So I'm new, and you guys are helping me learn something everyday. What would you say are the top 10 (or 5 or 20.....) things to do to a "factory" ATV to boost performance. I have a simple '04 Rancher manual 4X4. Do I really need to mod the bike; I'm a trailrider and not a racer. I'd rather cross a creek than jump a ramp....
