    Not sure of the biggest bore you can go. To go really big usually you have to install a thicker sleeve. They get hot when the wall gets too thin. Example my 400 is bored to 426 if I want to go bigger I have to change press the sleeve out bore the jug and press in a thicker sleeve. Personally i also would not do it. I would bore to the next size up, opt for the higher compression. put a cam in while your at it. Full exhaust made a difference on mine. I got the SuperTrapp its not that loud. I hunt with mine so. HMF are way louder, even with the quiet core in its louder than mine.

    I also have to agree take mud and the ability to carry and ice chest and other equipment out of the equation. For pure cutting up a sport quad is nice to have. I own both and there are times when I'm on one and wish i was on the other.
