    Speedometer Question

    hey everyone I have an 83 Suzuki GS 750 and my speedometer only shows up to 85. I've seen on videos that some people have where the speedometer shows 140. I want to do the same for my bike what do I need to do. And is it an easy install?

    i think all you need to get is a speedo, drive gear and cable should be the same. but lets have someone with more knowledge confirm this

      You need a '79 or earlier guage. The speedometers built after '80 only went to 85.

          Remember that a guage calibrated for 85 mph won't sweep correctly with a 140 face. The only way for it to be accurate is to swap the whole guage.

            The drive unit should be the same. I swapped my 82 85mph speedo with an 83 140mph and it works fine.

                Swapping faces will not work. As meantioned, the internal gearing wiill not mesh with the numbers on a 140 face.

                Whats needed is a full 140 speedo swap. Gear drive at the wheel should be the same whether its pushing an 85 or 140 speedo.

                  The 85mph speedo was U.S. mandated. Find one for your bike from another country. It may be in K.P.H. but will have a full sweep.
                  Or just get a gps.
