4. Always inspect the aluminum wheels
before a ride. Place the motorcycle on
the center stand and check for cracks,
bends or warpage of the wheels. If any
abnormal condition exists in a wheel,
consult your Yamaha dealer or other
qualified mechanic. Do not attempt
even small repairs to the wheel. If a
wheel is deformed or cracked, it must
be replaced.
5. Tires and wheels should be balanced
whenever either one is changed or re-
placed. Failure to have a wheel assem-
bly balanced can result in poor perform-
ance, adverse handling characteristics,
and shortened tire life.
6. After installing a tire, ride conservatively
to allow the tire to seat itself on the rim
properly. Failure to allow proper seating
may cause tire failure resulting in
damage to the motorcycle and injury to
the rider.
7. After repairing or replacing a tire, check
to be sure the valve stem lock nut is
securely fastened. If not, torque it as
specified.
Tightening torque: 0.15 m-kg (1.1 ft-lb)
The standard equipment tires originally fitted
to the XS850G are suited to normal riding
and touring. They are not suited for sustained
high speed running or racing and must not be
used for such purposes. Consider your riding
skill, road and weather conditions, and cor-
rect weight distribution when loading your
motorcycle. Securely pack your heaviest
items close to the center of the motorcycle.
