Well, I installed the speedohealer. I had to remove all of the pins and bolts that hold the fairing on but I just pulled the fairing back to access the speed sensor plug. I did not have to remove the fairing. I went out before calibrating with my GPS and did different speeds and determined that my speedo was 7.5% too fast, which is pretty good for a busa. My gen 1 busas were 9% too fast. I then set the speedohealer to the correct percentage and did another test and my speedometer matched the GPS. The new speedohealer is much easier to program than the earlier model. Pretty Cool!
