NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is
1/4Ð1/2 turn past finger tight.
However, the spark plug should be
tightened to the specified torque as
soon as possible.4.Install the spark plug cap.
5.Install the cowling. Tightening torque:
Spark plug:

must be changed as follows at the
intervals specified in the periodic
maintenance and lubrication chart.
1.Start the engine, warm it up by
riding the scooter for several
minutes, and then stop the
engine.
2.Place the scooter on the center-
stand.NOTE:
Make sure that the scooter is posi-
tioned straight up when checking the
oil level. A slight tilt to the side can
result in a false reading.3.Place an oil pan under the final
gear case to collect the used oil.

CoolantThe coolant reservoir is located
under the battery cover. (See page
6-31 for battery cover removal proce-
dures.)
To check the coolant level
1.Place the scooter on a level sur-
face and hold it in an upright
position.NOTE:
8The coolant level must be
checked on a cold engine since
the level varies with engine tem-
perature.
8Make sure that the scooter is
positioned straight up when
checking the coolant level. A
slight tilt to the side can result in
a false reading.
