TIPThe spring preload setting is determined by
measuring distance A, shown in the illustration.
 The shorter distance A is, the greater the spring
preload. The longer distance A is, the lesser the
spring preload.
 Each complete turn of the adjusting nut chang-
es distance A by 1.5 mm (0.06 in).
3. Tighten the locknut to the specified torque.
NOTICE: Always tighten the locknut
against the adjusting nut, and then tighten
it to the specified torque.

Turn the rebound damping force adjusting screw
in direction (a) to increase the rebound damping
force. Turn in direction (b) to decrease the re-
bound damping force.
Spring preload setting:
Minimum (soft):Distance A = 268.0 mm (10.55 in)
Standard: Distance A = 262.0 mm (10.31 in)

The spring preload setting is determined by
measuring distance A, shown in the illustration.
The shorter distance A is, the higher the spring
preload; the longer distance A is, the lower the
spring preload. With each complete turn of the
adjusting nut, distance A is changed by 1.5 mm
(0.06 in).

3. Tighten the locknut to the specified torque.
NOTICE: Always tighten the locknut
against the adjusting nut, and then tighten
it to the specified torque.

EBU27113Owner’s Manual and tool kitBe sure to put the Owner’s Manual in the plastic
bag and to always carry it as well as the tool kit
and the low-pressure tire gauge in their respective
compartments under the seat.
The information included in this manual and the
tools provided in the tool kit are intended to assist
you in the performance of preventive maintenance
and minor repairs. However, additional tools such
as a torque wrench are necessary to perform cer-
tain maintenance work correctly.
TIPIf you do not have the tools or experience required
for a particular job, have a Yamaha dealer perform
it for you.

2. Check the spark plug for electrode erosion
and excessive carbon or other deposits, and
replace it if necessary.
3. Measure the spark plug gap with a wire thick- ness gauge and, if necessary, adjust the gap
to specification. To install the spark plug
1. Clean the surface of the spark plug gasket and its mating surface, and then wipe off any
grime from the spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tighten it to the specified
torque.
TIPIf a torque wrench is not available when installing
the 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. 3. Install the spark plug cap.
Specified spark plug:

7. Remove the oil filter element and the O-rings. 8. Install a new oil filter element and new O-
rings.
TIPMake sure that the O-rings are properly seated. 9. Install the oil filter element cover by installingthe bolts, and then tighten them to the speci-
fied torque.

engine oil tank drain bolt and their new gas-
ket, and then tighten the bolts to the specified
torques.
11. Install the crankcase engine oil filler bolt and its new O-ring, and then tighten the oil filler
bolt to the specified torque.
12. Pour only 1.3 L (1.37 US qt, 1.14 Imp.qt) of the specified amount of the recommended
engine oil through the engine oil tank filler
hole, and then install and tighten the oil tank
filler cap.
13. Start the engine, rev it several times, and then turn it off. 14. Remove the engine oil tank filler cap, and
then gradually fill the oil tank with the remain-
ing oil quantity while regularly checking the oil
level on the dipstick.
15. Check the O-ring for damage, and replace it if necessary.
16. Install and tighten the engine oil tank filler cap.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down. NOTICEECB00301In order to prevent clutch slippage (since the
engine oil also lubricates the clutch), do not
mix any chemical additives. Do not use oils
Tightening torques:
Crankcase engine oil drain bolt:23 N·m (2.3 kgf·m, 17 lb·ft)
Engine oil tank drain bolt: 19 N·m (1.9 kgf·m, 14 lb·ft)
Tightening torque: Crankcase engine oil filler bolt:12 N·m (1.2 kgf·m, 8.9 lb·ft)Recommended oil:See page 11-1.
Oil quantity: Without oil filter element replacement:1.75 L (1.85 US qt, 1.54 Imp.qt)
With oil filter element replacement: 1.85 L (1.96 US qt, 1.63 Imp.qt)

6. Disconnect the coolant reservoir hose on the
coolant reservoir side, and then drain the
coolant from the coolant reservoir.
7. After draining the coolant, thoroughly flush the cooling system with clean tap water.
8. Install the coolant drain bolt and its new gas- ket, and then tighten the bolt to the specified
torque.

brush to remove any carbon deposits from
the spark arrester portion of the tailpipe and
inside of the tailpipe housing. 4. Install the gasket, tailpipe, and retainer and
align the bolt holes.
5. Install the bolts and tighten them to the spec- ified torque.

WARNING
EWB02342Always let the exhaust system cool prior to
touching exhaust components.
Do not start the engine with the spark arrester
removed. Sparks or exhaust particulate can
cause eye injury, burns, or start a fire. EBU26812Adjusting the engine idling speedThe engine idling speed must be checked and, if
necessary, adjusted as follows at the intervals
specified in the periodic maintenance and lubrica-
tion chart.TIPA diagnostic tachometer is needed to make this
adjustment. 1. Start the engine and warm it up.
2. Attach the tachometer to the spark plug lead.3. Check the engine idling speed and, if neces-
sary, adjust it to specification by turning the
idle adjusting screw. To increase the engine
idling speed, turn the idle adjusting screw in
direction (a), and to decrease it, turn the
screw in direction (b).
