Quote from: Icarus on March 30, 2023, 11:09:49 PMI was thinking of one of those occasions earlier today. It was about one of my race motorcycles a long time ago...like 60 years ago. That bike was spectacular and it won every race that it entered. I decided to give it a little extra maintenance. I will give it a new piston and attend to the valves or any other part as needed. I sent the cylinder out to a machine shop to have it bored for the new oversize piston. It was a German bike and I had the service manual and also some direct advice from the factory. The proper piston clearance was 0.10 mm. I told the machine shop to bore to fit that spec. They told me that they figured that was too much clearance. I said "no use that dimension". They bored it 0.010 inches for the piston clearance. The engine was a poor performer immediately after that, until I discovered, to my extreme humiliation, that the damned piston was flopping around in the cylinder. Ten thousandths is two and a half times one tenth millimeter.Why I was thinking about that this morning I cannot know. Actually this small episode was a result of my own stupidity which caused me much humiliation. I knew the difference between metric and Imperial measure but failed to make the important distinction to the machine shop. That was 60+ years ago and metrics were not a common unit of measure in the US, at the time.
