that is the worst DR kit seizure i he ever saw, mine lasted about 2400 miles or about 60~80 hours of use and i soft sized it a few times due to lean jetting and looks new compared to this. based on the pictures the piston is shot, the cylinder is probably warped,no longer circular and needs to be re bored in order for a new piston to fit properly. honing is only good if the cylinder is still true and square and is only made to brake the glaze so oil can stick to the walls. conclusive i think yore kit is shot and you should purchase a new one unless you know some one who can bore cylinders for free. a bore job cost about 80$ and a over bore piston is about 60 from treats, at that rate you might as well buy a whole new kit.
