It's a mechanical gear that's attached to your wheel and transmits by a spinning cable to the speedometer. I'm thinking "not". Especially since below about 7K and above about 9K many tachs are indicating normal. It has somehting to do with heat, resonance, and the cdi/tach.
If it was as easy as a speedometer cable or gear, Kawi wouldn't START with the CDI, move to the tach, and then go CDI again and again and again. Remember, once you report the problem, Kawi goes straight for the CDI, doesn't even ASK about other indications. That says they KNOW FOR SURE there's something wrong in the CDI/tach loop.
Other than the known 10% error on many bikes, there doesn't seem to be any issues with the speedometer.
