    Noises.

    I Think I rode it with to much throttle and damaged the engine.

    full throttle for 3 miles... now its broken )": .I'm an idiot, I thought it would be fine with full throttle because thats how I rode my 2 stroke alot and had no problems.


    And when you pull the bull start you here a a slight whining metal sound

    Eh, I ride WOT all the time with nary a trouble.

    Figure out what's making the noise, and we'll go from there.

    You have a pull starter on it ? Does it sound like its coming from that area ?

    Use a screw driver with the plastic end against the bone right in front of your ear. It works like a stethoscope. The find where the noise is coming from. Take it apart, find the offending broken goodies, and repair/replace. I doubt running it wide open for 3 miles broke anything major, especially on a four stroke. I'd bet it's something like the pull start, flywheel, or something non "lethal".

    I took the pullstart off and under it there's a thing that it turns(fly wheel?), I turned it by hand and it feels like it may be slipping a little and it makes a eeeeeeek sound. Anyone have any idea what it may be.

    I have warranty, but before I resort to sending it back I was hoping there is something I could so to maybe fix it

    The bike is fixed. The problem was one of the springs on the clutch snapping. I replaced it with a spring from the broken engine, now its working perfectly.

    Exactly ^^.

    Y did it break tho?, was it because the engine got too hot and tension snapped the weakened metal?.

    Probably just a defective part. The reason for break in is to set the rings. If clutch parts are breaking they were possibly bad from the factory.
