iv got a 03 yz450f that recently broke a valve and had done a fair amount of damaged. im pretty ure that my head and cylinder is ruined, along with all my vales and piston. what im not sure about is why this happened. i know that my valve clearance was within tolerance and i know that my timing tensioner was still working. do any of you have any ideas about what could have happened? could it have jumped time or did i just break a valve?

any input would be greatly appreciated. i have some photos of my head and piston on imagestation. account: rbm33 password: 123456
