Yes it would if it needed one, especially if i was doing it! Any play is too much as far as im concered.I did say that the pin would need drilling for 450/500 bolt.I dont like needle rollers in that situation as the angle movement is not a lot so needles dont actualy roll, same with taper roller headstock bearings, they indent just as bad as the balls but are easier to assemble
My CB1300 has 2 ball bearings on the O/S but a long needle roller on the N/S, possibly because it will withstand the pull of the drive chain better.. Oddly enough it's not the bearing that starts to fail but the tophat bush that runs inside the needle roller. Due to lack of assembly grease no doubt, mine got an advisory on it's first MOT for swinging arm play.
