Ig 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 4-2 and 4-4 for switch
operation information.

Startin g the en gine
In order for the ignition circuit cut-off
system (page 4-31) to enable starting,
one of the following conditions must be
met:
 The transmission is in the neutral
position.
 The transmission is in gear with
the clutch lever pulled and the
sidestand up.
To start the engine
1. Turn the key to “ON” and make sure that the engine stop switch is
set to “ ”.
2. Confirm that the following lights perform a circuit check (come on
for a few seconds and then go off). Engine trouble warning light
 ABS warning light*
 Oil level warning light
 Fuel level warning light*
 Coolant temperature warning
light
 Traction control system indi-
cator light
 Shift timing indicator light
 Immobilizer system indicator
light
TIP
 The ABS warning light should
come on and stay on until the ve-
hicle reaches a traveling speed of
10 km/h (6 mi/h).
 The fuel level warning light will
stay on if you are low on fuel.
NOTICE
ECA24110
If a warnin g or in dicator li ght does
not work as descri bed a bove, have a
Yamaha dealer check the vehicle.
3. Shift the transmission into the
neutral position (or hold the clutch
lever pulled with the sidestand up).
4. Push the start switch “ ” to crank the engine with the starter.
Release the start switch when the
engine starts, or after 5 seconds.
Wait 10 seconds before pressing

Tips for re ducin g fuel con-
sumption
Fuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
 Shift up swiftly, and avoid high en-
gine speeds during acceleration.
 Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the en-
gine.
 Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).
EAU16842
Engine break-in
There is never a more important period
in the life of your engine than the period
between 0 and 1600 km (1000 mi). For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAU17085
0–1000 km (0–600 mi)
Avoid prolonged operation above 8300
r/min. NOTICE: After 1000 km (600
mi) of operation, the en gine oil must

tri dge or element replace d.
[ECA10303]

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.
