hey i used to have a 400ex i know how it is to switch to 2 stroke. i know this a banshee will bite u if u dont know what ur doing. i know from experience.anyway tell u what do u go to tracks im sure a guy will let u ride there banshee. i like two stroke better than 4 by far. another good thing about banshees is yeah u got to get two of everything but, its like a universal quad u can get ANYTHING u can dream of for them. i mean anything. but u will love a banshee. ive never heard anyone talk bad about them cause there the badest quad out.
