Most Jap bikes of this era have the same speedo ratios.
As long as the wheel diameter is the same, almost any speedo should work ok.
Same with tachs - I've personally interchanged both on many different Honda models of the 70's, and they worked fine.
Right now I have 360's on a 450, and I've used them from 500 4's, 350's, etc.
