I'm going to do a top end job on my '01 YZ250 but I'm a rookie on the plated bore thing. I don't have a problem with the top end. I want to change it before I do since I have no idea how many hours the PO has on it. I'm going to use an OEM piston. So, am I safe to just buy a "D" piston, which is the largest OEM size for the YZ? I was going to take it to a shop to do the hone (deglaze) and have them measure things and since the size differences in the OEM pistons are so small, the shop gave me the impression that if I brought them a "D" piston, they would hone to give the proper clearance since the plating on the bore IS thick enough to do this. Is this the proper way to do this or is it not textbook but workable? Thanks.
