wow wast of my life reading this thread. the dude with the white truck in his sig with the mud tires and like 2 peace rims. has 2 or 3 zillas i cant remember. he said 2 me the zilla is restricted bye its 5 speed. his banshee beats it every time. his mods were bolt on's on the shee and bolt on's on the zilla.... there fast but they had so many issues. the bearing and what not the head gaskets blew so they had 2 make a 6 bolt head and cyl... there heavy as a boat. but i belive with a diffrent tranns it will have it. idk about fully worked zillas vs fully worked banshees. because all the factors come 2 play. so in my opinion id stick with the shee... its a better all around bike and faster... yah i said it.....
