    I just measured mine tonite, its a 2007 gpr that is brand new, only started for 10 seconds.

    Compression tested with a snap-on gauge

    1.....130 psi

    2.....133 psi

    3.....130 psi

    Remove the plug wires. Put the tester in one plug hole at a time leaving the other plugs in. Hold the throttle wide open. While holding the stop button push the start button and the ski will turn over without trying to fire. Watch the guage rise until it levels off (a few rotations). Its recomended to put the battery on a 2 amp charger while testing just to make sure its got plenty of juice however its not mandatory. Yes it is done on the trailer.
