Speedometer not reading correctly
06' FXSTB-I Night Train
Here's the issue. I turn the bike on without starting it by the gas tank switch and the speedometer jumps to 10Mph. If I turn the switch to accessories, it resets back to zero, but jumps to 10Mph when I switch it to the start position again (sometimes it stays at zero until start it and move).
After I start it, put it into gear and move the speedometer climbs very quickly up to the 50 Mph range and drops to 45 Mph and stays there when I stop. When I drive it down the highway, it pegs the speedometer and then drops to around 50-55 Mph when I come to a complete stop. If I turn the bike off and turn the gas tank switch to accessories, it reset the speedometer to zero, but back to 10Mph (without moving and in neutral) when I turn it to the run position again.
Any ideas before I go waste $70 on a speed sensor?

I'll check for loose connections, clean the speed sensor and get back to let you know if it solved the issue. I'm leaning on poor continuity seeing its a problem that shows symptoms occurring before bike is even fired up.

Didn't work.
Checked and Cleaned Speed senor connection, battery connections, ignition/accessories switch and speedometer connector. Problem still exists.

this is a link to a video of what the speedometer is doing when I turn it on.
It doesn't show in the video, but once in a while the needle will spin up and sit at the odometer and stay there. When this happens I can switch it to accessories and it'll drop back to 0'ish.

I haven't noticed this, but think mileage is considerably off. My estimate by maps is under 400 miles, yet it's showing over 500.

Speed sensor could be bad , you could try unhooking your battery for 10min to reboot your ECM as it sends the signal to your speedo.
See what happens if you leave the speed sensor unplugged.
