i've got a stock 04 F7 ext (non DD). on the last day of our ride in the mountains, the speedo went completely whacky. the needle was bouncing all over the place and it was switching from analog to digital. it was also switching from mph to km/hr, even the lettering for the fuel level showed up a few times, and when i'd shut it off the needle would stay at like 70 mph, or wherever it wanted to. it did this the whole day long, as soon as i would start it up until i'd shut it off. i started it up a couple times since then and it seems to be reading just fine. I dunno anyone have this kind of trouble before? the only thing that i've done to this sled is put in a polaris 12volt dc kit for my gps.
