Compression Test Results???

Yes I did a search but everyone is asking about there numbers on engines that aren't even broke in. I have a rebuild w/ about 40k on it and here's my numbers: front rotor 7.2/7.4/7.4 and ther rear 7.2/7.4/6.5. Compression test was done warm. Not exactly sure what I should get from this. Is this good? Would appreciate some input from somethat knows. Thanks

7.0 is about 100 psi (average @ 250rpm) However, your front rotor seems even across the board... but It`s the 6.5 in the rear rotor that questionable.

You probably have a sticking side seal...mix 8oz of Marvil Mystery Oil to a tank of gas to try and loosen it up, the recheck you compression after some miles of driving.
