Tips for reducing fuel
consumption
Your motorcycleÕs fuel consumption
depends to a large extent on your
riding style. The following tips can help
reduce fuel consumption:
lWarm up the engine before riding.
lTurn off the starter (choke) as
soon as possible.
lShift up swiftly and avoid high en-
gine speeds during acceleration.
lDo not double-clutch or rev the en-
gine while shifting down and avoid
high engine speeds with no load
on the engine.
lTurn off the engine instead of let-
ting it idle for an extended length
of time, i.e. in traffic jams, at traffic
lights or railroad crossings.
EAU00436
Engine break-in
There is never a more important period
in the life of your motorcycle than the
period between zero and 1,000 km. For
this reason we ask that you carefully
read the following material. Because
the engine is brand new, you must not
put an excessive load on it for the first
1,000 km. The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full throttle oper-
ation, or any condition which might re-
sult in excessive heating of the engine,
must be avoided.

0 ~ 150 km
Avoid operation above 5,000 r/min.
Stop the engine and let it cool for 5 to
10 minutes after every hour of opera-
tion. Vary the speed of the motorcycle
from time to time. Do not operate it at
one set throttle position.
150 ~ 500 km
Avoid prolonged operation above
6,000 r/min. Rev the motorcycle freely
through the gears, but do not use full
throttle at any time.
500 ~ 1,000 km
Avoid prolonged full throttle operation.
Avoid cruising speeds in excess of
7,000 r/min.
EC000052
CAUTION:
After 1,000 km of operation, be sure
to replace the engine oil and oil fil-
ter.1,000 km and beyond
Full throttle can be used.
EC000053
CAUTION:
lNever let engine speeds enter
the red zone.
lIf any engine trouble should oc-
cur during the break-in period,
consult a Yamaha dealer imme-
diately.

Parking
When parking the motorcycle, stop the
engine and remove the ignition key.
EW000058
The exhaust system is hot. Park the
motorcycle in a place where pedes-
trians or children are not likely to
touch the motorcycle. Do not park
the motorcycle on a slope or soft
ground; the motorcycle may over-
turn.

NOTE:
lThe air filter needs more frequent service if you are riding in unusually wet or dusty areas.

¥ When disassembling the master cylinder or caliper, always replace the brake fluid. Check the brake fluid level regularly
and fill as required.

EAU01880
Spark plug inspection
The spark plug is an important engine
component and should be inspected
periodically, preferably by a Yamaha
dealer. The condition of the spark plug
can indicate the condition of the en-
gine.
Normally, all spark plugs from the
same engine should have the same
color on the white insulator around the
center electrode. The ideal color at this
point is a medium-to-light tan color for a
motorcycle that is being ridden normal-
ly. If one spark plug shows a distinctly
different color, there could be some-
thing wrong with the engine.Do not attempt to diagnose such prob-
lems yourself. Instead, take the motor-
cycle to a Yamaha dealer. The spark
plugs should be periodically removed
and inspected because heat and de-
posits will cause any spark plug to
slowly break down and erode. If elec-
trode erosion becomes excessive, or if
carbon and other deposits are exces-
sive, the spark plug should be replaced
with the specified plug.
Before installing any spark plug, mea-
sure the electrode gap with a wire
thickness gauge and adjust it to speci-
fication.Specified spark plug:
CR8E (NGK) or
U24ESR-N(DENSO)
Spark plug gap:
0.7 ~ 0.8 mm

When installing a spark plug, the gas-
ket surface should always be cleaned
and a new gasket used. Any grime
should be wiped off from the threads
and the spark plug tightened to the
specified torque.
NOTE:
If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4 to 1/2 turn
past finger tight. The spark plug should
be tightened to the specified torque as
soon as possible.Tightening torque:
Spark plug:
12.5 Nm (1.25 mákg)

Engine oil
Oil level inspection
1. Place the motorcycle on the cen-
terstand. Warm up the engine for
several minutes.
NOTE:
Be sure the motorcycle is positioned
straight up when checking the oil level.
A slight tilt toward the side can result in
false readings.
1. Engine oil filler cap
2. With the engine stopped, check
the oil level through the level win-
dow located at the lower part of
the right side crankcase cover.
NOTE:
Wait a few minutes until the oil level
settles before checking.
3. The oil level should be between
the maximum and minimum
marks. If the level is low, fill the en-
gine with sufficient oil to reach the
specified level.

EC000066
CAUTION:
lDo not put in any chemical addi-
tives. Engine oil also lubricates
the clutch and additives could
cause clutch slippage.
lBe sure no foreign material en-
ters the crankcase. Recommended oil:
See page 8-1.
Oil quantity:
Total amount:
3.1 L
Periodic oil change:
2.3 L
With oil filter replacement:
2.6 L
9. Start the engine and warm it up for
several minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.
NOTE:
After the engine is started, the oil level
indicator light should go off if the oil is at
the specified level.
EC000067
CAUTION:
If the indicator light flickers or re-
mains on, immediately stop the en-
gine and consult with a Yamaha
dealer.
