Checking oil level
Check the oil level at regular
intervals.
Always check the oil level when
the engine is at operating tem-
perature, because the differ-
ence between the oil level
indicated when the engine is at
operating temperature and the
oil level indicated when the
engine is very cold due to
extremely low outdoor
temperatures (14 °F/-10 °C)
can be as much as 0.3937 in
(10 mm).
After switching off the engine,
wait at least 5 minutes for the oil
to drain back into the sump.
Checking the oil level after the
engine has been run only briefly
or when it is not properly warm
will falsify the reading and could
lead to the engine being oper-
ated with the wrong quantity of
oil, because cold oil is viscous
and takes longer to drain back
into the sump. At extremely low
outdoor temperatures
(14 °F/-10 °C), this can take as
long as 12 hours.
To avoid damage to the engine:
– Never exceed the maximum
oil level.
– Always keep the oil level
above the minimum mark.
Always check the oil level with
the motorcycle upright.
• Check the oil level with the
engine at its regular operating
temperature
• Check the oil level after the
engine has been stopped for
at least 5 minutes
• Make sure that the motorcy-
cle is upright
– Make sure the ground is
level and firm
