
To service cylinder, see Servicing Top-Side Compo-
nents sub-section.
CAUTION
When removing the cylinder, be sure to support the pis-
ton to prevent damage to the crankcase and piston.
16. Using an awl, remove one piston-pin circlip.
17. Using the Piston Pin Puller, remove the piston pin.
Account for the opposite-side circlip. Remove the pis-
ton.

NOTE: It is advisable to remove the opposite-side
circlip prior to using the puller.

NOTE: Support the connecting rod with rubber
bands or a piece of hose to avoid damaging the rod
or install a suitable connecting rod holder.
CAUTION
Do not allow the connecting rod to go down inside the
crankcase. If the rod is down inside the crankcase and
the crankshaft is rotated, severe damage will result.

Servicing Top-Side
Components
VALVE ASSEMBLY
When servicing valve assembly, inspect valve seats, valve
stems, valve faces, and valve stem ends for pits, burn
marks, or other signs of abnormal wear.

NOTE: Whenever a valve is out of tolerance, it must
be replaced.
Cleaning/Inspecting Valve Cover

NOTE: If the valve cover cannot be trued, the cylin-
der head assembly must be replaced.
1. Wash the valve cover in parts-cleaning solvent.
2. Place the valve cover on the Surface Plate covered
with #400 grit wet-or-dry sandpaper. Using light pres-
sure, move the valve cover in a figure eight motion.
Inspect the sealing surface for any indication of high
GZ145
spots. A high spot can be noted by a bright metallic
finish. Correct any high spots before assembly by con-
tinuing to move the valve cover in a figure eight
motion until a uniform bright metallic finish is
attained.
Do not remove an excessive amount of the sealing sur-
face or damage to the camshaft will result. Always
check camshaft clearance when resurfacing the valve
cover.
GZ146A
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.
Removing Valves

NOTE: Index all valves, springs, and cotters to their
original position when removing. When installing, all
valve components should be installed in their origi-
nal position.
1. Using a valve spring compressor, compress the valve
springs and remove the valve cotters. Account for an
upper spring retainer.
