This is the story, i put this White Brothers rev box on my 400ex and my friends like "i should test it out" so he hops on it and this thing is cold, it hasn't been ran for hours, and he just revs the crap out of it and it dies. And now i started it and when its running you hear this klank-klank noise coming from the engine. I don't dare start it again that would just make problems worse. Whats wrong with it??????????????
