    How fast is is your old GS?

    Those that have 85 MPH speedo's use your tach to determine your speed when you are above 85 mph. When you tach out in high take notice of the tach reading. If you are at 8500 rpm then 'half' that is ALSO half the speed. If 8500 rpm then bring down rpm to 4250 and read your speed off of the...
