Engine Oil - Yamaha Xmax 250 Owner's Manual

1. Measure the spark plug gap with
a wire thickness gauge and, if
necessary, adjust the gap to spe-
cification.
Spark plug gap:
0.6 ~ 0.7 mm (0.023 ~ 0.027 in)
2. Clean the surface of the spark
plug gasket and its mating surfa-
ce, and then wipe off any grime
from the spark plug threads.
3. Install the spark plug with the
spark plug wrench, and then
tighten it to the specified torque.
Tightening torque:
Spark plug:
18 Nm (1.8 m•kgf, 13.0 ft•lbf)
NOTE:
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4 ~
1/2 turn past finger tight. However,
the spark plug should be tightened to
the specified torque as soon as pos-
sible.
4. Install the spark plug cap.

Engine oil

The engine oil level should be chec-
ked before each ride. In addition, the
oil must be changed at the intervals
specified in the periodic maintenance
and lubrication chart and when the
service indicator light comes on.
To check the engine oil level
1. Place the scooter on the centers-
tand.
NOTE:
Make sure that the scooter is positio-
ned straight up when checking the oil
level. A slight tilt to the side can result
in a false reading.
2. Start the engine, warm it up for
several minutes, and then turn it
off.
