WARNING
@ Always adjust each shock absorber
to the same setting. Uneven adjust-
ment can cause poor handling and
loss of stability. @
EAU00316
WARNING
@ These shock absorbers contain
highly pressurized nitrogen gas.
Read and understand the following
information before handling the
shock absorbers. The manufacturer
cannot be held responsible for prop-
erty damage or personal injury that
may result from improper handling.l
Do not tamper with or attempt to
open the cylinder assemblies.
l
Do not subject the shock ab-
sorbers to an open flame or oth-
er high heat source. This may
cause the unit to explode due to
excessive gas pressure.
l
Do not deform or damage the
cylinders in any way. Cylinder
damage will result in poor
damping performance.
l
Take your shock absorbers to a
Yamaha dealer for any service.

4-PRE-OPERATION CHECKSOwners 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 in-
spection, you check the following points before each ride.
EAU00340
PRE-OPERATION CHECK LIST
ITEM CHECKS PAGE
Front brake
• Check operation, fluid level and vehicle for fluid leakage.
• Fill with DOT 4 brake fluid if necessary.6-16 ~ 6-19

OPERATION AND IMPORTANT RIDING POINTS
5-3
51. Turn the fuel cock to “ON”.
2. Turn the main switch to “ON” and
the engine stop switch to “ ”.
3. Shift transmission into neutral.
NOTE:@ When the transmission is in neutral, the
neutral indicator light should be on. If
the light does not come on, ask a
Yamaha dealer to inspect it. @4. Turn on the starter (choke) and
completely close the throttle grip.
5. Start the engine by pushing the
start switch.NOTE:@ If the engine fails to start, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one attempt. @
EC000034
CAUTION:@ The oil level indicator light should
come on when the start switch is
pushed and should go off when the
start switch is released. If the indica-
tor light flickers or remains on, im-
mediately stop the engine and
check the engine oil level and for oil
leakage. If necessary, fill the engine
with oil and check to see that the oil
level indicator light goes off. If the
light does not go off even with suffi-
cient oil in the crankcase or the light
does not come on when pushing the
start switch, consult a Yamaha deal-
er. @6. After starting the engine, move the
starter (choke) halfway back.NOTE:@ For maximum engine life, never accel-
erate hard with a cold engine! @
7. After the engine is warm, turn off
the starter (choke) completely.NOTE:@ The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off. @
PERIODIC MAINTENANCE AND MINOR REPAIR
6-11
65. Tap the air filter lightly to remove
most of the dust and dirt and blow
out the remaining dirt with com-
pressed air as shown. If the air fil-
ter is damaged, replace it.
6. Reassemble by reversing the re-
moval procedure.
EC000082
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.

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.

CAUTION:@ l
Avoid 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 long-
er than instructed, then thor-
oughly rinse it off with water,
immediately dry the area and
apply a corrosion protection
spray.
l
Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent and
water to clean plastic.
l
Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake flu-
id, antifreeze or electrolyte.
l
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel bearings,
swingarm bearings, forks and
brakes), electric components
(couplers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
l
For motorcycles equipped with
a windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning
compounds for plastic may
leave scratches on the wind-
shield. Test the product on a
small hidden part of the wind-
shield to make sure they do not
leave any marks. If the wind-
shield is scratched, use a quali-
ty plastic polishing compound
after washing.
@After riding in the rain, near the sea oron salt-sprayed roadsSince sea salt or salt sprayed on the
roads in the winter are extremely corro-
sive in combination with water, carry
out the following steps after each ride
in the rain, near the sea or on salt-
sprayed roads. (Salt sprayed in the
winter may remain on the roads well
into spring.)
