Just bought a 2002 Coguar, and the speedo dosen´t quite work, I´ve heard they are prone two breaking ever 8 months or so, but why? Is there one particular thing I could replace in my speedo to fix it and prevent it from breaking again, or is it just going to stop working again even if I replace the whole lot? Also, if it is just the coguar speedos which keep breaking, can I just replace it with one from another make/model of bike, and how difficult could this be to do? Any help would be greatly appreciated, Ed. M
