Cleaning and Inspecting
CYLINDER HEAD
1. Using a non-metallic carbon removal tool, remove
any carbon buildup from the combustion chambers
being careful not to nick, scrape, or damage the com-
bustion chambers or the sealing surfaces.
2. Inspect the spark-plug holes for any damaged
threads.

NOTE: If warpage is suspected, have a qualified
machine shop inspect and repair if necessary.
4. Place the cylinder head on a Surface Plate covered with
#400 grit wet-or-dry sandpaper. Using light pressure,
move each cylinder head in a figure eight motion.
Inspect the sealing surface for any indication of high
spots. A high spot can be noted by a bright metallic fin-
ish. Correct any high spots before assembly by continu-
ing to move the cylinder head in a figure eight motion
until a uniform bright metallic finish is attained.
CYLINDERS
1. Using a non-metallic carbon removal tool, remove
carbon buildup from the exhaust ports.
2. Wash the cylinders in parts-cleaning solvent.
3. Inspect the cylinders for pitting, scoring, scuffing,
and corrosion. If marks are found, repair the surface
with the Ball Hone and honing oil.

NOTE: To produce the proper 45° crosshatch pat-
tern, maintain a low drill RPM. If honing oil is not
available, use a lightweight, petroleum-based oil.
Thoroughly clean the cylinders after honing using
detergent soap and hot water and dry with com-
pressed air; then immediately apply oil to the cylinder
bores. If a bore is severely damaged or gouged, the
cylinder must be replaced.
4. Place the head surface of each cylinder on the sur-
face plate covered with #400 grit wet-or-dry sandpa-
per. Using light pressure, move each cylinder in a
figure eight motion. Inspect the surface for any indi-
cation of high spots. A high spot can be noted by a
bright metallic finish. Correct any high spots before
assembly by continuing to move the cylinder in a fig-
ure eight motion until a uniform bright metallic fin-
ish is attained.
CAUTION
Water or parts-cleaning solvent must be used in con-
junction with the wet-or-dry sandpaper or damage to
the sealing surface may result.
