FLYWHEEL BRAKE Inspection (applicable types)

Check the flywheel brake lever clearance. If it is less than 2 mm (0.08 in),
take the engine to an authorized Honda dealer.
See Figure 11, page A-3.

SPARK PLUG

See Figure 13, page A-4.

Recommended Spark Plug:

BPR5ES (NGK)

The recommended spark plug has the correct heat range for normal
engine operating temperatures.

An incorrect spark plug can cause engine damage.

If the engine has been running, let it cool before servicing the spark plug.

For good performance, the spark plug must be properly gapped and free
of deposits.

1. Disconnect the spark plug cap, and remove any dirt from around the

spark plug area.

2. Remove the spark plug with the spark plug wrench.

3. Visually inspect the spark plug. Discard the spark plug if there is

apparent wear, or if the insulator is cracked or chipped.
Clean the spark plug with a wire brush if it is to be reused.

4. Measure the spark plug electrode gap with a feeler gauge. Correct as

necessary by bending the side electrode.

The gap should be:

0.7–0.8 mm (0.028

–

0.031 in)

5. Check that the spark plug washer is in good condition and thread the

spark plug in by hand to prevent cross-threading.

6. After the spark plug is seated, tighten with the spark plug wrench to

compress the washer.

When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.

When reinstalling a used spark plug, tighten 1/8–1/4 turn after the
spark plug seats to compress the washer.

TORQUE:

20 N∙m (15 lbf∙ft, 2.0 kgf∙m)

A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the cylinder
head.

7. Attach the spark plug cap to the spark plug.

SPARK ARRESTER (applicable types)

In some areas, it is illegal to operate an engine without a spark arrester.
Check local laws and regulations. A spark arrester is available from
authorized Honda servicing dealers.

The spark arrester must be serviced every 100 hours to keep it
functioning as designed.

If the engine has been running, the muffler will be hot. Allow it to cool
before servicing the spark arrester.

Spark Arrester Removal

See Figure 14, page A-4, Figure 15, page A-4 and Figure 16, page A-5.

1. Remove the screw and spring nut.

2. Remove the fuel tank cap.

3. Remove the top cover by unhooking the four tabs of the top cover.

4. Remove the muffler protector by removing the three 6 mm bolts.

5. Remove the spark arrester from the muffler by removing the screw.

(Taking care not to damage the wire mesh.)

Spark Arrester Cleaning & Inspection

See Figure 14, page A-4, Figure 15, page A-4 and Figure 16, page A-5.

Check for carbon deposits around the exhaust port and spark arrester,
and clean if necessary.

1. Use a brush to remove carbon deposits from the spark arrester

screen. Be careful not to damage the screen. Replace the spark
arrester if it has breaks or holes.

2. Install the spark arrester, muffler, top cover and fuel tank cap in the

reverse order of disassembly.
