im not to fond of the axe rossis, ive seen to many of them break and not run good, so i try to stay away from them. Im currently running a Highly modified Novarossi T21BF and im getting walked away from by a S821B, 21-5, and a Sirio Kanai. this motor currently passes Vspecs, WS7s, and other engines of that caliber. im looking for something insane here. bottom is is something id like but dont need near as much as i do mid and top end. the back stretch on this track soaks up top end.
