I have a 97 Road King and adding a fairing with aftermarket digital gauges was wondering if any one knows how may teeth are on the flywheel so i can get the tach to read correct!

 

Hi from the UK and welcome to HDF. Got family in Minnesota! I thought the speedo is driven off the trans on your model? Call over to the Evo section, someone over there should be able to answer your question. They are too busy jawing to call in here!

 

With aftermarket gauges you may need to add a speedometer corrector. Use a GPS as a guide and adjust the speedometer to match.
