WARNING
EAS00162
CHECKING THE TIRES
The following procedure applies to both of the
tires.
1. Check:
tire pressure
Out of specification Regulate.
The tire pressure should only be checked
and regulated when the tire temperature
equals the ambient air temperature.
The tire pressure and the suspension must
be adjusted according to the total weight
(including cargo, rider, passenger and ac-
cessories) and the anticipated riding
speed.
Operation of an overloaded motorcycle
could cause tire damage, an accident or an
injury.
NEVER OVERLOAD THE MOTORCYCLE.

Do not use a tubeless tire on a wheel de-
signed only for tube tires to avoid tire fail-
ure and personal injury from sudden defla-
tion.
When using a tube tire, be sure to install the
correct tube.
Always replace a new tube tire and a new
tube as a set.
To avoid pinching the tube, make sure the
wheel rim band and tube are centered in the
wheel groove.
Patching a punctured tube is not recom-
mended. If it is absolutely necessary to do
so, use great care and replace the tube as
soon as possible with a good quality re-
placement.

After extensive tests, the tires listed below
have been approved by Yamaha Motor Co.,
Ltd. for this model. The front and rear tires
should always be by the same manufacturer
and of the same design. No guarantee con-
cerning handling characteristics can be giv-
en if a tire combination other than one ap-
proved by Yamaha is used on this
motorcycle.

New tires have a relatively low grip on the
road surface until they have been slightly
worn. Therefore, approximately 100 km
should be traveled at normal speed before
any high-speed riding is done.
For tires with a direction of rotation mark
1:
Install the tire with the mark pointing in the
direction of wheel rotation.
Align the mark
2 with the valve installation
point.

CHECKING AND CHARGING THE BATTERY
CHK
ADJ
WARNING
CAUTION:
EAS00178
ELECTRICAL SYSTEM
CHECKING AND CHARGING THE BATTERY
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of poi-
sonous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:
Wear protective eye gear when handling or
working near batteries.
Charge batteries in a well-ventilated area.
Keep batteries away from fire, sparks or
open flames (e.g., welding equipment,
lighted cigarettes).
DO NOT SMOKE when charging or han-
dling batteries.
KEEP BATTERIES AND ELECTROLYTE
OUT OF REACH OF CHILDREN.
Avoid bodily contact with electrolyte as it
can cause severe burns or permanent eye
injury.
FIRST AID IN CASE OF BODILY CONTACT:
EXTERNAL
Skin – Wash with water.
Eyes – Flush with water for 15 minutes and
get immediate medical attention.
INTERNAL
Drink large quantities of water or milk fol-
lowed with milk of magnesia, beaten egg or
vegetable oil. Get immediate medical atten-
tion.
This is a sealed battery. Never remove the
sealing caps because the balance between
cells will not be maintained and battery per-
formance will deteriorate.
Charging time, charging amperage and
charging voltage for an MF battery are dif-
ferent from those of conventional batter-
ies. The MF battery should be charged as
explained in the charging method illustra-
tions. If the battery is overcharged, the
electrolyte level will drop considerably.
Therefore, take special care when charging
the battery.

CHECKING AND CHARGING THE BATTERY
CHK
ADJ
WARNING
CAUTION:
5. Charge:
battery
(refer to the appropriate charging method il-
lustration)
Do not quick charge a battery.
Never remove the MF battery sealing caps.
Do not use a high-rate battery charger
since it forces a high-amperage current
into the battery quickly and can cause bat-
tery overheating and battery plate damage.
If it is impossible to regulate the charging
current on the battery charger, be careful
not to overcharge the battery.
When charging a battery, be sure to remove
it from the motorcycle. (If charging has to
be done with the battery mounted on the
motorcycle, disconnect the negative bat-
tery lead from the battery terminal.)
To reduce the chance of sparks, do not
plug in the battery charger until the battery
charger leads are connected to the battery.
Before removing the battery charger lead
clips from the battery terminals, be sure to
turn off the battery charger.
Make sure the battery charger lead clips
are in full contact with the battery terminal
and that they are not shorted. A corroded
battery charger lead clip may generate heat
in the contact area and a weak clip spring
may cause sparks.
If the battery becomes hot to the touch at
any time during the charging process, dis-
connect the battery charger and let the bat-
tery cool before reconnecting it. Hot batter-
ies can explode!
As shown in the following illustration, the
open-circuit voltage of an MF battery stabi-
lizes about 30 minutes after charging has
been completed. Therefore, wait 30 min-
utes after charging is completed before
measuring the open-circuit voltage.
