3 Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
EAU13434
Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire hazar
d or
b urns:
Do not park the vehicle near
possi ble fire hazard s such as
g rass or other materials that
easily burn.
Park the vehicle in a place
where ped estrians or chil dren
are not likely to touch the hot
exhaust system.
Make sure that the exhaust sys-
tem has coole d down before
d oin g any maintenance work.
Do not allow the en gine to id le
more than a few minutes. Lon g
i d lin g can cause a b uild-up of
heat.
NOTICE
ECA10702
Use only unlea ded g asoline. The use
of lead ed g asoline will cause unre-
pairab le damag e to the catalytic
converter.

Tips for re ducin g fuel con-
sumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
Avoid high engine speeds during
acceleration.
Avoid high engine speeds with no
load on the engine.
Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at traf-
fic lights or at railroad crossings).

EAU16831
En gine break-inThere is never a more important period
in the life of your engine than the period
between 0 and 1000 km (600 mi). For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1000 km (600 mi). The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
EAU61040
0–150 km (0–90 mi)
Avoid prolonged operation above 1/3
throttle.
After every hour of operation, stop the
engine, and then let it cool for five to
ten minutes.
Vary the engine speed from time to
time. Do not operate the engine at one
set throttle position. 150–500 km (90–300 mi)
Avoid prolonged operation above 1/2
throttle.
Rev the engine freely through the
gears, but do not use full throttle at any
time.
500–1000 km (300–600 mi)
Avoid prolonged operation above 3/4
throttle.
1000 km (600 mi) an
d b eyon d
Avoid prolonged full-throttle operation.
Vary the engine speed occasionally.
NOTICE: After 1000 km (600 mi) of
operation, be sure to chan ge the en-
g ine oil an d final transmission oil,
an d to clean the oil strainer.

Parkin gWhen parking, stop the engine, and
then remove the key from the main
switch.

Since the en gine an d exhaust
system can become very hot,
park in a place where pe destri-
ans or chil dren are not likely to
touch them an d b e burne d.
Do not park on a slope or on soft

may overturn, increasin g the
risk of a fuel leak an d fire.
Do not park near grass or other

TIP The annual checks must be performed every year, except if a kilometer- based maintenance, or for the UK, a
milea ge- base d maintenance, is performe d instea d.
From 20000 km (12000 mi), repeat the maintenance intervals starting from 4000 km (2400 mi).
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and tech-
nical skills.

Trou bleshootin gAlthough Yamaha vehicles receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems,
for example, can cause poor starting
and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your vehicle re-
quire any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the vehicle prop-
erly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
WARNING
EWA15142
When checkin g the fuel system, d o
not smoke, an d make sure there are
no open flames or sparks in the ar-
ea, inclu din g pilot li ghts from water heaters or furnaces. Gasoline or
g
asoline vapors can i gnite or ex-
plo de, causin g severe injury or prop-
erty damag e.
