So I went riding with this new setup for the first time today, and I'm not crazy about it. It's really bumpy in the woods, it doesn't climb hills as well as it used to, it's hard to carry a wheelie now, and it not as fast in a straight line. I think the straight line lacking is due to the gearing change with the smaller tires. I can definately see where it would be much better for MX, it handles much nicer. I have a new rear sprocket on the way. I'm actually debating on putting it back the way it was for now. Once my 500 is done I have another 250 I'll be putting together. Then I could have the MX one and the trail rider.
