Default Speedometer shows approximately 9.5 miles too little

Hi everyone

I have a problem with my speedometer, I recently changed my old miles speedometer out for kilometers speedometer, since I live in Denmark, now the problem is, that my current speedometer shows approximately 15 km too little per hour, or the equivalent to about 9.5 miles too little.

What can I do to solve this problem, are there some "gear" gizmo exchange ratio you can put between to increase the speed?

Kind regards Jesper

Need to change the gears, hopefully just the driven gear, that is easy or possibly the drive gear, tougher task. Might take a little trial and error but the gears are cheap and readily available.
