    carb tuning issues

    Im having a hard time reading my plugs.
    I was told by a realiable source that I possibly have an air leak?

    My plugs looked pretty fouled so I tached it on low speed and turned my low scre in 1/2.

    At first they both looked rich but in opposite parts of the plugs, after a few hours of riding they both looked real foul.

    after installing new plugs, after five minutes, the rear one looked rich and the front one looked lean but now....



    Im at 1 1/8 turn out on my Kehien 38 (stock jets) for my x2
    The rear plug (pto) looks a bit lean but the front one (mag side) looks a bit rich. -- the pictures are after about 10 minutes of riding at 2/3 of the thottle most.

    Im perplexed, what do you guys think?

    looks like an air leak to me as well. Try firing up the ski and spraying starting fluid around the lean carb and any suspious areas where a airleak may be. Try areas where you may have just done work on. If it revs up when you spray near it, theres your leak.
