    My crankshaft just broke at the rod journal, can you believe that crap. It only has about a quart ran through it, ran strong too, right up to its breaking point. Has this happened to anybody else. Its a Hyper 21 8 port. This was for whinning purposes.

    Ive never heard of that happening to anyone. Usually the con rod will blow before anything else. Call ofna, theyll probably send you a replacement.

    I figured that it probably would only happen to me.

    Did you modify the crank at all? I've seen it happen a couple of times, but only to modified cranks. Sometimes people take too much off the sides in hopes of lightening up the crank a little, and that weakens the crank in the very spot you are talking about. Good luck.

    No mods. I finally got ahold of Ofna they said to send it to them. I'll let you know how they take care of it. Thanks.

    Well, got my engine back today and they fixed it and didn't charge me anything.
