Measuring the gxv120 Cylinder Bore

After I got the gxv120 cylinder honed I began to have doubts that the cylinder was still within spec. After all, this engine is pushing 30 years old (!), and was running super high revolutions when the tear-down began. So I decided to do some rough measurements with a telescopic bore gauge and calipers that I borrowed from a friend. Luckily the hr214 shop manual had the specs for the bore, and after taking some measurements it looks like my bore has about .05mm of wear, but is still well within spec. If anybody wants to do a tear down on one of these hondas and take the measurements, you need to take your time and do multiple measurements. I followed the directions from the video below:

Tools used in video:

Telescoping Bore Gauge Set

Digital Caliper

Dial Bore Gauge

Like Jaf says in the video, the dial bore gauge is the best solution if youre building a serious engine, b ut for a lawnmower engine that is measuring so far below tolerance with the telescoping bore gauge set, I think Im fine. I ordered some parts from boats.net too...hopefully next week the rebuild will start.
