Im gettin ready to do a compression test on my raptor. Does it need to be warmed up first? And when I'm doing the compression test do I have to hold it WOT? Is there anything else I need to know or do?
Thanks

No the Raptor doesn't need to be warmed up. Just make sure that no air is escaping the compression gauge (i.e. make sure you have a tight seal on all of the gauge's connections). Yes you do need to hold the throttle wide open when you perform the test. :)

Ok, Thanks.

I went to do the test and dont have the right adapter for my tester. What size is it? 12mm? The smallest one I have is 14mm and its a little too big. Where could I get the right size one? I tried autozone and a couple different hardware stores and they didnt have anything.
