Long story short, I didnt change the damn cam chain tensioner when it started goin til like two months later. She got to the point where she sounded horrific, so i stopped riding and got a new tensioner, put it on, but she still sounds like this: http://www.sharenow.com/base/content/54121/ (I start her up at second 18 of this video)

I changed the oil filter, oil and fuel filter about a week before the engine started sounding like this as well.

She's now been sitting for about two months, I've not tried to start her since.

Anyone have any ideas?

Thanks

 

sounds like metal on metal, definatly not good. drain the oil and see whats in it. if theres metal, check color and if its magnetic or not.
hard to tell in the clip, is all the noise is in the head? the valve cover isn't too hard to remove. pop it off and see whats inside.
