    Balance shaft oil....

    As mentioned before I have a 96 and 97 GSX. The 97 has an oil inspection port that allows you to ad oil to the balance shaft on the engine. Now the 96 does not have that option BUT I do see a plug that resembles an automotive frost plug. Can this plug be removed? The dealer says no and tells me the only way to ad oil on the 96 is to take the engine apart. Has anyone else come up with a way to tap or remove the plug on the 96 787?
    Sorry for all the newbie questions.

    You dont ever need to add oil to the 800 motor,it gets its lube from the gas oil mix as the rear cly area is directly connected to the balance shaft cavity.

    Ok... now I am REALLY confused (see it does not take much) ... the factory service manual states the following for the 50hr service:

    SPX, GSX, GTX and XP Models
    On the 787 engine, remove the drain plug of the
    counterbalance shaft located on the PTO side of
    the lower crankcase.
    Drain completely the crankcase oil of the counterbalance
    shaft. Reinstall drain plug.
    Remove the filling plug located on the upper
    crankcase.
    Add 30 mL (1 oz) of SAE 30 motor oil.
    Reinstall filling plug.

    The problem I have is the 96 does not have the fill plug like the 97 does.
    Where the fill plug is there is a cap that resembles a frost plug.

    The fill plug, 97 and above 800's have them.
    There must be a good reason for putting these on the later model 800 engines.

    HOLY CRAP.... That engine shown at the end of the page is enough reason to change the later 800s...There has got to be a way to tap that plug in the 96...

    If any of you even knew what you were talking about.

    I have probally built more 800's than all you guys ages added together.

    Go ahead & add the oil & make sure you take some extra spark plugs to replace all the plugs that foul on the rear cly.

    I guess if this was PWCToday, we could have a two week debate about it,
    get LisaLisa involved who knows crap about engines, and send someone to the MU list.

    The engineers didn't have anything better to do one day and decided to put a fill plug on there, spacey engineers.

    I've never blown a rear plug out, because of the balancershaft oil. Like I said between all you know it all tuners over at pwctoday, saying otherwise will get someone mu'ed.

    An ounce of oil is going to foul spark plugs, gimma a break. I just checked and filled that cavity, I'm going riding tomarrow, I'll let you know if I foul the rear plug.

    Read the first 4 lines of Seadoo sources statement.....

    If oil can leak out & get burned the oil can also leak back in.

    The gear is lubricated by the same oil that lubes the crank bearings,so adding oil is a total waste of time & effort,it will simply smoke a LOT more till its burned off & then your back to where you started from.

    Geez ease up there Mr. Water Worx....I do appreciate the fact you took the time to reply .....It ain't like I called you out on this...
    The factory service manual has that as a part of its tech service. So to me that has some merit to it. Just want to protect the $$ that I have tied up in these things as best I can. I did ad the 1oz to the 97 and no problem with the plugs fouling.
