Speedometer out of whack

[Coseverde]

My speedometer is rather inaccurate (10km/h over), and my odometer is as well (2.7% high).  Any idea how to improve the accuracy?

At what speed was your speedometer 10 km/h off?  GS speedometer reads about  8-10% high.  Also changes from new tire to worn one.

Speedometer error is cut about in half with a 110/80 front tire in place of 110/70 oem one.  Should put odometer closer to correct.

Probably 50+.  I have OEM recommended sized tire on the front.
