3.4 means Right hand #3 or #4 bowl for multi cyl bike carb bank. as you sit on seat 2 RH bowls are identical. 2 LH ident but drain screw was opposite. 450 500 550 650 700 bowls are all about same size and made in 80 81 82 83 84. polished means it is one of outer bowls to look kewl. Honda = interchangeability. back then Hondoie made about 80-100 different models per year. atc street offroad etc.
