a confined area. Exhaust fumes are
poisonous and can cause
consciousness and death within a short
period of time. Always operate your
motorcycle in the open-air or in an area
with adequate ventilation.
Caution
Running the engine with insufficient oil will
cause engine damage. If the low oil
pressure indicator remains on, stop the
engine immediately and investigate the
cause.

Start the engine and run at idle for
approximately five minutes.
Stop the engine and wait for three minutes to
allow the oil to settle.
With the motorcycle upright, remove the filler
loss of
plug/dipstick, wipe the blade clean and screw
it fully home.
Remove the filler plug/dipstick.
The oil level is indicated by lines on the filler
plug/dipstick. When full, the indicated oil
level must be level with the upper marking
on the dipstick.
If the oil level is below the lower marking,
add oil a little at a time until the correct level
is reached. Once the correct level is reached,
re-install the filler plug/dipstick.
