OIL FILTER
Change
1. Drain the engine oil, and retighten the drain bolt securely.
2. Remove the oil filter, and drain the oil into a suitable container.
Dispose the used oil and filter in a manner compatible with the
environment.
Use an oil filter socket, rather than a strap wrench, to avoid
striking and damaging the oil pressure switch.
SEAL
FILTER MOUNTING BASE
3. Clean the filter mounting base, and coat the seal of the new oil
filter with clean engine oil.
Use only a Honda Genuine oil filter or a filter of equivalent
quality specified for your model. Using the wrong filter, or a
non-Honda filter which is not of equivalent quality, may cause
engine damage.
4. Screw on the new oil filter by hand until the seal contacts the
filter mounting base, and then use an oil filter socket tool to
tighten the filter an additional 3/4 turn.
Oil filter tightening torque: 12 N·m (1.2 kgf·m, 9 lbf·ft)
5. Refill the crankcase with the specified amount of the
recommended oil (see page 8). Reinstall the oil filler cap and oil
level dipstick.
6. Start the engine, and check for leaks.
7. Stop the engine, and check the oil level as described on page 8.
If necessary, add oil to bring the oil level to the upper limit mark
on the oil level dipstick.

AIR CLEANER
A dirty air cleaner will restrict air flow to the carburetor, reducing
engine performance. If you operate the engine in very dusty areas,
clean the air filter more often than specified in the MAINTENANCE
SCHEDULE (see page 7).
Operating the engine without an air filter, or with a damaged air
filter, will allow dirt to enter the engine, causing rapid engine wear.
This type of damage is not covered by the Distributor's Limited
Warranty.
Inspection
Remove the air cleaner cover and inspect the filter elements.
Clean or replace dirty filter elements. Always replace damaged filter
elements.
Cleaning
1. Pull the air cleaner cover latch to the unlocked position, and
remove the cover.
2. Remove the wing nut from the paper filter element.
3. Remove the paper filter element and foam filter element from
the air cleaner case.
4. Remove the foam filter element from the paper filter element.
