Hi the time has come to pull the jug off my 2003 KDX220 and replace this piston its done 2400 miles and I don't know if the piston is stock or not.
Just wanted to ask what you guy thought about bore do you think its safe to put in a new piston (Wiesco) or do you advise scotch brighting the bore to give better oil cover.
Any other help would be great.

Assuming the bore is within spec, then yes going at it with a scotchbrite pad is a good idea. It's more to help the rings seat.
