CYLINDER / PISTON REMOVAL

CAUTION
Pistons must be removed from the cylinders with the
connecting rods attached.
DO NOT attempt to service the cylinder or pistons
without disassembling the crankcase. Although you can
remove the cylinder and pistons without disassembly,
you will not be able to reassemble the engine because
of the unique cylinder skirt and crankcase design.
1. Perform "ENGINE DISASSEMBLY / INSPECTION -
TOP END" and the "ENGINE DISASSEMBLY /
INSPECTION - LOWER END" procedures.
