Inacurate Speedomoter/anyone got a fix it idea?

[HOHO]

 It's my 2nd year now and I've gotten all the bells and whistles I wanted to customize it to my satisfaction and I'm really enjoying the bike.  Now on to more practical matters.  Kymco says there's an agreement between companies to put the speedomoter 10-20K an hour faster than is the reality.  I don't need someone else to help me control my speed. I'm 56 and had 1 ticket in 40 years.  I went out with the Mrs. in her car and with the aid of signals figured out that starting around 80kph(Canada-kilometers) I'm faster about 10K.  Up to 120 KPH it seems to be about 10kph different.  Now I know we drive fast in Quebec but sometimes I have to hit 140kph just to keep up with the faster traffic. I figure they must be doing about 70 miles per hour (120kph) give or take a few.  Has anyone out there figured out a way to fix this problem?  Please let me know.
Thanks

Put a cheap gps on the dash. I went from an xc 250 with a gauge cluster in kmh to a xc500 in mph both are off 4-6 mph per my gps.

The numbers for kilometers are much larger than the mile numbers on my 2007, and they are on the outside edge of the speedo. So I have learned that on my bike at 100K I am doing exactly 55 MPH. At about 120K I am doing about 70 or so MPH. I just live with it! As long as I know what speed I am really doing I don't care, as there is nothing I can do about it anyway. I have a GPS, but I don't want to have to un-plug and remove it each and everytime a get off the bike. I hope future bikes have better speedo's.
