Adjusting the valve
clearanceThe valve clearance changes with
use, resulting in improper air-fuel mix-
ture and/or engine noise. To prevent
this from occurring, the valve clear-
ance must be adjusted by a Yamaha
dealer at the intervals specified in the
periodic maintenance and lubrication
chart.

TiresTo maximize the performance, dura-
bility, and safe operation of your
motorcycle, note the following points
regarding the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EW000082
w8The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the
ambient temperature).
8The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passen-
ger, cargo, and accessories
approved for this model.

TroubleshootingAlthough Yamaha motorcycles
receive a thorough inspection before
shipment from the factory, trouble
may occur during operation. Any
problem in the fuel, compression, or
ignition systems, for example, can
cause poor starting and loss of
power.
The following troubleshooting chart
represents a quick and easy proce-
dure for checking these vital systems
yourself. However, should your
motorcycle require any repair, take it
to a Yamaha dealer, whose skilled
technicians have the necessary tools,
experience, and know-how to service
the motorcycle properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life
and can lead to expensive repair
bills.

MOTORCYCLE CARE AND STORAGE
8Do 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 abra-
sive cleaning products, sol-
vent or thinner, fuel (gasoline),
rust removers or inhibitors,
brake fluid, antifreeze or elec-
trolyte.
8Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel and swingarm bearings,
fork and brakes), electric com-
ponents (couplers, connec-
tors, instruments, switches
and lights), breather hoses
and vents.8For motorcycles equipped
with a windshield: Do not use
strong cleaners or hard
sponges as they will cause
dulling or scratching. Some
cleaning compounds for plas-
tic may leave scratches on the
windshield. Test the product
on a small hidden part of the
windshield to make sure that it
does not leave any marks. If
the windshield is scratched,
use a quality plastic polishing
compound after washing.
After normal useRemove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottle-
brush for hard-to-reach areas.
Stubborn dirt and insects will come
off more easily if the area is covered
with a wet cloth for a few minutes
before cleaning.After riding in the rain, near the sea
or on salt-sprayed roadsSince sea salt or salt sprayed on
roads during winter are extremely
corrosive in combination with water,
carry out the following steps after
each ride in the rain, near the sea or
on salt-sprayed roads.NOTE:
Salt sprayed on roads in the winter
may remain well into spring.1.Clean the motorcycle with cold
water and a mild detergent, after
the engine has cooled down.
ECA00012
cCDo not use warm water since it
increases the corrosive action of
the salt.2.After drying the motorcycle,
apply a corrosion protection
spray on all metal, including
chrome- and nickel-plated, sur-
faces to prevent corrosion.

MOTORCYCLE CARE AND STORAGE

7-4
StorageShort-term
Always store your motorcycle in a
cool, dry place and, if necessary, pro-
tect it against dust with a porous
cover.
ECA00014
cC8Storing the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp, while it is
still wet, will allow water and
humidity to seep in and cause
rust.
8To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
Long-term
Before storing your motorcycle for
several months:
1.Follow all the instructions in the
ÒCareÓ section of this chapter.
2.Turn the fuel cock lever to ÒONÓ.
3.Drain the carburetor float cham-
bers by loosening the drain bolts;
this will prevent fuel deposits
from building up. Pour the
drained fuel into the fuel tank.
4.Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5.Perform the following steps to
protect the cylinders, piston
rings, etc. from corrosion.
a.Remove the spark plug caps
and spark plugs.
b.Pour a teaspoonful of engine
oil into each spark plug bore.c.Install the spark plug caps
onto the spark plugs, and then
place the spark plugs on the
cylinder head so that the elec-
trodes are grounded. (This will
limit sparking during the next
step.)
d.Turn the engine over several
times with the starter. (This
will coat the cylinder walls with
oil.)
e.Remove the spark plug caps
from the spark plugs, and then
install the spark plugs and the
spark plug caps.
EWA00003
wTo prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turn-
ing the engine over.6.Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.

cCBe sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled ÒEnergy
ConservingÓ) contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting in reduced
component life and poor engine performance.
