I just bought a 2004 Road King Classic and the bike is in good shape overall. It starts fine, however, after running about 30 minutes, the speedometer stops, and unless I stay on the throttle, it wants to stall. I found a blown fuse the first time this happened and replaced it. Then it happened again and I replaced another. This last time, no fuse blew, but after the bike sat for the 5 minutes it took for me to check the fuses, it started up and was fine. Anyone have any thoughts?
