Oil Level Inspection

• Start the engine and run at idle for
approximately five minutes.
• Stop the engine, then wait for at least
three minutes to allow the oil to settle.
• Note the oil level visible in the sight
glass.
• When correct, oil should be visible in
the sight-glass at a point mid-way
between the two horizontal lines
marked on the crankcase.
NOTE
• The actual level is indicated when
the
upright, not on the side stand.
• If it is necessary to top-off the oil level,
remove the filler plug and add oil, a
little at a time, until the level registered
engine or
in the sight glass is correct. On
Scrambler models, a suitable funnel
may be required to add oil to the oil
filler hole.
