19/40 is the tallest gearing you can get for the Trophy. I don't think a 20 tooth sprocket will fit in the housing, and I haven't found anything smaller than 40 that will fit the rear. For the 1200, this is probably the best overall gearing unless you're an acceleration freak. This may be a little to tall for the 900 unless you ride solo and lightly loaded. Maybe 18/40 or 19/43 would probably be as tall as I would go with the 900.
Travis, don't know who trashed your carbs, but you should be getting much better mpg's than that. Is this a 900 or 1200? If no other mods have been done, I would return to stock jetting. 2-up, loaded heavy and pushing hard I get 36mpg out of my 1200.
