It wasnt the PowerValve either. I never removed it.

I didnt really think of it at the time (last night), but I remembered (this afternoon) that as I was removing the forward base nuts, they seemed to come off way too easy.

I think I had an air leak in the front base gasket and that is what burned up the front of my piston. I just didnt have the nuts torqued properly.

Now Im gonna upgrade to a 300 jug from GoFasters and chalk it up to an expensive lesson learned. My origional jug is a complete loss. It has a big crack that runs horizontaly between the exhaust port and the PV barrol bore.
