    ok I talked to a company based out of Ca. who actually made this cylinder that I own about ten years ago and they guy told me the wiseco still makes a piston for this machine but that pro-x discontinued them.. Wiseco makes them in the pro lite for an 85 atc250r but when you look them up for an 85 cr250r they don't show it. thanks anyways but hopfully this will help someone out in the future that might be running an old 265PV cylinder

    I went through this about a year ago looking for a fresh slug for my Sparks 265 pv, went as far as contacting pro-x themselves. You are correct, that piston is no longer available, I ended up buying the Wiseco as well for mine.
