Yeah mine started it today. Riding along at about 40 mph and the speedo showed 90 mph. Later it stuck on 60 mph and would not move off of 60 even when the bike was shut down. Going to the shop tomorrow.
mine is doing the same thing (stuck at 120 right now) it stopped at 60 and then added to it. I took it to the dealer of Saturday, they looked at all the connections and unplugged the pickup, plugged it back in and the speedo reset, okay. I rode about 10 miles and back to 60 it went. Called back to the dealer and let them know, they are working on plan B.
Tjohn - the t-bird speedometer is not cable driven of the front wheel like the america, they are digital and pick up off the transmission. different animal.
