Section02ENGINE

Subsection 09 (ENGINE MEASUREMENT)

A35C2YA

1. Top of spark plug hole

NOTE: The liquid level in cylinder must not drop

for a few seconds after filling. If so, there is a

leak between piston and cylinder. The recorded

volumewouldbefalse.

– Let burette stand upward for about 10 minutes,

until liquid level is stabilized.

– Read the burette scale to obtain the quantity of

liquid injected in the combustion chamber.

NOTE: When the combustion chamber is filled to

top of spark plug hole, it includes an amount of

2.25 cc corresponding to the spark plug well.

– Repeat the procedure for the other cylinder.

– Install a thicker or thinner cylinder/crankcase

gasket (refer to Parts Catalogs)inordertoob-

tain the specified combustion chamber volume

or the nearest.

USED PISTON MEASUREMENT

Note the measurement on the piston dome.

F00D0EA

2 1

1. Piston dome

2. Piston measurement

Using a micrometer, measure piston skirt at

29 mm (1.142 in) perpendicularly (90°)topiston

pin.

A35C2ZA

1. Measuring perpendicularly (90°) to piston pin axis

A. 29 mm (1.142 in)

The measured dimension must not be less than

0.15 mm (.006 in) of the one scribed on piston

dome. Otherwise, replace piston.
