    2012 RXP-X compression numbers?

    What should the compression numbers be on a 2012 RXP-X 260 with 39 hours on it?

    Should I test it cold with the other two spark plugs in place?

    i always do just the plug out of the cylinder im testing and the others left in, throttle heald wide open. again though everyone does it a little different, just make sure you do it the same way each time (same gauge, plugs in/out etc) you do it so you're comparing like-for-like numbers

    Thanks! I will do that today. Cheers for the reply.
