Rather than the dial bore gage Kevin looked at, you can make this
measurement accurately with a 3"-4" micrometer ($35 from Enco) and a
telescoping gage (set of 5/16"-6" is $13 from Enco). As with the dial gage,
accuracy will depend on your care and skill in making the measurement
exactly perpendicular to the bore (hint : use an old piston as a reference)
and on-center. But it should be easy to achieve .0005", more than the
necessary accuracy for just a wear indication.
Or, use the micrometer to measure an old piston, then a feeler gage to
compare the bore diameter to the piston diameter.
