i agree on him with everthing but the 2into 1 carbs. because the two into one carb setup gives it a moreharsh powerband and will wear you out faster. but almost everyone you talk to will tell you that the best mx pipes for a banshee is the paul tuners mids and the 250r geometry in the way to go. but motor wise, the banshee has alot of power but the thing is to get it smoother and more useble power. you want to work on your suspension befor anything, and there are so many good shocks and a arms out there its hard to go wrong with any of them. just look around and if you need any help just ask thepeople ion this site there very good with this stuff.
