error codes on rev counter

[elektrikAlien]

Hi - when out on my 2002 fzs1000 today, the rev counter started behaving  strangely -it was jumping between 0 - 1000 rpm and the temperature light situated on the dial flashed. This happened a few times and then the rev counter behaved normally.  I did not notice any problems  with the  way the bike was running.  I looked up the error codes, but couldn't find one  for 0-1000rpm. Does anyone out there know WTF is going on ??
Thanks guys. :rollin
