Found out what caused the seizure on my 03 yz250f. (check pic below) Instead of replacing the valves, I was thinking of buying a used whole cylinder head in good condition for a very good price. It comes with everything including the valves. Or should I just replace that one broken valve?
Here is my list of parts I think I should replace. Is there anything else that I am missing? Would appreciate your input!
