    19 VX Cruiser HO -- Plugs too clean

    I'm new to 4 stroke skis, so wanted to get some inputs on the plugs in my 19 VX Cruiser HO.
    I pulled the plugs during the 10-hour maintenance and they were really clean.
    I expected them to be at least a little brown, but they were white.
    This would indicate a much too lean on a 2-stroke.
    Is this normal for 4 strokes?


    One thing I did learn, there is a place to grease the drive shaft housing bearings--it's hiding under the electrical box.

    On my 1.8na engine, they just have a very light beige color to them but that's usually at the 50 hour mark. How did you run the engine before pulling the plugs? This will change the way they look.

    They look perfect. They only have 10 hours on them. And the strap is not white.

    them things look great to me. 4 stroke plugs don't read like the old days of 2 smokes.

    Ran the engine with the flush line attached -- Mostly at idle to warm it up for the oil change.

    Thanks for all the comments. Haven't been on the forum for a while due to some family stuff that was going on.
    Ski is running well after the 10-hour service. Took my grandson for a ride last week and we did circles for what seemed like hours.
    He's 7 and loved making waves and jumping over them--as long as they were not too tall. Nothing better than the laughter of a little one having the best time of their life.

    When you change plugs....always once you have the coils off use compressed air and blow out the spark plug wells. The coil boots are not waterproof. If you rinse thoroughly like you are supposed to do....water collects in the wells. When you remove the plugs that bit of water ends up in the cylinder. First time you see it you will think you have a leaking head gasket! Happened to me the first time....lol!

    I have ridden 3 seasons on my stock plugs. Did first service at 8 hours (oil/filter) and did not bother checking the plugs. Units only have 31 hours on them. Will change the plugs out on the 50 hour service in the spring. These 1.8 n/a are pretty bullet proof.
