You will need to trim the belt gaurds to allow clearance for the tire. I think you may need to trim the top part of the inner mud flap even if you are not lowered. But if you are going with that tire, I would lower your bike also. I personally think it has a better stance lowered with the 230. If you leave it at stock height you will be about an inch taller since the tire diameter is larger. So if you lower 1 inch, you will be back at stock height.
I personally would do the full trim just to be on the safe side. Real easy to do and you will have your tire off anyways. The mud flap is only held on with 4 screws. And who knows, you may want to lower your bike one day and you wont have to take your tire off to do the trim.
