Recently I have added a new tail light and new intergrated signal frame sliders to my 1999 hayabusa. Well upon getting my bike back form the shop I noticed that my speedometer did not work. My tach and other gauges work fine and when I turn the switch on all of my gauges raise and go back into position to prepare for start up. My bike has a speedo healer, as well as a power commander . Could it be that my speedo healer box has gone out , or maybe a sensor of some sort? Needless to say, I will not be taking my bike back to that shop due to me having to replace my main fuse as well as this new issue. They really did some sloppy work with my wiring and the service was very bad. How can I fix this issue and will it be a costly fix? I love to take care of my toys and this issue has me mad as hell when I ride. If anyone has any feedback please advise thanks a lot
