Spark Plug Service

Recommended spark plugs:

NGK – CM5H or CMR5H

NOTICE

Incorrect spark plugs can cause engine damage.

1. Loosen the captive 5mm hex bolt with a 4 mm Allen

wrench, then remove the fan cover.

2. Disconnect the spark plug cap, and remove any dirt

from around the spark plug area.

3. Remove the spark plug with a 5/8-inch spark plug

wrench.

4. Inspect the spark plug. Replace it if the electrodes

are worn, or if the insulator is cracked, chipped, or

fouled.

5. Measure the spark plug electrode gap with a

suitable gauge.

Plug gap: 0.024 ~ 0.028 in (0.60 ~ 0.70 mm)

Correct the gap, if necessary, by carefully bending

the side electrode.

6. Make sure the sealing washer is attached and

install the spark plug carefully, by hand, to avoid

cross-threading.

7. After the spark plug seats, tighten with a 5/8-inch

spark plug wrench to compress the washer.

If reinstalling the used spark plug, tighten

1/8 ~ 1/4 turn after the spark plug seats. If installing

a new spark plug, tighten 1/2 turn after the spark

plug seats.

NOTICE

A loose spark plug can overheat and damage the

engine. Overtightening the spark plug can damage

the threads in the cylinder head.

8. Attach the spark plug cap.

9. Install the fan cover, and tighten the 5 mm hex bolt

securely.
