Valve clearance adjustment
The correct valve clearance changes
with use, resulting in improper fuel/air
supply or engine noise. To prevent this,
the valve clearance must be adjusted
regularly. This adjustment however,
should be left to a professional
Yamaha service technician.

Tires
To ensure maximum performance,
long service, and safe operation, note
the following:
Tire air pressure
Always check and adjust the tire pres-
sure before operating the motorcycle.
EW000082
Tire inflation pressure should be
checked and adjusted when the
temperature of the tire equals the
ambient air temperature. Tire infla-
tion pressure must be adjusted ac-
cording to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if approved
for this model), and vehicle speed.

sert the axle.
2. Install and adjust the drive chain.
(See page 6-20 for details about
adjusting the drive chain slack.)
3. Install the axle nut.
4. Install the caliper and caliper bolts.
Make sure there is enough gap
between the brake pads before in-
stalling the caliper onto the brake
disc.
5. Take the motorcycle off the cen-
terstand.
6. Tighten the axle nut and brake
torque rod bolt to the specified
torques.
Tightening torque:
Axle nut:
105 Nm (10.5 mákg)
Brake torque rod bolt:
23 Nm (2.3 mákg)

Troubleshooting
Although Yamaha motorcycles receive
a rigid inspection before shipment from
the factory, trouble may occur during
operation.
Any problem in the fuel, compression,
or ignition systems can cause poor
starting and loss of power. The trouble-
shooting chart describes a quick, easy
procedure for making checks.
If your motorcycle requires any repair,
bring it to a Yamaha dealer. The skilled
technicians at a Yamaha dealership
have the tools, experience, and know-
how to properly service your motor-
cycle. Use only genuine Yamaha parts
on your motorcycle. Imitation parts may
look like Yamaha parts, but they are of-
ten inferior. Consequently, they have a
shorter service life and can lead to ex-
pensive repair bills.

MOTORCYCLE CARE AND STORAGE
/Net/layout8/layout_G2/work/Imai_work/OM-PS/AA9156_XJ600SN-E6/English/E-7.frame
ECA00010
CAUTION:
lAvoid 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.
lImproper 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.
lDo 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.
lDo 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.
lFor 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 or
on salt-sprayed roads
Since 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.)

CAUTION:
lApply spray oil and wax spar-
ingly and wipe off any excess.
lNever apply oil or wax on rub-
ber and plastic parts, but treat
them with a suitable care prod-
uct.
lAvoid using abrasive polishing
compounds as they wear away
the paint.
NOTE:
Consult a Yamaha dealer for advice on
what products to use.
Storage
Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA00014
CAUTION:
lStoring the motorcycle in a
poorly ventilated room or cov-
ering it with a tarp while it is still
wet will allow water and humidi-
ty to seep in and cause rust.
lTo 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 sev-
eral months:
1. Follow all the instructions in the
ÒCareÓ section of this chapter.
2. 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.
3. Only for motorcycles equipped
with a fuel cock which has an
ÒOFFÓ position: Turn the fuel cock
to ÒOFFÓ.
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 pro-
tect 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.

CAUTION:
Be 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.
