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.

6 Tire inspection
Always check the tires before operating
the motorcycle. If center tread depth
reaches the limit as shown, if the tire
has a nail or glass fragments in it, or if
the side wall is cracked, contact a
Yamaha dealer immediately and have
the tire replaced.
CE-10E
CE-11ENOTE:@ These limits may be different by regula-
tion from country to country. If so, con-
form to the limits specified by the
regulations of your own country. @
EAU00681
WARNING
@ l
Operating the motorcycle with
excessively worn tires decrease
riding stability and can lead to
loss of control. Have excessive-
ly worn tires replaced by a
Yamaha dealer immediately.
Brakes, tires, and related wheel
parts replacement should be
left to a Yamaha Service Techni-
cian.
l
Patching a punctured tube is
not recommended. If it is abso-
lutely necessary to do so, use
great care and replace the tube
as soon as possible with a good
quality replacement.

WheelsTo ensure maximum performance,
long service, and safe operation, note
the following:l
Always inspect the wheels before
a ride. Check for cracks, bends or
warpage of the wheel. Be sure the
spokes are tight and undamaged.
If any abnormal condition exists in
a wheel, consult a Yamaha dealer.
Do not attempt even small repairs
to the wheel. If a wheel is de-
formed or cracked, it must be re-
placed.
l
Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse han-
dling characteristics, and short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.

Clutch lever free play
adjustmentThe clutch lever free play should be ad-
justed to 10 ~ 15 mm.

ver.
2. Turn the adjusting bolt at the
clutch lever in direction

Drive belt slack check1. Put the motorcycle on the side-
stand and make sure that both
wheels are on the ground.
2. Using the reference marks at the
side of the check window, which is
located at the rear left side of the
motorcycle, note the current posi-
tion of the drive belt.3. Apply a force of 45 N (4.5 kg) with
the belt tension gauge to the lower
drive belt run as shown and re-
check the drive belt position in the
check window. The normal drive
belt slack (i.e., the distance be-
tween the original belt position and
its position with the force applied)
is approximately 7.5 ~ 13 mm.
4. If the measured slack exceeds
13 mm, adjust the drive belt.
NOTE:@ The reference marks at the side of the
drive belt check window are 5 mm
apart. @
