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.
3. 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.
CAUTION
DO NOT drive any tool between halves (sealing surface)
to separate the crankcase. Damage to the sealing sur-
faces will result.
CAUTION
Care must be taken to not allow the connecting rods to
drop onto the sealing surface of the bottom case half.
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.
