Hey guys, I was riding to work the other night when all of a sudden my speedo went flat and just read 0. The revs move etc but its not registering any speed at all. I have had the sprocket cover off and cleaned and had a look at the sensor but everything seems fine. I didn't notice anything noise wise when riding or anything but now I'm confused as to what it could be. Has anyone got a photo of what their sprocket looks like so I can compare incase something's missing or anybody had the same experience? Cheers people.
