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 following 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 themsel-
ves to the correct operating clearan-
ces. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAU16860
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.
500~1000 km (300~600 mi)
Avoid prolonged operation above 3/4
throttle.
ECA10280
CAUTION
After 1000 km (600 mi) of operation,
the engine oil must be changed.
1000 km (600 mi) and beyond
Avoid prolonged full-throttle opera-
tion. Vary the speed occasionally.
ECA10270
CAUTION
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, remo-
ve the key from the main switch, and
then turn the fuel cock lever to “OFF”.
EWA10310

to touch them.
Do not park on a slope or on
soft ground, otherwise the
vehicle may overturn.

WARNING
Electrolyte is poisonous and
dangerous since it contains
sulfuric acid, which causes
severe burns. Avoid any con-
tact with skin, eyes or clothing
and always shield your eyes
when working near batteries.
In case of contact, administer
the following FIRST AID.
• EXTERNAL: Flush with plenty
of water.
• INTERNAL: Drink large quan-
tities of water or milk and
immediately call a physician.
• EYES: Flush with water for 15
minutes and seek prompt
medical attention.
Batteries produce explosive
hydrogen gas. Therefore,
keep sparks, flames, cigaret-
tes, etc., away from the bat-
tery and provide sufficient
ventilation when charging it in
an enclosed space.
KEEP THIS AND ALL BATTE-
RIES OUT OF THE REACH OF
CHILDREN.
To store the battery
1. If the motorcycle 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
installation.
4. After installation, make sure that
the battery leads are properly
connected to the battery termi-
nals.
ECA10630
CAUTION
Always keep the battery char-
ged. Storing a discharged bat-
tery can cause permanent bat-
tery damage.
To charge a sealed-type (MF)
battery, a special (constant-
voltage) battery charger is
required. Using a conventional
battery charger will damage
the battery. If you do not have
access to a sealed-type (MF)
battery charger, have a Yamaha
dealer charge your battery.

2. Remove the blown fuse, and then
install a new fuse of the specified
amperage.
ECA10640
CAUTION
Do not use a fuse of a higher ampe-
rage rating than recommended to
avoid causing extensive damage to
the electrical system and possibly a
fire.
3. Turn the key to “ON” and turn on
the electrical circuits to check if the
devices operate.
4. If the fuse immediately blows
again, have a Yamaha dealer check
the electrical system.

WARNING
Headlight bulbs get very hot. The-
refore, keep flammable products
away from a lit headlight bulb, and
do not touch the bulb until it has
cooled down.
3. Place a new headlight bulb into
position, and then secure it with
the bulb holder.
ECA10660
CAUTION
Do not touch the glass part of the
headlight bulb to keep it free from
oil, otherwise the transparency of
the glass, the luminosity of the
bulb, and the bulb life will be adver-
sely affected. Thoroughly clean off
any dirt and fingerprints on the
headlight bulb using a cloth mois-
tened with alcohol or thinner.
4. Connect the headlight lead con-
nectors, and then install the bulb
cover.
