Check and make sure that nothing else is "inoperative." Specifically, do all the warning lights on dash (neutral, FI, brights) work? Is your tail running light/brake light/turn signals all functioning? The reason I ask, believe it or not, is that on my 03 1800 R, the power to the speedometer runs on same line as taillight. I had a wire abraded under rear fender, shorted fuse in right hand sidecover, and took out the speedometer, neutral light, and I think it was the red engine light on startup.
If your only problem is the speedometer, I'd recommend just checking fuses and if you find one blown, try to run the short down. I have no experience/knowledge of the speedohealer though. Hope this helps.
