Quick shift system
The 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.
TIP
The 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 spee d, when
d ownshiftin g, or if the quick shift
system is off.

This model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, fast compres-
sion damping force, and slow
compression damping force can be
adjusted.
NOTICE
ECA10102
To avoi d d amag ing the mechanism,
d o not attempt to turn beyon d the
maximum or minimum settin gs.
Sprin g preloa d
1. Loosen the locknut.
2. To increase the spring preload and thereby harden the suspen-
sion, turn the adjusting nut in di-
rection (a). To decrease the spring
preload and thereby soften the
suspension, turn the adjusting nut
in direction (b).
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 owner’s tool kit to make
the adjustment. 3. Tighten the locknut to the speci-
fied torque. NOTICE: Always
ti ghten the locknut ag ainst the
a d justin g nut, and then tighten
the locknut to the specifie d
torque.

Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replace-
ment, or repair of the emission control
devices and systems may be per-
formed by any repair establishment or
individual that is certified (if applicable).
Yamaha dealers are trained and equipped to perform these particular
services.
EAU67090
Owner’s tool kit
The owner’s tool kit should be stored
separately from the vehicle. However,
there are two hexagon wrenches
stored under the passenger seat. (See
page 4-23.)
The service information included in this
manual and the tools provided are in-
tended to assist you in the perfor-
mance of preventive maintenance and
minor repairs. However, additional
tools, such as a torque wrench, are
necessary to perform certain mainte-
nance work correctly.
TIP
If you do not have the tools or experi-
ence required for a particular job, have
a Yamaha dealer perform it for you.

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
d ama ged . The spark plu g cap may
b e difficult to remove b ecause 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 b ack and forth
while pullin g it out; to install it, twist
it back an d forth while pushin g it in.

Canister
This 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.

Make 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 be ab le
to shift up or down.

Using 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.

Cleanin g an d lu bricatin g the
d rive chain
The 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 lu bricate 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.
[ECA11122]
2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive chain with a special O-ring chain
lubricant. NOTICE: Do not use
en gine oil or any other lu bri-
cants for the drive chain, as they
may contain su bstances that
coul d damag e the O-rin gs.
