6-PERIODIC MAINTENANCE AND MINOR REPAIR
EAU00464
Periodic inspection, adjustment and lu-
brication will keep your motorcycle in
the safest and most efficient condition
possible. Safety is an obligation of the
motorcycle owner. The maintenance
and lubrication schedule chart should
be considered strictly as a guide to
general maintenance and lubrication
intervals. YOU MUST TAKE INTO
CONSIDERATION THAT WEATHER,
TERRAIN, GEOGRAPHICAL LOCA-
TIONS, AND A VARIETY OF INDIVID-
UAL USES ALL TEND TO DEMAND
THAT EACH OWNER ALTER THIS
TIME SCHEDULE TO SHORTER IN-
TERVALS TO MATCH THE ENVI-
RONMENT. The most important points
of motorcycle inspection, adjustment,
and lubrication are explained in the fol-
lowing pages.

@ If you are not familiar with motor-
cycle service, this work should be
done by a Yamaha dealer. @

Tool kitThe tool kit is located inside the storage
compartment. (See page 3-11 for com-
partment opening procedures.) The
tools provided in the owner’s tool kit are
to assist you in the performance of pe-
riodic maintenance. However, some
other tools such as a torque wrench are
also necessary to perform the mainte-
nance correctly.
The service information included in this
manual is intended to provide you, the
owner, with the necessary information
for completing some of your own pre-
ventive maintenance and minor re-
pairs.
NOTE:@ If you do not have necessary tools re-
quired during a service operation, take
your motorcycle to a Yamaha dealer for
service. @

1. Measure the electrode gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifica-
tion.
2. Clean the gasket surface. Wipe off
any grime from the threads.
3. Install the spark plugs and tighten
to the specified torque.
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 specified
torque as soon as possible. @4. Install the spark plug caps and the
cylinder head covers.

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 en-
gine with sufficient oil to the speci-
fied level.Engine oil replacement
1. Warm up the engine for a few min-
utes.
2. Stop the engine. Place an oil pan
under the engine and remove the
oil filler cap.
3. Remove the drain bolt and drain
the oil.
4. Reinstall the drain bolt and tighten
it to the specified torque.5. Fill the engine with sufficient rec-
ommended oil. Install the oil filler
cap and tighten it.

CAUTION:@ l
Do not put in any chemical addi-
tives. Engine oil also lubricates
the clutch and additives could
cause clutch slippage.

indicator light should go off if oil is filled
to the specified level. @

WARNING
@ Do not let foreign material enter the
final gear case. Be sure oil does not
get on the tire or wheel. @Oil level inspection
1. Place the motorcycle on a level
place and hold it in an upright posi-
tion. 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
