upon1stuntr6

im currently building a 2006 yamaha r6 (50th) and im looking to get a new fuel tank. i was wondering if there were any tanks other than stock i can use. id like to get rid of the tank fairing and use a full tank. its a stunt bike so the tank will be dented. and im willing to do mods to air filter or tank itself to make another work. does anyone know if theres options or am i just stuck with a stock tank?

thanks mike
