I did change tires from the MX only to a pair of Tusk dual sport tires and love them. I have the part number but can find no one who can order it.

Rebel gears makes custom sprockets. Just have your OEM sprocket dimensions, or send it to them, and they will make one with the desired tooth count.
4 tooth isn't going to make a noticeable difference quite often
I myself would swap a 51t with something like a 35 if it would fit.
Check the bolt diameter, and swingarm clearance. Then go as small as you can go.

For a 250 to do 60mph it needs to rev below 6k rpm in 4th or 5th (second last gear). That way you'll have top speed in this gear, and 15mph lower than peak speed in final gear (good for suburbs, and good in fuel economy).
