Could be the turn signal module itself but it could be the speedometer also. there is a white/green wire from the speedometer going to the turn signal module, block the bike up and run in gear, turn on the blinker and check for a signal on that wire. there is a reed switch in the speedometer that will send the signal for the turn off. this is a sealed instrument so you will have to buy another one.

Do you have a full-blown Partner Messaging or Mail module? If so - the hard drive may have issues. I would shut the system down and restart it - as it starts try to listen for hard drive noises by the Messaging module. If the module has a red or orange light - the drive masy need replacement
The older Harley speedos are driven by a cable and can easily be replaced by any type of cable driven speedo. I assume your Sporster has the tank mounted dash (my 72 is this way), it's fairly simple too unbolt the dash and remove the speedo. If you're wanting to replace yours with a newer (electronic pick-up) that could be quite a project. Hope this helps
On the new bikes, the speed and signal are in one circuit, and on some the horn is in there too. This is most likely going to be the fuse or relay for this circuit. I don't know their exact location, but your local dealership should be able to tell you. If the fuse and relay are good, then you're going to have a short in the wiring, probably a bare wire or a loose/broken ground. Rare, but occasionally, a switch on the controls will hang up and cause this also. Start with the fuse and relay, then go to the wiring and switches, and let me know.
This is going to be one of three things, and you should check them in this order, 1- you have a loose connection, bad/broken ground wire, or an exposed/bare wire on, around, or in line with the rear signal that is staying on. It's common for the wiring insulation to rub through and short at the bend where the signal wires go through the signal mount and run down the rear fender strut. 2- the switch on the bars is sticking or malfunctioning, however, this is less likely because it usually causes both signals to remain on. and 3- the flasher relay has malfunctioned and needs replaced. I'll bet that this is a bare wire, so start by tracing the signal wires for the right side. If you don't find a bad wire, then replace the relay. Let me know what you found out.
If you have the electric speedo, then it's one problem. There is a relay that all three of these go through in order to work. I'll bet you popped the relay. I don't know exactly where the relay is, but your local dealer can give you the location. If you have the manual speedo, the it's two probs. First, the cable to the speedo gear on the front hub has most likely pulled out a bit, and second, the same relay as before, only the speedo isn't routed through it.
Most of the time when this happens, it's in the signal switch on the bars. Usually they just get a little corroded and stick, so cleaning it and using a little WD-40 will take care of the problem. Occasionally the switch fails, and needs replaced. Take the controls apart and clean the switch, and I recommend to do both switches while you're at it. Try this and let me know.
ok the twin cams have the brain located right under the seat. think about it, brain **** proximity issues here bro but not to worry it's harley who had their head too close to their **** anyhoo check the connections at the wiring harness to the module for corrosion or otherwise nefarious condition and I bet you get it licked
