Did you change the tires from stock?
I found going from a 50 profile ratio to a 60 caused a 10% difference in my speedo compared to gps.
I switched to 17" rims and installed a speed-o-healer to correct the speedometer.
They report that speedometers can be off as much as 15% from the factory but I have never heard from a cb owner of anything that far off without modifying something.
Keep in mind your mileage will be off too.
