I thought my Suzuki was Katana, not a Vitara!

  1. I bought a '97 Suzuki Katana from a guy, who, I really shouldnt hav
    bought a '97 Suzuki Katana from. But anyways...

    I have been plauged with a number of problems, but a very interestin
    one is the fact that it is redlining nowhere CLOSE to where it shoul
    be. Instead of 13K (I believe, it has a digital tach) it will redlin
    around 6K, and around 5400 it feels like it is going to vibrate it'
    self out of the frame...

    This is kind of a problem considering it is designed for higher revs
    and at 6/7 grand it will smoke if I rev it up there.

    I am new to motorcycle repair, but I am really trying to learn an
    understand my bike better. So if you have any ideas, let me know.

    And yes... I ran Berryman's B-12 through it :

    One would certainly hope that B-12 had cleared out the idle mixture
    circuits, but it's possible that there is still crud up in the
    passages. Some of the stuff that plugs up the carburetors is like
    calcium carbonate, it's a mineral that hydrocarbon solvents won't

    Plugged jets and passages would be indicated by the exhaust going
    "piffle-piffle-SNAP!" or even "fart-BANG!" as you roll the throtte off.

    Other possibilities are crossed up spark plug wires, dirty spark plugs,
    and dirty air cleaner.

    What do the spark plugs look like? Maybe it's past time for new ones.

    Have you tried running the engine without the air filter to see what

    Have you checked the compression with the engine hot? Low compression
    would keep the engine from developing a lot of power. Crud build up on
    the intake valves would keep it from inhaling and compressing fresh
    mixture, worn rings or worn out valve guide seals would make the engine
    smoke. The worn out valve guide seals would cause the engine to smoke
    especially at start up.

    High vibration and low rpms could be symptoms of running on 3 cylinders.
    While you can get information about this possibility by looking at the
    plugs, it's probably worth checking to see whether all four headers get
    hot, as that's quick and easy.


    'indiana' is a 'nolnn' and 'hoosier' is a 'solkk'. Indiana doesn't solkk.
