    what should the compression be on a 95xp with a 720 in it?

    150/155 psi is about right for the 720 motor

    Around the 150 mark is good. Lower readings dont necessarily mean anything bad. What you do want is that both cylinders readings are close to each other. A 10% difference is not uncommon, but dont recommend allowing larger differences unless you thoroughly check condition of cylinders/pistons.
