Speedometer truth

Hello all just got my Busa , haven't been riding it a real lot as of yet. But have noticed the speedo sure does seem to be reading slow. My other bikes seem to read a little slow too but this ones seems to me to be at LEAST 15 OFF. Will check it out with my gps soon, but it is raining here now and wondered if anyone else tried it.
 
Most speedos read high if not calibrated with a Yellow Box or SpeedoHealer.
 
10% high sounds about right, still running in here, but 161 in a blip and GPS said 146 for a Gen II
 
Yup... 10%, but it's not linear... the faster you go the less accurate it seems to be.
Yellow box or speedohealer works just fine. Don't forget your GPS can be off (around 2%)
 
Got a SH here, just make sure the wires are mounted to where they don't collect water!!! :whistle: Mine was about 7% off have it set at -7.1%.
