Air Cleaner; Spark Plug - Honda GS160 Owner's Manual

Oil Change
Drain the engine oil when the engine is warm. Warm oil drains quickly
and completely.
1. Place a suitable container
next to the engine to catch
the used oil.
2. Remove the oil filler cap/
dipstick [1] and the oil drain
plug [2].
3. Allow the used oil to drain
completely, then reinstall the
drain plug [2] and washer
[3]. Tighten the drain plug
securely.
Please dispose of used motor oil in a manner that is compatible
with the environment. We suggest you take used oil 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.
4. With the engine in a level position, fill to the upper limit mark
(bottom edge of the oil fill hole [4]) on the oil filler cap/dipstick [1]
with the recommended oil (see page 5).
NOTICE
Running the engine with a low oil level can cause engine damage.
5. Reinstall the oil filler cap/dipstick [1] securely.

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 filter more frequently if you
operate the engine in very dusty areas.
NOTICE
Operating the engine without an air 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.
Inspection
1. Press the latch tabs
[1] on the top of the
air cleaner cover [2],
and remove the
cover.
2. Remove the foam
element [3] from the
air cleaner cover.
[5]
3. Remove the grid [4]
from the paper
element [5].
4. Check both
elements to be sure
they are clean and
in good condition.
5. Reinstall the grid
over the paper
element. Make sure that the grid completely surrounds the paper
pleats.
6. Reinstall the foam element in the air cleaner cover.
7. Set the paper element and screen grid in the air cleaner body then
install the air cleaner cover

Cleaning
1. Tap the filter [5] several times on a hard surface to remove dirt, or
blow compressed air [not exceeding 30 psi (207 kPa, 2.1 kg/cm²)]
through the filter from the clean side that faces the engine. Never
try to brush off dirt. Brushing will force dirt into the fibers.
2. Foam Element [3]: Wash the element in a solution of household
detergent and warm water, then rinse thoroughly, or wash in
[1]
nonflammable or high flash point solvent. Allow the element to dry
thoroughly.
Soak the element in clean engine oil and squeeze out the excess
oil. The engine will smoke during initial start-up if too much oil is
left in the foam, or the oil could saturate the paper element making
[2]
the engine inoperable.
3. Wipe dirt from the air cleaner body [6] and cover using a moist rag.
Be careful to prevent dirt from entering the air duct [7] that leads to
the carburetor.

SPARK PLUG

Recommended Spark Plug: NGK BPR6ES
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 the proper size spark
plug wrench [1] to remove
the spark plug.
3. Inspect the spark plug.
Replace it if damaged, badly
fouled, if the sealing washer is in
poor condition, or if the electrode is
worn.
[2]
4. Measure the electrode gap with a
suitable gauge. The correct gap is
0.70 – 0.80 mm (0.028 – 0.031 in).
If adjustment is needed, correct the
gap by carefully bending the side
electrode.
5. Install the spark plug carefully, by hand, to avoid cross-threading.
[3]
6. After the spark plug is seated, tighten with the proper size spark
plug wrench [1] to compress the washer [2].
[4]
7. When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.
8. When reinstalling the original spark plug, tighten 1/8 – 1/4 turn
after the spark plug seats to compress the washer.
NOTICE
A loose spark plug can become very hot and can damage the
engine. Overtightening the spark plug can damage the threads in
the cylinder head.
9. Attach the spark plug cap to the spark plug.
