scored cylinder and piston xr6r

I'am in the process of replaceing the countershaft on my 86 xr6r. There was oil on top of the piston, no good. There is scoring about 1 inch wide on the cylinder and the piston below the rings which leads me to believe a chunch of something came from below. anyways i think i can have the cylinder honed but my question is, should or can anything be done w/ the piston? The piston is new and i really do not want to bore it, I'am already resleeved and at 100mm. the scratches don't look to bad but are visible. I will get the cases split yet and see what is going on in there in a few days. Thanks for any help.
