Speedo

[sturmannderss]

I just bought a 2005 with 4.700 miles. I was riding it for about the 5th time today when I noticed the speedo was not working. I went about another 5 miles and it was reading 10 mph. Problem was I was on I-485 probably doing 70. Within another 10 miles it was working fine. Are there any known problems with the speedo on these models?? I did notice that the odometer continued to regidter seemingly correctly the whole time. Where does the speedo pick up the info from? I didn't notice a wire to the front hub as most mechanical speedos fed from. Thanks for your time.
