This motorcycle must not be oper-
ated with the sidestand in the
down position. If the stand is not
properly retracted, it could contact
the ground and distract the opera-
tor, resulting in a possible loss of
control. Yamaha has designed into
this motorcycle a lockout system
to assist the operator in fulfilling
the responsibility of retracting the
sidestand. Please check carefully
the operating instructions listed
below and if there is any indication
of a malfunction, return the motor-
cycle to a Yamaha dealer immedi-
ately for repair.

Owners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to
deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements).
Any damage, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important
that, in addition to a thorough visual inspection, you check the following points before each ride.

5. Start the engine by pushing
the start switch.
NOTE:
If the engine fails to start, release
the start switch, wait a few sec-
onds, then try again. Each attempt
should be as short as possible to
preserve the battery. Do not crank
the engine more than 10 seconds
on any one attempt.
6. After starting the engine, move
the starter (choke) to the
halfway position.
NOTE:
For maximum engine life, never
accelerate hard with a cold engine!
7. After warming up the engine,
turn off the starter (choke)
completely.
NOTE:
The engine is warm when it
responds normally to the throttle
with the starter (choke) turned off.

EAU00629Carburetor adjustment
The carburetor is a vital part of the
engine and requires very sophisti-
cated adjustment. Most adjust-
ments should be left to a Yamaha
dealer who has the professional
knowledge and experience to do
so. However, the following may be
serviced by the owner as part of
routine maintenance.
EC000094
cC
The carburetor was set at the
Yamaha factory after many tests. If
the settings are changed, poor
engine performance and damage
may result.
EAU01168Idle speed adjustment
NOTE:
A diagnostic tachometer must be
used for this procedure.
1. Attach the tachometer. Start
the engine and warm it up for
a few minutes at approximate-
ly 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.

EAU00769Drive chain lubrication
The 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 regular-
ly. This service is especially neces-
sary when riding in dusty areas.
This motorcycle is equipped with a
sealed type chain. Steam cleaning,
high-pressure washes, and sol-
vents can damage chain so do not
use these for cleaning it. Use only
kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubri-
cate it with SAE 30 ~ 50W motor
oil. Do not use any other lubricants
on the drive chain. They may con-
tain solvents that could damage
the sealed chain.

MOTORCYCLE CARE AND STORAGE
7-1
Care
The exposure of its technology
makes a motorcycle charming but
also vulnerable. Although high-
quality components are used, they
are not all rust-resistant. While a
rusty exhaust pipe may remain
unnoticed on a car, it does look
unattractive on a motorcycle.
Frequent and proper care, howev-
er, will keep your motorcycle look-
ing good, extend its life and main-
tain its performance. Moreover, the
warranty states that the vehicle
must be properly taken care of. For
all these reasons, it is recommend-
ed that you observe the following
cleaning and storing precautions.
Before cleaning
1. Cover up the muffler outlets
with plastic bags.
2. Make sure that all caps and
covers as well as all electrical
couplers and connectors,
including the spark plug caps,
are tightly installed.
3. Remove extremely stubborn
dirt, like oil burnt onto the
crankcase, with a degreasing
agent and a brush, but never
apply such products onto
seals, gaskets, sprockets, the
drive chain and wheel axles.
Always rinse the dirt and
degreaser off with water.Cleaning
After normal use
Remove dirt with warm water, a
neutral detergent and a soft clean
sponge, then rinse with plenty of
clean water. Use a tooth or bottle
brush for hard-to-reach parts.
Tougher dirt and insects will come
off more easily if the area is cov-
ered with a wet cloth for a few
minutes before cleaning.
ECA00010
cC
8Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If you do use
such products for hard-to-
remove dirt, do not leave it on
any longer than instructed,
then thoroughly rinse it off
with water, immediately dry
the area and apply a corrosion
protection spray.
