Try a 38 or 40 tooth sprocket. You lose some acceleration ( on a 250r it shouldn't matter), but you gain alot a of top end.

49 tooth, thats a huge sprocket, I think you mean a 39, I have 14/39 on mine and it hauls, but I have a full port job, cut head, a/s carb and more. I'm using a 182 jet, now its a 330, I haven't figured out jetting yet.
