WheelsTo maximize the performance, dura-
bility, and safe operation of your
scooter, note the following points
regarding the specified wheels.
8The wheel rims should be
checked for cracks, bends or
warpage before each ride. If any
damage is found, have a
Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A
deformed or cracked wheel must
be replaced.
8The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced.
An unbalanced wheel can result
in poor performance, adverse
handling characteristics, and a
shortened tire life.
8Ride at moderate speeds after
changing a tire since the tire sur-
face must first be Òbroken inÓ for
it to develop its optimal charac-
teristics.

Engine oil
Type
Recommended engine oil
classificationAPI Service SE, SF, SG type
or highercCBe sure to use motor oils that do not contain anti-friction
modifiers. Passenger car motor oils (often labeled ÒEnergy
ConservingÓ) contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting in reduced
component life and poor engine performance.
