7-8 ENGINE LUBRICATION SYSTEM
Engine Oil and Oil Filter
Because of the semi-dry sump lubrication system, the en-
gine oil level indicated on the dipstick will fluctuate depend-
ing on the motorcycle's position and engine speed when the
engine is shut off. To ensure a proper reading of the engine
oil level, follow the Oil Level Inspection procedures closely.
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.
Oil Level Inspection
Situate the motorcycle so that it is vertical.
Remove the oil filler cap/dipstick [A], wipe it dry and thread
in the oil filler cap/dipstick fully clockwise then remove
again to check the oil level.
Check that the engine oil level is between the H (High) [B]
and L (Low) [C] levels on the dip stick.
Situate the motorcycle so that it is perpendicular to the
If the motorcycle has just been used, wait 3 minutes or
more for all the oil to drain down.
If the oil has just been changed or the oil temperature is
low, start the engine and warm it up thoroughly until the
oil temperature in the transmission room goes up about
50°C (122°F). In addition, run the engine at idle speed
for about 30 seconds or more. Do not run the engine
at high engine speed. This fills the oil filter with oil.
Stop the engine, then wait 3 minutes or more until the
Racing the engine before the oil reaches every part
can cause engine seizure.
If the engine oil gets extremely low or if the oil pump
or oil passages clog up or otherwise do not func-
tion properly, the warning indicator light (LED) [A]
and oil pressure warning symbol [B] will light. If
this light stays on when the engine is running above
idle speed, stop the engine immediately and find the
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 off the level in preference
to running the engine with the oil level low. Then at your
earliest convenience, change the oil completely.
