    Unhappy 2001 GPR Hesitation/Loss of Power HELP?

    I have a 2001 GP1200R and the ski was fine before the season started I changed the plugs and they all seemed to be fine. I use only Amsoil Oil and last weekend I was out on the water I went to jump a wake and when I came down lost almost all power and it hesitates and starts fine but no power. Need advice and help do you think I fouled a plug or caught something in the pump.


    Mod's are intake grate, ride plated 05 pump,performance prop and reed stuffers.

    It had new gas and new plugs in the ski. Also how do I check the PV and what are they. The ski starts fine but on the water it will go but no full power.


    Thanks for all the help.

    I would say maybe powervalves but I don't know too much about them. I have efi. Do a search on how to check them. If thats not it I am thinking the impact of landing after hitting the wake may have knocked something loose. Check all hoses and electrical connections

    You can hear the PV's cycle when you attach the lanyard and bump the start button. If you dont hear anything its not operating..


    Answer this question that was asked earlier...
    no power at all or does it kick in at higher RPM's?

    Thumbs up

    Changing plugs today and a local greenhulk member came over yesturday and he showed me how to check the PV and they are ok. As for the plugs when we removed them my friend said I fouled one out and I should change them then see if that fixes the problem.


    As for answering the ? it would run and when I would squeze the triger it just would not go any faster.
