I noticed that on mine too. I gently pick at it to manually remove any flakes that might otherwise wind up in the tank. But there is the filter on the petcock to catch such debris. And you may have the hidden filter still in place. I pulled the hidden filter and installed an inline filter. I'm not too worried about the peeling... it's not excessive on my bike anyway. But it's there and it does tend to raise an eyebrow.
