Strange sound...

[MotoXdevil7472]

A couple weeks ago i was riding at a local track and going off some jumps. when i went off one of the jumps i landed, and i heard this rattling sound coming from the engine. does anyone have any idea what this sound is? i was thinking maybe it was the timing chain but i dont understand why the sound started right when i landed off a jump.

does it still do it? where is it coming from? also, the reason it started when you landed is most likely that it was weak and when you landed it just came loose or broke, whatever it is...might not seem like it but everytime you land stuff in the engine wants to keep going down...all simply physics...anyway idk what it is but give some mroe details and im sure someone can help you

yes it still makes the sound. it seems like its coming from the top end. but i cant tell for sure.
