vals. However, keep in mind that if the ATV isn’t used for a long period of time, the month maintenance
intervals should be followed.●Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools,

EBU23080Removing and installing the panel The panel shown needs to be removed to perform
some of the maintenance jobs described in this
chapter. Refer to this section each time the panel
needs to be removed and installed.EBU23101Panel A
To remove the panelRemove the bolts, and then take the panel off.To install the panel
Place the panel in the original position and install
the bolts.EBU23213Checking the spark plug The 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 accor-
dance with the periodic maintenance and lubrica-
tion chart. In addition, the condition of the spark
plug can reveal the condition of the engine.

To remove the spark plug
1. Remove the spark plug cap.
2. Remove the spark plug as shown, with the spark plug wrench included in the owner’s tool
kit. To 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 ATV
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 ATV.

EBU26786Engine oil and oil filter element The engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter element replaced at the intervals spec-
ified in the periodic maintenance and lubrication
chart.
To check the engine oil level1. 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
(140 °F), let it continue to idle for ten seconds
or more, and then turn the engine off.TIPTo 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 tem-
perature.3. Remove the engine oil tank filler cap, and thenwipe the engine oil dipstick off with a clean
rag.
4. Insert the dipstick in the filler hole (without screwing it in), and then remove 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 the minimumlevel mark, add sufficient oil of the recom-
mended type through the engine oil tank filler
hole to raise it to the correct level. NOTICE:1. Engine oil tank

8Be sure the engine oil is at the correct lev-
el, otherwise engine damage may result.
[ECB00851]
TIPWhen adding oil, be careful not to overfill the en-
gine oil tank; the oil level rises faster starting from
the half-level-portion on the dipstick.6. Insert the dipstick into the engine oil tank filler
hole, and then tighten the engine oil tank filler
cap. NOTICE: Make sure that the engine oil
tank filler cap is securely tightened; other-
wise, oil may seep out when the engine is
running.
[ECB00362]
To change the engine oil (with or without oil fil-
ter element replacement) 1. Place the ATV on a level surface.
2. Start the engine, warm it up for several min- utes, and then turn it off.
3. Place an oil pan under the engine to collect the used oil.
4. Remove the crankcase engine oil filler cap and its O-ring, and then remove the crank-
case engine oil drain bolt and its gasket.

fied torque. 10. Install the crankcase engine oil drain bolt, the
engine oil tank drain bolt and their new gasket,
and then tighten the bolts to the specified
torques.
11. Install the crankcase engine oil filler cap and its new O-ring, and then tighten the oil filler
cap to the specified torque.
12. Pour only 1.3 L (1.37 US qt, 1.14 Imp.qt) of the specified amount of the recommended en-
gine oil through the engine oil tank filler hole,
and then install and tighten the oil tank filler
cap.
