TiresTo ensure maximum performance,
long service and safe operation, note
the following:
Tire air pressure
Always check and adjust the tire
pressure before operating the motor-
cycle.
EW000082
wTire 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
according to total weight of cargo,
rider, passenger, and accessories
(fairing, saddlebags, etc. if
approved for this model), and vehi-
cle speed.
EAU00637
Valve clearance adjustmentThe 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 profes-
sional Yamaha service technician.

Drive chain lubricationThe 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 regularly.
This service is especially necessary
when riding in dusty areas. This
motorcycle is equipped with a sealed
type chain. Steam cleaning, high-
pressure washers, and solvents can
damage the drive chain, so do not
use these for cleaning it. Use only
kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubricate it
with SAE 30 ~ 50W motor oil. Do not
use any other lubricants on the drive
chain. They may contain solvents
that could damage the sealed chain. Tightening torque:
Axle nut:
105 Nm (10.5 m
0kg)
Caliper bracket bolt:
48 Nm (4.8 m
0kg)

2.Turn both left and right chain
adjusting plates the same
amount. Make sure that they are
in the same position for proper
wheel alignment. To tighten the
chain, turn in direction a. To
loosen the chain, turn in direction

Throttle cable and grip
lubricationThe throttle twist grip assembly
should be greased at the time that
the cable is lubricated, since the grip
must be removed to get at the end of
the throttle cable. After removing the
screws, hold the end of the cable up
in the air and put in several drops of
lubricant. With the throttle grip disas-
sembled, coat the metal surface of
the grip assembly with a suitable all-
purpose grease.

wDamage to the outer housing of
cables may lead to internal rusting
and interfere with the cable move-

soon as possible to prevent unsafe
conditions.Lubricate the cables and cable ends.
If a cable does not operate smoothly,
ask a Yamaha dealer to replace it.

Wheel bearingsIf there is play in the front or rear
wheel hub or if the wheel does not
turn smoothly, have a Yamaha dealer
inspect the wheel bearings.
EAU00794
Steering inspectionPeriodically inspect the condition of
the steering. Worn out or loose steer-
ing bearings may be dangerous.
Place a stand under the engine to
raise the front wheel off the ground.
Hold the lower end of the front forks
and try to move them forward and
backward. If any free play can be felt,
ask a Yamaha dealer to inspect and
adjust the steering. Inspection is eas-
ier if the front wheel is removed.

Supporting the motorcycleSince the Yamaha XT500E/XT600E
has no centerstand, follow these pre-
cautions when removing the front and
rear wheel or performing other main-
tenance requiring the motorcycle to
stand upright. Check that the motor-
cycle is in a stable and level position
before starting any maintenance. A
strong wooden box can be placed
under the engine for added stability.
Front wheel service
To stabilize the rear of the motorcy-
cle, either use a motorcycle stand or
place a motorcycle jack under the
frame in front of the rear wheel to
prevent it from moving from side to
side. Then use a motorcycle stand to
elevate the front wheel off of the
ground.
