ya seriously, u gotta consider just the top end alone. cam,rockers,springs,timing chain and gears, rods n all the toprque specs have 2 be EXACT . . . a banshee is a much simpler and more dependable machine than a raptor. but if its a thumper ur after ride a new yamaha 450 b4 u buy a raptor. i heard nothing but god things about em. all else y not sell ur banshee and get a newer or brand new one! good luck decision making!
