That is a hot spot from a harsh engagement. The flywheel had less 500 miles on it. No need to resurface this over a hot spot. It's a discoloration due to heat. I can guarantee its not warped over something so small.
My $2400 triple disc on my evo had worse markings on it in 100 miles. 20k miles later still spec*d out against runout & parallelism .
