Hey guys just getting ready to rebuild my '03 yz450f. New parts that I am installing are a new Hotrods crank and rod along with a CP mid compression piston. The head, valves and cam are going to stay stock for this year. I have one concern about the cylinder, it has a bit of an edge worn at the top and bottom of the stroke. I have honed it but can still feel the lip at each end. Should I be concerned??? does it need to be re-plated? There is no flaking or other problems in the bore that I can see. I do not know the hours on the bike as I bought used in Dec. It will be used for trail riding and some mx track but I am by no means gonna be pushing the bike all out. Thanks.
