EAU15950
WARNING

EWA10270

Become thoroughly familiar
with all operating controls and
their functions before riding.
Consult a Yamaha dealer re-
garding any control or function
that you do not thoroughly un-
derstand.

Never start the engine or oper-
ate it in a closed area for any
length of time. Exhaust fumes
are poisonous, and inhaling
them can cause loss of con-
sciousness and death within a
short time. Always make sure
that there is adequate ventila-
tion.

Before starting out, make sure
that the sidestand is up. If the
sidestand is not raised com-
pletely, it could contact the
ground and distract the opera-
tor, resulting in a possible loss
of control.

Engine break-in
There 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 follow-
ing 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.
EAU16990
0–500 km (0–300 mi)
Avoid prolonged operation above 1/3
throttle.
500–1000 km (300–600 mi)
Avoid prolonged operation above 1/2
throttle.
CAUTION:

ECA11500
After 1000 km (600 mi) of operation,the engine oil must be changed, and
the oil filter element and the oil
strainer cleaned.
1000 km (600 mi) and beyond
The vehicle can now be operated nor-
mally.
CAUTION:

ECA10270
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
EAU17170
Parking
When parking, stop the engine, remove
the key from the main switch, and then
turn the fuel cock lever to “OFF”.

9 To charge the battery
Have a Yamaha dealer charge the bat-
tery as soon as possible if it seems to

1. If the vehicle will not be used for
more than one month, remove the
battery, fully charge it, and then
place it in a cool, dry place.
2. If the battery will be stored for more
than two months, check it at least
once a month and fully charge it if
necessary.
3. Fully charge the battery before in-
stallation.
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals.
CAUTION:

ECA10630

Always keep the battery
charged. Storing a discharged
battery can cause permanentbattery damage.

battery, a special (constant-volt-
age) battery charger is required.

If you do not have access to a
sealed-type (MF) battery charg-
er, have a Yamaha dealer
charge your battery.
