Oil Filter Change (if equipped)
1. Drain the engine oil (see page 5).
2. Remove the oil filter with an oil filter wrench and let the remaining
oil drain out. Discard the oil filter.
NOTICE
Use a socket-type wrench to remove and install the oil filter. If other
types of oil filter wrenches must be used, be careful to avoid hitting
and damaging the fuel line or fuel tank connection.
3. Clean the filter base.
4. Coat the gasket of the new
filter with clean engine oil.
5. Reinstall the oil drain bolt
and tighten it securely (see
page 5).
6. Screw the new oil filter on
by hand until the gasket
contacts the filter base, then
use an oil filter wrench to
tighten the filter 7/8 turn.
Oil Filter Torque: 15-17 ft-lb (20-24 N•m)
NOTICE
Use only a genuine Honda oil filter or a filter of equivalent quality
specified for your model. Using the wrong Honda filter or a non-
Honda filter which is not of equivalent quality may cause engine
damage.
7. Add the specified amount of the recommended oil (see page 5).
Start the engine and check the filter for leaks.
8. Stop the engine and recheck the oil level. If necessary, add oil to
bring it up to the proper level.

AIR CLEANER

A dirty air cleaner will restrict air flow to the carburetor and cause poor
engine performance. Inspect the filter each time the engine is
operated. You will need to clean the filters more frequently if you
operate the engine in very dusty areas.
NOTICE
Operating the engine without a filter, or with a damaged filter, will allow
dirt to enter the engine, causing rapid engine wear. This type of
damage is not covered under the Distributor's Limited Warranty (see
page 11).
Inspection
1. Remove the wing nut, then
remove the air cleaner cover.
Be careful to prevent dirt and
debris from falling into the air
cleaner base opening.
2. Remove the air filter from the
air cleaner base.
3. Remove the foam filter from the
paper filter.
4. Inspect the paper and foam
filters. Replace damaged filters.
Clean or replace dirty filters.

Cleaning
1. Remove the air filter, as described in the INSPECTION procedure
(see page 6).
2. Remove the air filter from the air cleaner base. Remove the foam
filter from the paper filter.
3. Paper filter: Tap the paper filter several times on a hard surface to
remove excess dirt, or blow compressed air [not exceeding 30 psi
(207kPa)] through the paper filter from the inside out. Never try to
brush off dirt; brushing will force dirt into the fibers. Replace the
paper filter if it is excessively dirty.
4. Foam filter: Clean in warm, soapy water or nonflammable solvent,
rinse and dry thoroughly. Do not use gasoline as a cleaning solvent,
because that would create a risk of fire or explosion. Dip the foam
filter in clean engine oil, then squeeze out all excess oil.
NOTICE
Excess oil will restrict air flow through the foam filter and may
transfer to the paper filter, soaking and clogging it.
GASKET
5. Wipe dirt from the air cleaner base and cover using a moist rag. Be
careful to prevent dirt from entering the air duct that leads to the
carburetor.
6. Reinstall the air filter, and make sure both foam and paper filters are
properly positioned. Install the air cleaner cover and tighten the
wing nut securely.
Cooling Air Filter Cleaning (LPG models)
The air filter surrounding the recoil
assembly keeps the engine cooling
system clean. The air filter must be kept
clean so that the engine cooling system
operates efficiently.
NOTICE
If the air intake filter is not cleaned regularly, or if the engine is
operated without the air intake filter, the engine may overheat and
engine damage may occur.
1. Remove the cooling air filter and clean in warm, soapy water.
2. Dry the cooling air filter thoroughly and reinstall it.

SPARK PLUG

Recommended Spark Plugs: NGK BPR5ES
The recommended spark plug is the correct heat range for normal
engine operating temperatures.
NOTICE
Incorrect spark plugs can cause
engine damage.
For good performance, the spark
plug must be properly gapped and
free of deposits.
1. Disconnect the cap from the
spark plug, and remove any dirt
from the spark plug area.
2. Use a 13/16 inch (21 mm) spark
plug wrench to remove the spark
plug.
