Recently my speed odometer has been dropping out at the start of the ride. Sometimes it will regestor for a min or two then drop. After about 6 - 10 miles it comes back to life. Because the cruse control is tied into the speedo it doesn't work when the speedo drops out. This could prove to be a real problem on longer rides on slabs. (have 109,500 miles on the 2003, so many long trips happen on this bike) Any idea as to the cause or solution?
