Why is it all these threads turn into while we do this here We do that there What the **** man If it if there isn't an issue and you got good compression Just move on nobody needs to show how big their ****ing ***** are You guys got to get a grip it doesn't ****ing matter these are ****ing Harleys.. They're not a technical instrument or nothing You give them gas and go down the road as long as they run halfway decent everybody's ****ing happy....

Back on topic I was under the impression that a leak down test is only done after a normal compression test has showed low readings, and the purpose is to decide if the compression is lost through the piston rings or the valves.
The ring to cylinder seal during real engine running is improved by the compression pressure pushing the compression rings outwards against the cylinder walls, this effect is not present during a leak down test so its only natural that there is some leakage.

All I use it for. My gages aren't calibrated, other then me adjusting it in the beginning set up for pressure. Most manuals I have only show cranking,warm motor and wide open carb or throttle body .
Appears now in the aircraft certificate, there OK but I guess everything they use like torque wrenches ect are certified.
Were I use to work, we built nuclear subs. Ever thing we used was calibrate to 10 times the working tolerance.
It was nothing unusual to see most torque wrenches fail that when they came in brand new . Most, we just destroyed. Sometimes, manufacturers wanted them back if the were the big ones.
Most all ended up requiring a dial type.

I'm still trying to figure out what pissed him off here.. Now the vernier caliper thing I could see.. I once sent a buddy a dial caliper because all he had was what he called a cheap vernier caliper.. Turned out he was talking about a dial caliper but called it Vernier. Personally, IMO, a good vernier is likely more accurate than a dial..

I'm glad you see the humor in it, even when I look back I laugh as well... Lol...
Don't get me wrong here Max I respect your knowledge but sometimes you seem to needle people too much and provoke them and sometimes if I have a few beers I say stupid ****.. lol.. that's all.. I'm kind of the same way cuz even at work a lot of people don't like me cuz I'm too **** but I like to be precise as well so actually I should respect you even more for that... And here's your favorite smiley face... ....
It's not just his vocabulary It's his way of thinking and honestly I believe that's the way he is..I mean he's a machinist... And only to the 10/100000".... .... Green with envy...
