With the micrometer set to the piston dimension,
adjust a cylinder bore gauge to the micrometer
dimension and set the indicator to 0.

1. Indicator set to 0 (zero)
IMPORTANT: Always remove cylinders from
crankcase before measuring.
Position the dial bore gauge at 16 mm (5/8 in) be-
low cylinder top edge.

1. Measuring perpendicularly (90°) to piston pin axis
A. 16 mm (5/8 in)
Read the measurement on the cylinder bore
gauge. The result is the exact piston/cylinder
wall clearance. If clearance exceeds specified
tolerance, replace cylinder or rebore and install
oversize piston depending on engine type. Refer
to TECHNICAL DATA.
NOTE: Make sure the cylinder bore gauge indica-
tor is set exactly at the same position as with the
micrometer, otherwise the reading will be false.
IMPORTANT: The total piston/cylinder clearance
(actual cylinder diameter minus actual piston skirt
diameter) should be within 0.30 mm (.012 in).
