Athena Big Bore Kit

Well mostly good. "I bought the kit for my 2001 yz125 . The new head for the cylinder had a little dent in it. Either form manufacturing or shipping. I didn’t use it because I didn’t want to risk it being faulty. Hard to see in a picture, but straight edge won’t sit flat across."
