Service procedure

Inspection before disassembly
(1) Extent of piston protrusion from the upper surface of
crankcase

NOTE
Always inspect the extent of piston protrusion because it af-
fects the engine performance greatly.
• Measure piston protrusion at two points on the top of the piston, and
produce the average value.
A : Front of the engine
• If the average valve deviates from the limit, inspect clearance of the
related parts.
