With it being a single speed your definetly better off staying with it, especially if your looking for low end climbing power. Just get you a 13t clutch bell and a 49t spur gear and the sh18 with tubed manifold and tuned pipe and you'll be set. When you get everything set up, post some vids one here. I haven't seen any shockwaves that are upgraded. It'll be cool to see one shredding some dirt.....lol.........
