    It can't really be wrong unless your clutch is slipping. I don't have a 650 anymore but it should be something around eighty kph?? It's a high RPM engine, and it's geared accordingly.

      Friends with any local police??? Have one of them use the radar gun to see if they get the same as what your speedometer says.
      MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)
      1978 GS 1000 E, 1979 GS 1000 S, 1973 Yamaha TX 750, 1977 Kawasaki KZ 650B1, 1975 Honda GL1000 Goldwing, 1983 CB 650SC Nighthawk, 1972 Honda CB 350K4, 74 Honda CB550

      NEVER SNEAK UP ON A SLEEPING DOG..NOT EVEN YOUR OWN.


      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.

        It's about 12 mph per 1000 RPM, so 48-50 mph (80 kph, as tkent suggested) would be pretty close.

        Also as suggested, no need to change it, that's where it works quite well.

          Thank you for all answers. I just finsh ride. Result is on 5th gear at 4000rpm 52mph (85kph) and at 5000 rpm 71 mph (115 kph). I gues all is fine.

          Last question is "TOP speed" but this I wish try later due to my lack of experience.

            4K at 52mph does not reasonably correlate into 5K at 71. 5K should only be around 64mph.

              What you think is wrong?

                Bad speedo like mine which stopped working last year, but repaired itself somewhat over winter. Erratic- reads 5mph low at actual 45 mph. As to top speed stuff, let me know when you hit 9500 rpm in fifth! Get a GPS to know for sure.

                    Simple mathematics will tell you that if you are going 52 mph at 4000 RPM (13 MPH per 1000 RPM), you should be doing 65 mph at 5000 RPM, not 71.

                    A difference of one or two MPH could be written off as viewing error or needle bounce, but SIX MPH is too great an error.

                      I use GPS today. It's speed meter which is not alright. RPM are also depend on road level...
