1-OPERATION
Read the Owner’s Manual carefully to be-
come familiar with all controls. If there is a
control or function you do not understand, ask
your Yamaha dealer.
WARNING
Failure to familiarize yourself with the con-
trols can lead to loss of control, which
could cause an accident or injury.
Engine break-in
There is never a more important period in the
life of your vehicle than the period between 0
and 20 hours.
For this reason, we ask that you read the fol-
lowing material carefully. Because the engine
is brand new, you must not put an excessive
load on it for the first several hours of opera-
tion. During the first 20 hours, the various
parts in the engine wear and polish them-
selves to achieve the correct operating clear-
ances.
During this period, prolonged full-throttle oper-
ation or any condition that might result in ex-
cessive engine heating must be avoided.
However, momentary (2–3 seconds maxi-
mum) full-throttle operation under load does
not harm the engine.

14. Insert the projections on the air filter casecover into the holders on the air filter
case, and then install the air filter case
cover by hooking the holders onto the
cover.1. Projection ( × 2) 2. Holder ( × 2)15. Install the air intake duct shroud by in-
stalling the quick fastener screws.
16. Close the hood. The air filter element should be cleaned every
20–40 hours. It should be cleaned and lubri-
cated more often if the vehicle is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions.
Check the air filter element rubber joint to the
throttle body and manifold fittings for an air-
tight seal. Tighten all fittings securely to avoid
the possibility of unfiltered air entering the en-
gine.
NOTICENever operate the engine with the air filter
element removed. This will allow unfiltered
air to enter, causing rapid engine wear and
possible engine damage. Additionally, op-
eration without the air filter element will af-
fect the fuel injection system with
subsequent poor performance and possi-
ble engine overheating.

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you. Place a thick rag over the cap and remove the cap slowly to allow any remaining
pressure to escape.
If it is difficult to get the recommended coolant , tap water can be used temporarily, provided that
it is changed to the recommended coolant as soon as possible.Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See the text below.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.
