Using the GPS to calibrate the speedometer is the greatest thing I have learned here on V-Twin forums.

wkohn is correct though, the lower the frequency number, the lower the speedo will display.
For my bike, stock wheels, Michelin Commanders MU85, stock final drive pulleys, and a Baker DD6 I came up with 1153HZ.
