plug wrench, and then tighten it to
the specified torque.
Tightening torque:
Spark plug:
25 Nm (2.5 m·kgf, 18 ft·lbf)
TIP
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 speci-
fied torque as soon as possible.
3. Install the spark plug cap.
Engine oil and oil filter
element
The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter ele-
ment replaced at the intervals specified
in the periodic maintenance and lubri-
cation chart.
To check the engine oil level
1. Start the engine, warm it up for
several minutes, and then turn it
off.
2. On a level surface, place the vehi-
cle on the centerstand.
3. Wait a few minutes until the oil set-
tles. Remove the engine oil filler
cap, wipe the dipstick clean, insert
it back into the oil filler hole (with-
out screwing it in), and then re-
move it again to check the oil level.
WARNING! Never remove the
engine oil filler cap after high-
speed operation, otherwise hot
engine oil could spout out and
cause damage or injury. Always
let the engine oil cool down suf-
ficiently before removing the oil
filler cap.
