    fouling rear plug

    My buddy has an '01 gpr1200. It was running good today in the ocean then it started to act up & was fouling the rear plug. he put new plugs in & it was wet & black after 15 minutes too. Any Ideas what this might be?

    Stinger3
    riva heads 150psi
    F/A's & rejet
    water bypass
    solas 13/20
    stock grate
    R&D ride plate & tabs
    ppk

    All work was done by racers edge & it was fine last week on a 90 mile river run & most of today. You think maybe the wave jumping loosened something up?
    All I know is both my seadoo's ran flawless.

    J/K.....he's been through a lot of down time with this ski & he thought it was all good.... till today.

    But really, don't take the seadoo thing serious.

    Probably needs a rear carb re build or water may be getting into the rear cylinder.

    Definitely the rear carb, it may not even need rebuilt. Because of the accelerator pump mount, the rear carb diaphram cap is billet alloy, not tin as are 1 and 2 carb caps. With salt use and a lack of engine bay cleaning and or engine bay ventillation, the relief or bleed hole blocks, hence you get sporradoc fuel feed to no 3. I truly believe that this is the main reason that no 3 cylinder fails most often. It is possible with a mirror, torch and a 1/8in drill bit to unblock this hole without dismantling, tedious and not recommended for the ham fisted person. REXA.

    situation resolved!
    He found the rear F/A (fly's) was messed up. The center cone dropped & was choking the carb. He also found that the front one was ready to drop too. Middle is solid.. He got lucky..

    Thanx for the replies.
    Tim, you missed a perfect riding day.
    here's some clips from my "secondary camera"...My good one is in the shop.

    Right click & "save as" or if you have the time just run it from the server.
