just looking around for some big bore kits for a 94 yz 250. found a couple but i dont know if they are trusted companys

Big Bore Kit Master Price List from Forward Motion



YZ 285 Big Bore | YZ250 | Yamaha | Motorcycle Kits




i dont know if you can just bore the cylinder out to that much or you have to get a new cylinder if its just boring KOR all the way but if not i dont know any other companys that sell them and are trusted

The best thing to do is a little hunting on a YZ forum.
