    Bogging down when turning ?

    I just took out my 99 gp1200 for the first time this year.. and it starts up right away, sounds good, but when not at full throttle it boggs down, and it also does the same thing when taking sharp turns, it takes a few sec to come back to full throttle after that.. also i noticed on perfect flat water it tops out at only 54mph, it is stock, but i remember it going faster then that. Just ran compression, 110 +-1 on all three, plugs look ok i think (pics included). What should i look at next? Fuel is fresh, oil lines all checked.

    Well i cleaned out the main fuel filter, double checked all the hoses and cables.. took it out again, when its cold it runs good, but when i run it for a longer time it starts giving me more problems.. Any input? i might take the carbs apart.. tho i have never done anything like that, not sure if i will notice if something is not right.. i have a manual i guess we will see what happens

    Ok, so i took apart the carbs... if anyone can help me, i noticed two things that don't seem right, on the same carb, i included pictures, but in the first pic, the plastic seems pretty warped, and it pops in and out when pushed... the 2nd pic, the small plastic has some damage, like its pushed in, hopefully you can see it in the picture... I really can't afford a carb rebuild right now but if this is deff whats causing my hesitation problems then i guess i have no choice.. any input?

    Both are an issue...you need a new gasket on the pump cover...new plastic clear and change the check valves. You can contact John at Jet ski soultions and he can sell the specific parts
