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.

WARNING
@ If you are not familiar with motor-
cycle service, this work should be
done by a Yamaha dealer. @
EAU01299
Tool kitThe tool kit is located inside the storage
compartment under the seat. (See
page 3-12 for seat opening proce-
dures.) The tools provided in the own-
er’s tool kit are to assist you in the
performance of periodic 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 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. @
EW000063
WARNING
@ Modifications to this motorcycle not
approved by Yamaha may cause
loss of performance, and render it
unsafe for use. Consult a Yamaha
dealer before attempting any chang-
es. @

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. @
EAU00632
Idle speed adjustment1. Start the engine and warm it up for
a few minutes at approximately
1,000 to 2,000 r/min. Occasionally
rev the engine to 4,000 to
5,000 r/min. The engine is warm
when it quickly responds to the
throttle.
2. Set the idle to the specified engine
speed by adjusting the throttle
stop screw. Turn the screw in di-
rection
a to increase engine
speed and in direction
b to de-
crease engine speed.1. Throttle stop screw
