That's a 3% speedo error. I'm distracted and low on caffeine, but I THINK that means your speedo reads high... Easy enough to verify since you have a GPS. Just crank her up to 60 or so (higher speeds are better) and compare the GPS to the on board speedo.
The stock speedo on my 800 is pretty accurate up to 45 or so and not off by that much at higher speeds (like 5mph at 80, which is more than 3% error).
