7-8 ENGINE LUBRICATION SYSTEM
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.
The engine oil level indicated in the right engine cover
oil level gauge is very sensitive to the motorcycle's posi-
tion and engine rpm at time of shut down. Because of the
semi-dry sump lubrication system with separate oil cham-
bers in the crank room and transmission room, under cer-
tain conditions oil can accumulate in the crank room and
give a false low reading at the oil level gauge, which indi-
cates oil volume in the transmission room.
Engine Oil Level Inspection
Situate the motorcycle so that it is vertical.
Check that the engine oil level is between the upper [A]
and lower levels [B] in the gauge.
Situate the motorcycle so that it is perpendicular to the
If no oil appears in the gauge, tip the motorcycle slightly
to the right until oil is visible then return to an upright po-
sition. If no oil appears even when tipped at an extreme
angle, remove both drain bolts to empty any oil that may
be in the transmission and crankcase, reinstall the drain
bolts and refill with the specified amount of oil.
If the motorcycle has just been used, wait several min-
utes for all the oil to drain down.
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.
Do not run the engine at high engine speed. 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 oil level is too high, remove the excess oil through
the filler opening, using a syringe or some other suitable
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 rather than
running the engine with the oil level low. Then at your
earliest convenience, change the oil completely.
