Quick shift systemThe quick shift system allows for full-
throttle, clutch lever-less upshifts.
When the shift switch detects motion
in the shift pedal, engine power and
drive torque are momentarily adjusted
to allow the upshift to occur.TIPThe quick shift system operates when
traveling at least 20 km/h (12 mi/h) with
an engine speed of 2000 r/min or high-
er, and only when accelerating. It does
not operate when the clutch lever is
pulled.NOTICE
ECA26260
To prevent drivetrain damag e, al-
ways use the clutch lever to shift
when ri din g at slow speed , when
d ownshiftin g, or if the quick shift
system is off.

1. Loosen the locknut.
2. Turn the adjusting nut in direction (a) to increase the spring preload.
Turn the adjusting nut in direction
(b) to decrease the spring preload.
The spring preload setting is de-
termined by measuring distance
A. The longer distance A is, the
higher the spring preload; the
shorter distance A is, the lower the
spring preload. 
Use the special wrench and
the extension bar included in
the tool kit to make the ad-
justment.
3. Tighten the locknut to the speci-fied torque. NOTICE: Always

Turn the adjusting bolt in direction (a)
to increase the rebound damping
force.
Turn the adjusting bolt in direction (b)
to decrease the rebound damping
force.
To set the rebound damping force, turn
the adjuster in direction (a) until it
stops, and then count the clicks in di-
rection (b).

Tool kitThe tool kit should be stored separate-
ly from the vehicle. However, there are
some tools located under the seat.
(See page 4-22.)
The information included in this manual
and the tools provided are intended to
assist you in the performance of pre-
ventive maintenance and minor re-
pairs. 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, have
your Yamaha dealer perform it for you.1. Hexagon wrench

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.
TIPIf 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
d amag ed . The spark plu g cap may
b e difficult to remove because the
ru bber seal on the en d of the cap fits
ti g htly. To remove the spark plu g
cap, simply twist it back an d forth
while pullin g it out; to install it, twist
it back an d forth while pushin g 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
following:
 Check each hose connection.
 Check each hose and canister for
cracks or damage. Replace if
damaged.
 Make sure that the canister
breather is not blocked, and if
necessary, clean it.

TIPAn oil filter wrench is available at a
Yamaha dealer.9. 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 properly
seated.10. Install the new oil filter cartridge with an oil filter wrench, and then
tighten it to the specified torque
with a torque wrench. 11. Install the fuel tank overflow hose
into the guides, then place them in
their original position.
12. Install the shift arm by aligning the slot in the shift arm with the mark
on the shift shaft and installing the
shift arm bolt, then tightening it to
the specified torque. NOTICE: Be
sure to ali gn the slot an d mark
to ensure proper shiftin g. If the
slot an d mark are not ali gne d,
the shift arm will not move cor-
rectly an d you may not b e able
to shift up or down.

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

Cleanin g an d lu bricatin g the
d rive 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

The drive chain must b e lubricate d
after washin g the motorcycle, ri din g
in the rain or ri din g in wet areas.1. Clean the drive chain with kero-
sene and a small soft brush.
NOTICE: To prevent d amaging
the O-rin gs, do not clean the
d rive chain with steam cleaners,
hi gh-pressure washers or inap-
propriate solvents.
