    Results of compression test

    I just did a compression test and got 117 on all cylinders, what do you think. That was on the 03 gp1300 by the way.

    I like the consistency! and it might be a tad low ? however it might be the gauge? how it runs is more important! Z

    What is ideal compression for a Stock GP1300R? I have used the search function and seem to get a lot of different answers.

    03-04 1300 is 120-120-115 at sea level, The 05 and up 1300 is 5 psi. higher.

    Every guage reads a bit different, the good thing is they are all consistent. Ride it like you stole it!

    i just did a compression test on my 03 gp1300r and got 100 psi for each cylinder. this is well below the 120 psi which it should be. what would cause this? worn piston rings?

    there is a few possibilities, one being did you hold your throttle wide open when you did the test? is your gauge reliable, in my experiences, the cheap gauges from auto stores dont work well.

    My 2001 Gp1200r has 110 psi on all three. Is this alittle low or does the 1200's have lower compression the the 1300's?
