Speedo error

I fitted my GPS to the Gpz today and went for blast. As it has a mph
function I checked it against the speedo and seemed to be 8-10% out when
doing 40mph the GPS read 36mph and doing 70 the GPS read 65mph. So that
means when I did an indicated 140mph at the weekend, I was actually only
doing about 128mph.

I know most motorcycle speedos are pretty inaccurate but how does this
compare with anyone elses.
