FuelMake sure that there is sufficient fuel
in the tank. Fill the fuel tank to the
bottom of the filler tube as shown.

w8Do not overfill the fuel tank,
otherwise it may overflow
when the fuel warms up and
expands.

cCImmediately wipe off spilled fuel
with a clean, dry, soft cloth, since
fuel may deteriorate painted sur-
faces or plastic parts.

NOTE:
If knocking (or pinging) occurs, use
gasoline of a different brand or with a
higher octane grade.

Fuel cockThis motorcycle is equipped with a
negative pressure fuel cock. The fuel
cock supplies fuel from the tank to
the carburetors while also filtering it.
The fuel cock lever positions are
explained as follows and shown in
the illustrations.
ON
With the fuel cock lever in this posi-
tion, fuel flows to the carburetor when
the engine is running. Turn the fuel
cock lever to this position when start-
ing the engine and riding.1.Arrow mark positioned over ÒONÓ

Tips for reducing fuel
consumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
8Thoroughly warm up the engine.
8Turn the starter (choke) off as
soon as possible.
8Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
8Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the
engine.
8Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cross-
ings).
EAU01128
Engine break-inThere is never a more important peri-
od in the life of your engine than the
period between 0 and 1,600 km. 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 1,600 km. The various parts in
the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheat-
ing must be avoided.
EAU03183
0Ð1,000 km
Avoid prolonged operation above 1/3
throttle.
1,000Ð1,600 km
Avoid prolonged operation above 1/2
throttle.
ECA00058
cCAfter 1,000 km of operation, the
engine oil must be changed and
the oil filter element replaced.1,600 km and beyond
The vehicle can now be operated
normally.
EC000049
cCIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

Periodic maintenance and lubrication chart
NOTE:
8The annual checks must be performed every year, except if a kilometer-based maintenance is performed instead.
8From 30,000 km, repeat the maintenance intervals starting from 6,000 km.

cCBe sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled ÒEnergy
ConservingÓ) contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting in reduced
component life and poor engine performance.
