it off with a clean rag.
Tightening torque:
Spark plug:13 N

To change the engine oil (with or without oil fil-
ter cartridge replacement)
1. Park the ATV on a level surface.
2. Start the engine, warm it up for several minu- tes, and then turn it off.
3. Remove the access cover by turning it coun- terclockwise.
4. Place an oil pan under the engine to collect the used oil.
5. Remove the dipstick, and then remove the engine oil drain bolt and its gasket to drain the
oil from the crankcase.
TIPSkip steps 6–10 if the oil filter cartridge is not be-
ing replaced. 6. Remove panel F. (See page 9-10.)
7. Remove the oil filter cartridge with an oil filterwrench.TIPAn oil filter wrench is available at a nearby Yamaha
dealer. 8. Apply a thin coat of engine oil to the O-ring ofthe new oil filter cartridge.
