    Gp1200r 110psi too low?

    Took the gp1200r to pier 47 in wildwood nj. Was told compression was 110 in all three cyls and was a tad low but Ok. Ski works fine, but I am wondering if I should do a rebuild or just keep riding? I am not really worried about performance but am concerned about reliability. Would doing a topend mean less chance of failure down the road?

    Ski has 125 hours.

    Welcome to GH,personally,if it aint broke and you say it still runs fine,dont try fix it,just my opinion.110psi is ok if they are the same across all 3,there are many factors to consider when compression testing,there is loads of info on here to help you,search and learn,and trust me,there is alot to learn.Btw,it's a 2 stoke and you are now a member on here so the chances that it will be stripped down at some point are pretty good.

    I'm not a pro but 110 psi sounds really good for a ski with 125 hours on it.
    If you are concerned about the reliability of your ski make sure everything regarding your oil mix is intact (pump, lines etc.)
    If I were you I would switch to premix to eliminate one cause for a future failure but let's wait what the pros recommend.

    Thank you for the welcome. I've been reading this site a lot since last year so I do know what to expect. I've done the D-plate, PV clips, oil pump removal. I get freaked out reading about the problems people have because I ride alone in the ocean sometimes and don't want to get stuck out there .

    But I have found a hobby in dealing with 2strokes, although I really haven't done any motor work yet. So for now I will leave a working ski alone and keep on riding.

    110 is fine/normal across all 3 on a stock 1200 motor.
