Engine Oil and Oil Filter
Motorcycle operation with insufficient, deteri-
orated, or contaminated engine oil will cause
accelerated wear and may result in engine or trans-
mission seizure, accident, and injury.
Engine Oil Level Inspection
If the oil has just been changed, start the engine and run
it for several minutes at idle speed. This fills the oil filter
with oil. Stop the engine, then wait several minutes until
the oil settles.
Racing the engine before the oil reaches every part
can cause engine seizure.
If the motorcycle has just been used, wait several minutes
for all the oil to drain down.
Situate the motorcycle so that it is perpendicular to the
ground, and check the engine oil level through the oil level
The oil level should come up between the upper [A] and
lower [B] level lines.
If the oil level is too high, remove the excess oil, using a
syringe or some other suitable device.
If the oil level is too low, add the correct amount of oil
through the oil filler opening. Use the same type and
make of oil that is already in the engine.
If the engine oil type and make are unknown, use any
brand of the specified oil to top up the level in preference
to running the engine with the oil level low. Then at your
earliest convenience, change the oil completely.
If the engine oil gets extremely low or if the oil pump
or oil passages clog up or otherwise do not function
properly, the oil pressure warning light will light. If
this light stays on when the engine is running above
idle speed, stop the engine immediately and find the
