    Rpm question?

    Hello . On a gs1100 gl shaft. What should the rpms be at 60 mph??

    Doesn't that depend on the gear you are in? My GS1000G seems to like it best over 3000, but like a little over two thousand is fine to make it not do that thing it does in too low rpm.

      In 5th at 60 it's over 3200 rpms

        The 850 at 60mph is a bit over 4000 rpm on a forty year old magnetic coupled instrument, if that helps.

          Years past always kind'f normal for 750's & up; 1000 rpm.= 15 mph. , not exact but good rule of thumb. By that reasoning, 60 mph. =4000 rpm.

            According to the chart that I have, it should be turning 4186 RPM at 70 mph.

            Slow it down to 60, it should be turning 3588 RPM.

            The gearing is different for just about every size engine. They are geared so they are spinning fast enough to make the power necessary to handle the speed. As an example, my 850 used to turn about 5000 RPM at 70 mph. I have changed the rear wheel, so it's now closer to 5400. My son's former 650L is closer to 6000 RPM at 70 mph.

                I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

                  My chain drive 1100 EZ ran about 41-4200 at 70, 35-3600 at 60.

                    Cycle World said 3811 at 60, though mine always turned at closer to 4K. (Stock gearing).

                      Extract from 1920s flying manual

                      If one morning you don't have the full 1750 rpm against the chocks, the inexperienced pilot sends for the mechanic to fix the motor. The experienced pilot sends for the armourer to change the tacho........
