Si destan d
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See the following section for an
explanation of the ignition circuit cut-
off system.)
WARNING
EWA10242
The vehicle must not  be ri dden with
the si destan d d own, or if the si de-
stan d cannot b e properly move d up
(or  does not stay up), otherwise the
si destan d coul d contact the  groun d
an d d istract the operator, resultin g
in a possib le loss of control.
Yamaha’s ig nition circuit cut-off
system has  been  desi gne d to assist
the operator in fulfillin g the respon-
si bility of raisin g the si destan d b e-
fore startin g off. Therefore, check
this system re gularly an d have a
Yamaha  dealer repair it if it  does not
function properly.

I g nition circuit cut-off system
This system prevents in-gear engine
starts unless the clutch lever is pulled
and the sidestand is up. Also, it will
stop the running engine should the
sidestand be lowered while the trans-
mission is in gear.
Periodically check the system via the
following procedure.
TIP
 This check is most reliable if per-
formed with a warmed-up engine.
 See pages 3-2 and 3-22 for switch
operation information.

Startin g the eng ine
In order for the ignition circuit cut-off
system (page 3-43) to enable starting,
one of the following conditions must be
met:
 the transmission is in neutral.
 the clutch lever is pulled and the
sidestand up.
To start the engine
1. Turn the main switch to “ON” and set the engine stop switch to “ ”.
2. Confirm the following lights come on for a few seconds, and then go
off. Oil level warning light
 Engine trouble warning light
 TCS indicator light
 Cruise control indicator lights
 Immobilizer system indicator
light
 ABS warning light*
 Neutral indicator light*
TIP
The ABS warning light should go
off when the vehicle reaches a
traveling speed of 10 km/h (6
mi/h).
 The neutral indicator light should
be on when the transmission is in
neutral.

Checkin g the spark plu gs
The spark plugs are important engine
components, which should be
checked periodically, preferably by a
Yamaha dealer. Since heat and depos- its will cause any spark plug to slowly
erode, they should be removed and
checked in accordance with the peri-
odic maintenance and lubrication
chart. In addition, the condition of the
spark plugs can reveal the condition of
the engine.
The porcelain insulator around the
center electrode of each spark plug
should be a medium-to-light tan (the
ideal color when the vehicle is ridden
normally), and all spark plugs installed
in the engine should have the same
color. If any spark plug shows a dis-
tinctly different color, the engine could
be operating improperly. Do not at-
tempt to diagnose such problems
yourself. Instead, have a Yamaha deal-
er check the vehicle.
If a spark plug shows signs of elec-
trode erosion and excessive carbon or
other deposits, it should be replaced.
Before installing a spark plug, the
spark plug gap should be measured
with a wire thickness gauge and, if
necessary, adjusted to specification. Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the spark
plug threads.
TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4–
1/2 turn past finger tight. However, the
spark plug should be tightened to the
specified torque as soon as possible.
NOTICE
ECA10841
Do not use any tools to remove or in-
stall the spark plu
g cap, otherwise
the i gnition coil coupler may  get
