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.
