That's definitely odd. I check my speedo against my aviation GPS every year or so and have found that the electronic speedo on the CB11 has always been within 2 mph of the GPS speed. Same can't be said for the old mechanical unit on the CB750. It's within 4 mph at highway speeds and the error increases as speed increases.
Since your problem seems to cropped up recently, I'd suggest inspecting both the ring and the sensor. Since the sprocket change involved working in the vicinity of the ring/sensor something may be loose or out of place.
A tried and true diagnostic technique is to go back and check the last thing you worked on, even though seemingly unrelated.
