Engine Oil
Engine oil quality is the chief factor affecting engine
service life. Change the engine oil as specified in the
maintenance schedule (page 40).
When running in very dusty conditions, oil changes
should be performed more frequently than specified
in the maintenance schedule.
Please dispose of used engine oil in a manner that
is compatible with the environment. We suggest you
take it in a sealed container to your local recycling
center or service station for reclamation. Do not throw
it in the trash or pour it on the ground or down a drain.
Used engine oil may cause skin cancer if repeatedly
left in contact with the skin for prolonged periods.
Although this is unlikely unless you handle used oil
on a daily basis, it is still advisable to thoroughly wash
your hands with soap and water as soon as possible
after handling used oil.
Changing the oil requires a torque wrench. If you do
not have it and the necessary skill, we recommend
that you have your Honda dealer perform this service.
If a torque wrench is not used for this installation,
see your Honda dealer as soon as possible to verify
proper assembly.
Change the engine oil with the engine at normal
operating temperature and the motorcycle on its side
stand to assure complete and rapid draining.
1. Remove the oil fill cap/dipstick from the right
crankcase cover.
2. Place a drain pan under the crankcase.
3. Remove the oil drain plug (1), O-ring (2), spring
(3) and oil strainer screen (4).
4. Clean the oil strainer screen.
5. Check that the oil strainer screen and sealing
rubber are in good condition.
6. Replace the O-ring and apply a thin coat of
engine oil to the new O-ring before installing it.
7. Install the O-ring to the oil drain plug.
8. Install the oil strainer screen, spring and drain
plug.
Oil drain plug torque:
15 N.m (1.5 kgf.m, 11 lbf.ft)
9. Fill the crankcase with the recommended grade
oil; approximately:
1.0 liter (1.1 US qt, 0.9 Imp qt)
