Definitely running lean on the edges. Also there appears to be a lot of detonation damage around the perimeter of the cylinder. I see lots of pock marks on the outer edge of the cylinder (top of cylinder, right side of picture)

Check your timing and AFRs.

It is even more interesting that the lean section is on the top rear of the cylinder where the spark plug is located. Loose head studs may be the cause.
