    96GSX 80psi per cylinder

    I have a 96 GSX that runs great on the trailer but when I put it in the water it won't go past 4500 rpm and is very sluggish out of the hole. I did a compression test and only got 80psi on each cylinder. The manual says 140 to 150psi could this be my problem and also am I looking at a rebuild?

    use a different guage and see if it reads the same. If it does, you may be correct. How does it idle?

    The ski starts up just fine and idles fine. I will try and find another tester and do a comparison.

    Sounds like it may be top end time. Try another gauge, it is slightly odd that both cylinders are reading exactly 80 psi. I rarely ever seen two cylinders that weren't off by a few psi. Maybe your gauge is sticking...

    Top end rebuild isn't as terrible as it sounds.

    What am I looking at for price for a top end rebuild. Are there any good online tutorials for it.

    Did you hold the throttle wide open while cranking and was the battery fully charged.

    Battery is good but I didn't hold the throttle wide open. Can that make a different?

    I was looking at fullboreonline.com has anyone dealt with them before or have any suggestions on where to get a kit from and have my cylinders honed.
