This motorcycle must not be oper-
ated with the sidestand in the
down position. If the stand is not
properly retracted, it could contact
the ground and distract the opera-
tor, resulting in a possible loss of
control. Yamaha has designed into
this motorcycle a lockout system
to assist the operator in fulfilling
the responsibility of retracting the
sidestand. Please check carefully
the operating instructions listed
below and if there is any indication
of a malfunction, return the motor-
cycle to a Yamaha dealer immedi-
ately for repair.

9Owners 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 inspection, you check the following points before each ride.

1. Before riding this motorcycle,
become thoroughly familiar
with all operating controls and
their functions. Consult a
Yamaha dealer regarding any
control or function that you do
not thoroughly understand.
2. Never start your engine or let
it run for any length of time in
a closed area. The exhaust
fumes are poisonous and can
cause loss of consciousness
and death within a short time.
Always operate your motorcy-
cle in an area with adequate
ventilation.
3. Before starting out, always be
sure the sidestand is up.
Failure to retract the sidestand
completely can result in a seri-
ous accident when you try to
turn a corner.
EAU00411
Starting and warming up a
cold engine
NOTE:
This motorcycle is equipped with a
starting and an ignition circuit cut-
off switch.
1. The engine can be started only
under the following condi-
tions:
a. The transmission is in neutral.
b. The sidestand is up, the trans-
mission is in gear, and the
clutch is disengaged.
2. The motorcycle must not be
ridden when the sidestand is
down.

Before going through the follow-
ing steps, check the function of the
sidestand switch and clutch
switch. (Refer to page 3-11.)

6 break down and erode. If electrode
erosion becomes excessive, or if
carbon and other deposits are
excessive, you should replace the
spark plug with the specified plug.
Before installing the spark plug,
measure the electrode gap with a
wire thickness gauge; adjust the
gap to specification as necessary.
When installing the plug, always
clean the gasket surface and use a
new gasket. Wipe off any grime
from the threads and tighten the
spark plug to the specified torque.Specified spark plug:
DR8EA (NGK) or
X24ESR-U (DENSO)Spark plug gap:
0.6 ~ 0.7 mm
Tightening torque:
Spark plug:
17.5 Nm (1.75 m0kg)
NOTE:
If a torque wrench is not available
when you are installing a spark
plug, a good estimate of the cor-
rect torque is 1/4 to 1/2 turn past
finger tight. Have the spark plug
tightened to the specified torque as
soon as possible.EAU00517Engine oil
1. Oil level measurement
a. Place the motorcycle on a level
place and hold it in an upright
position. Warm up the engine
for several minutes.
NOTE:
Be sure the motorcycle is posi-
tioned straight up when checking
the oil level. A slight tilt toward the
side can result in false readings.

b. With the engine stopped,
check the oil level through the
level window located at the
lower part of the right side
crankcase cover.
NOTE:
Wait a few minutes until the oil
level settles before checking.
c. The oil level should be
between the maximum and
minimum marks. If the level is
low, add sufficient oil to raise
it to the proper level.

additives. Engine oil also lubri-
cates the clutch and additives
could cause clutch slippage.
8Be sure no foreign material
enters the crankcase.

for a few minutes. While
warming up, check for oil leak-
age. If oil leakage is found,
stop the engine immediately
and check for the cause.

9 To check the chain slack the motor-
cycle must be held straight up with
both wheels on the ground and
without rider. Check the slack at
the position shown in the illustra-
tion. Normal slack is approximately
30 ~ 40 mm. If the slack exceeds 40
mm, adjust.

Drive chain slack adjustment
1. Loosen the rear brake adjust-
ing nut.
2. Remove the cotter pin from
the axle nut.
3. Loosen the axle nut.
4. Turn both left and right chain
adjusting plates the same
amount. Make sure that they
are in the same position for
proper wheel alignment.

Too little chain slack will overload
the engine and other vital parts.
Keep the slack within the specified
limits.
