I was riding down the interstate, everything going great when my F1 light came on. Shortly afterwards, I lost my speedometer indication. It went down to 0 for about 10 seconds then returned gradually to normal. My alternator output remained normal as did the running of the bike. When I got home, I turned the bike off and was going to pursue the issue the next day. After starting the bike again, the light was gone. Any input would be greatly appreciated.
