wondering if anyone else has seen this. Perhaps since I dont generally turn on the nav lights on our '06 Sportster 155 I hadn't noticed this before. Turning on the nav light switch makes the tach go nutz, sometimes going back to zero, sometimes pinning the other way, though the engine is running fine..???
Wacky Tach
