Message: [QUOTE="76GMC1500, post: 1237403, member: 73139"] There is a burn pattern on the crown on my old piston. I couldn't tell you exactly what I did to get it. I Scotchbrited most of the old carbon off and ran the bike for a short time before I decided the piston was trashed and replaced it. I haven't pulled the head on the new piston yet so I couldn't tell you how that one looks. I've never had any carbon whatsoever on the underside of the head, you probably shouldn't either.
