Speedometer reading 3 mph over. Any way to calibrate?

[ZoneIII]

I seem to remember reading here or somewhere else that it's common for R3 speedometers readings to be off. I've suspected that mine was reading about 3 mph over since I bought the bike and I was able to confirm that it is doing that recently. It's no big problem and I can live with it but if there's a way to re-calibrate the speedometer, it's something I would probably do.

Any suggestions would be appreciated. I do have TuneECU although I've never used it and I also have DealerTool which I have used to balance the throttle bodies and bleed the ABS system.

TuneECU will let you change the speedo, but will also throw off the odo slightly.

Not sure as motorcycle instruments are sealed. But even if you could, you might find that if you calibrate for say 60 to be accurate you will push the error to a different speed, eg you might find it then reads low at 40. But if it’s only out by 3, that is well within tolerance, way better than my car which reads about 10 kph high at 100kph.

I use Tune ECU for the throttle bodies. Never checked the speedometer just figured as long as the Harley's are in my rear view mirror i'm good.

That reminds me of that joke.

Not since 2nd gear ......

Adjust speedo in tune resave then install. The odometer will be off by the correction amount. Or get a tire 5.4% taller

Thank you, I was starting to wonder if my very good results with Dyna Beads over the nearly 50,000 miles I've put on them with my Harley were just my imagination....... considering the several less than positive comments I have received. Thanks again!

Bridgestone Exdra max?

Like that donkey riding Sonny, I found the 240/55R16 Exedra Max corrected my speedo.
It is now right on with my GPS and police radar.

Yea found out the hard way right on with the police radar.
