12 Resetting the traction control sys-
tem
The traction control system will auto-
matically disable when:
the front wheel or rear wheel
comes off the ground while riding.
excessive rear wheel spin is de-
tected while riding.
either wheel is rotated with the key
turned to “ON” (such as when per-
forming maintenance).
If the traction control system is dis-
abled, both the “ ” indicator light and
the “ ” warning light will come on.
Should this occur, try resetting the sys-
tem as follows. 1. Stop the vehicle and turn the key to “OFF”.
2. Wait a few seconds and then turn the key back to “ON”.
3. The “ ” indicator light should turn off and the system be enabled.
TIPIf the “ ” indicator light remains on af-
ter resetting, the vehicle may still be rid-
den; however, have a Yamaha dealercheck the vehicle as soon as possible.
4. Have a Yamaha dealer check the vehicle and turn off the “ ” warn-
ing light.

Quick shift systemThe quick shift system (QS) allows for
full-throttle, clutch lever-less, electroni-
cally-assisted upshifts. When the shift
switch detects motion in the shift pedal
(page 4-14), engine power and drive
torque are momentarily adjusted to al-
low the upshift to occur.TIP
The quick shift system operates
when traveling at least 20 km/h (12
mi/h) with an engine speed of 2300
r/min or higher, and only when ac-
celerating.
It does not operate when the clutchlever is pulled.

Tool kitThe tool kit is in the location shown.
The information included in this manual
and the tools provided in the tool kit are
intended to assist you in the perfor-
mance of preventive maintenance and
minor repairs. However, a torque
wrench and other tools are necessary
to perform certain maintenance work
correctly.TIPIf you do not have the tools or experi-
ence required for a particular job, haveyour Yamaha dealer perform it for you.1. Tool kit

Checking the spark plugsThe spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark plug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter 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 en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
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.

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 speci-
fied torque as soon as possible.NOTICE
ECA10841
Do not use any tools to remove or in-
stall the spark plug cap, otherwise
the ignition coil coupler may get
damaged. The spark plug cap may
be difficult to remove because the
rubber seal on the end of the cap fits
tightly. To remove the spark plug
cap, simply twist it back and forth
while pulling it out; to install it, twistit back and forth while pushing it in.

CanisterThis model is equipped with a canister
to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the fol-
lowing:
Check each hose connection.
Check each hose and canister for
cracks or damage. Replace if dam-
aged.
Make sure that the canister breath-
er is not blocked, and if necessary,
clean it.

Engine oilThe engine oil level should be checked
regularly. In addition, the oil must be
changed and the oil filter cartridge re-
placed at the intervals specified in the
periodic maintenance chart.NOTICE
ECA11621
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a high-
er quality than specified. In
addition, do not use oils labeled
“ENERGY CONSERVING II” or
higher.
Make sure that no foreign mate-rial enters the crankcase.

TIPAn oil filter wrench is available at aYamaha dealer. 5. Apply a thin coat of clean engine oil to the O-ring of the new oil filter
cartridge.
TIPMake sure that the O-ring is properlyseated.
6. Install the new oil filter cartridge, and then tighten to the specified
torque. 7. Install the engine oil drain bolt with
a new gasket, and then tighten the
bolt to the specified torque.
8. Pour the specified amount of the recommended oil into the crank-
case.
TIPUsing a funnel is recommended.
9. After checking the engine oil filler cap O-ring, install the filler cap.TIPWipe off any spilled oil before startingthe engine.
10. Start the engine and let it idle while checking for oil leaks.TIPIf any oil leaks are found which youcannot fix, have the vehicle inspected.

TIPUsing the alignment marks and notch
on each side of the swingarm, make
sure that both drive chain pullers are in
the same position for proper wheelalignment. 3. Tighten the axle nut, then the lock-
nuts to their specified torques.
4. Make sure that the drive chain pull- ers are in the same position, the
drive chain slack is correct, and
the drive chain moves smoothly.

Cleaning and l ubricating the
drive chainThe drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly wear
out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.NOTICE
ECA10584
The drive chain must be lubricated
after washing the motorcycle, ridingin the rain or riding in wet areas.
1. Clean the drive chain with kero- sene and a small soft brush.
NOTICE: To prevent damaging
the O-rings, do not clean the
drive chain with steam cleaners,
high-pressure washers or inap-
propriate solvents.
[ECA11122]
2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive chain with a special O-ring chain
lubricant. NOTICE: Do not use
engine oil or any other lubri-
cants for the drive chain, as they
