Inspection
The spark plug is an important engine
component and is easy to inspect.
The condition of the spark plug can
indicate the condition of the engine.
Normally, all spark plugs from the
same engine should have the same
color on the white insulator around
the center electrode. The ideal color
at this point is a medium-to-light tan
color for a motorcycle that is being
ridden normally. If one spark plug
shows a distinctly different color,
there could be something wrong with
the engine.
Do not attempt to diagnose such
problems yourself. Instead, take the
motorcycle to a Yamaha dealer. You
should periodically remove and
inspect the spark plugs because heat
and deposits will cause any spark
plug to slowly break down and erode.
If electrode erosion becomes exces-
sive, or if carbon and other deposits
are excessive, you should replace the
spark plug with the specified plug.
Specified spark plug:
CR6HSA (NGK) or
U20FSR-U (DENSO)

EAU01523Engine oil
Oil level inspection
1. Place the motorcycle on a level
place and hold it in an upright
position. Warm up the engine
for several minutes.
NOTE:
Be sure the motorcycle is posi-
tioned straight up when checking
the oil level. A slight tilt toward the
side can result in false readings.

Installation
1. Measure the electrode gap
with a wire thickness gauge
and, if necessary, adjust the
gap to specification.
2. Clean the gasket surface. Wipe
off any grime from the
threads.
3. Install the spark plug and tight-
en it to the specified torque.
a. Spark plug gap
NOTE:
If a torque wrench is not available
when you are installing a spark
plug, a good estimate of the cor-
rect torque is 1/4 to 1/2 turn past
finger tight. Have the spark plug
tightened to the specified torque as
soon as possible.
4. Install the spark plug caps.
Spark plug gap:
0.6 ~ 0.7 mm
Tightening torque:
Spark plug:
12.5 Nm (1.25 m0kg)

2. With the engine stopped,
check the oil level through the
level window located at the
lower part of the right side
crankcase cover.
NOTE:
Wait a few minutes until the oil
level settles before checking.
3. The oil level should be
between maximum level and
minimum level marks. If the
level is low, fill engine with
sufficient oil to raise it to the
specified level.

8Do not put in any chemical
additives. Engine oil also lubri-
cates the clutch and additives
could cause clutch slippage.
8Be sure no foreign material
enters the crankcase.
9. Start the engine and warm up
for a few minutes. While
warming up, check for oil leak-
age. If oil leakage is found,
stop the engine immediately
and check for the cause.
10. Stop the engine and check the
oil level. Recommended oil:
See page 8-1.
Oil quantity:
Total amount:
1.7 L
Periodic oil change:
1.4 L
With oil filter replacement:
