Just a thought... You're bike hasn't had a Speedo-Healer fitted at some time in the past by a previous owner? If it has, it could be that it's calibrated wrongly?

Has your bike got any fuelling devises fitted? Power Commander, O2 optimiser etc. Or maybe a gear position indicator that takes a reading from the speed sensor? They can all occasionally cause random speedo errors, particularly if not fitted correctly or the connectors get damp/corroded.
