    hello,

    How do you know if your bike is running too lean? I've heard that you could end up with holes in your pistons...Will a dino test tell me?

    Welcome! What Model and year bike are we talking about?
    Modifications?
    Your gonna know you've got a problem way before you burn a hole in a piston. When you accelerate is it smooth or ruff with popping and backfiring? Spark plugs will be the easiest to read at home, they should be a light tan color, Black is rich, white is lean.
    And yes a Good Dyno Tuner can use a Dyno to tell if your motor is lean.

    PC is absolutley correct. Look at your plugs, they will tell the story: white is lean, juicy black is rich and heroin light brown is correct.
