Periodic inspection, adjustment and
lubrication will keep your motorcycle
in the safest and most efficient condi-
tion possible. Safety is an obligation
of the motorcycle owner. The mainte-
nance and lubrication schedule chart
should be considered strictly as a
guide to general maintenance and
lubrication intervals.
YOU MUST TAKE INTO CONSIDER-
ATION THAT WEATHER, TERRAIN,
GEOGRAPHICAL LOCATIONS, AND
A VARIETY OF INDIVIDUAL USES
ALL TEND TO DEMAND THAT
EACH OWNER ALTER THIS TIME
SCHEDULE TO SHORTER INTER-
VALS TO MATCH THE ENVIRON-
MENT. The most important points of
motorcycle inspection, adjustment,
and lubrication are explained in the
following pages.

Tool kitThe tool kit is located behind panel A.
(See page 6-7 for panel removal and
installation procedures.) The tools
provided in the owner's tool kit are to
assist you in the performance of peri-
odic maintenance. However, some
other tools such as a torque wrench
are also necessary to perform the
maintenance 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 preventive maintenance
and minor repairs.1.Tool kit

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.
The ideal color on the white insulator
around the center electrode is a
medium-to-light tan color for a motor-
cycle that is being ridden normally.
Do not attempt to diagnose such
problems yourself. Instead, take the
motorcycle to a Yamaha dealer. You
should periodically remove and
inspect the spark plug 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.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 tighten
it 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 cap.

Start the engine and keep it
idling until oil flows out of the
bleed hole. If no oil comes out
after one minute, turn off the
engine immediately so it will
not seize. In such a case go to
the nearest Yamaha dealer for
repairs.

After checking, tighten the air
bleed screw securely.

Drive chain lubricationThe chain consists of many parts
which work with each other. If the
chain is not maintained properly, it
will wear out quickly. Therefore, the
chain must be serviced regularly.
This service is especially necessary
when riding in dusty areas. This
motorcycle is equipped with a sealed
type chain. Steam cleaning, high-
pressure washers, and solvents can
damage the drive chain, so do not
use these for cleaning it. Use only
kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubricate it
with SAE 30 ~ 50W motor oil. Do not
use any other lubricants on the drive
chain. They may contain solvents
that could damage the sealed chain. Tightening torque:
Axle nut:
105 Nm (10.5 m
