I added this tool to my tool kit so that I wouldn't have to rely on a friend for measuring cylinder bores. It finally arrived today and I've been trying to figure how to use it. The instructions are the worst I've ever seen for anything. Just a couple of sketches to illustrate what it should look like. No actual instructions on how to use it. Their website is just as bad. So I'm looking for help on whether I'm using it correctly.
This is a photo of the gauge. I'm trying to measure a KZ650 cylinder bore with a spec of 2.4407 " to 2.4411 ", with a limit of 2.4449 ". I am using a 2.362 " probe with a 0.08 " washer, giving me a measurement diameter of 2.442 " The gauge is a bit tight, as expected. In fact I think the gauge always had to be a bit more than the bore in order to get a good measurement.
The dial indicator was zeroed with the small gauge on 0.05 " and the outer dial on 0.0000 ".
Once in the hole the gauge measured minus 0.069 ". When I subtract this from the total gauge probe length I get 2.373 ". This is well under the spec so I assume I've done something incorrectly.
Last photo shows the gauge instructions....Item 4 in the photo. Nothing specific, just some illustrations to show how to calibrate etc.
Does anyone know how this thing should work?
