1. Spark plug wrench
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 elec-
trode. The ideal color at this point is a
medium-to-light tan color for a motor-
cycle that is being ridden normally. If
one spark plug shows a distinctly dif-
ferent 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 periodi-cally 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 excessive, or if carbon and
other deposits are excessive, you
should replace the spark plug with the
specified plug.
Specified spark plug:
DPR7EA-9 (NGK)
X22EPR-U9 (DENSO)
a. Spark plug gap
Installation
1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.
2. Clean the gasket surface. Wipe
off any grime from the threads.
3. Install the spark plug and tighten it
to the specified torque. Spark plug gap:
0.8 ~ 0.9 mm

NOTE:

If a torque wrench is not available
when you are installing a spark plug, a
good estimate of the correct torque is
1/4 to 1/2 turn past finger tight. Have
the spark plug tightened to the speci-
fied torque as soon as possible.Tightening torque:
Spark plug:
20 Nm (2.0 m·kg)

Engine oil
Oil level inspection
1. Place the motorcycle on a level
place and hold it in an upright po-
sition. Warm up the engine for
several minutes.
NOTE:

Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings.
1. Engine oil drain bolt
2. With the engine stopped, check
the oil level through the level win-
dow located at the lower part of
the left side crankcase cover.
NOTE:

Wait a few minutes until the oil level
settles before checking.
3. The oil level should be between
the maximum and minimum
marks. If the level is low, fill the
engine with sufficient oil to the
specified level.

CAUTION:

l
Do not put in any chemical ad-
ditives. Engine oil also lubri-
cates the clutch and additives
could cause clutch slippage.
l
Be sure no foreign material en-
ters the crankcase.
10. Start the engine and warm it up
for a few minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.

get on the tire or wheel.
Oil level inspection
1. Place the motorcycle on a level
place and hold it in an upright po-
sition. The engine should be cool
at ambient temperature.2. Remove the oil filler bolt and
check the oil level. The oil level
should be at the brim of the filler
hole. Add the recommended oil if
necessary.
Oil replacement
1. Place an oil pan under the final
gear case.
2. Remove the oil filler bolt and drain
bolt to drain the oil.

Air filterThe air filter should be cleaned at the
specified intervals. It should be
cleaned more frequently if you are
riding in unusually wet or dusty areas.
1. Remove the air filter case cover
by removing the screws.
2. Remove the air filter.
3. Tap the air filter lightly to remove
most of the dust and dirt. Blow out
the remaining dirt with com-
pressed air as shown. If the air fil-
ter is damaged, replace it.

CAUTION:l
Make sure the air filter is prop-
erly seated in the air filter case.
l
The engine should never be run
without the air filter installed.
Excessive piston and/or cylin-der wear may result.
EAU00630
Carburetor adjustmentThe carburetors are important parts of
the engine and require very sophisti-
cated adjustment. Most adjustments
should be left to a Yamaha dealer who
has the professional knowledge and
experience to do so. However, the idle
speed may be adjusted by the owner
as part of routine maintenance.
EC000095
CAUTION:
The carburetors were set at the
Yamaha factory after many tests. If
they are changed, poor engine per-formance and damage may result.
