I have not done one in a while but it should be around 90 psi. I may be wrong

125 cranking compression in 3 cycles....
although the test will only show pressure...to check the actual cylinder health you need to do a leakage test...

the important thing is that they are all pretty even. say 90, 95, 85 and so on and so on. if you have 125 in a couple and one or two have 80 then you have some thing wrong.
