May be of some use: (gs 650)

In 5th gear as follows:
30=2500RPM
50=4000RPM
60=4600RPM
70=6000RPM

5K about 60mph 6K about 80mph

A good rule of thumb for 750's & up, from that era. 1000rpm = appx 15mph. 2000 = 30, 3000 = 45, 4000 = 60, etc. It will be very close.

Yup, rather close. Don't know if the G and GL models are geared any different, but my (wife's) '82 GL does 14mph/1000rpm.
That is according to GPS, which is conveniently close to what the speedo reads, too. \\/

Therefore:
3000 rpm = 42 mph
4000 rpm = 56 mph
5000 rpm = 70 mph
