Speedo Drd, Speedometer and Odometer Accuracy-Speedo Healer/drd
I have not seen a Speedometer correction thread when I searched just now.
I did read another thread that mentioned the devices commonly used to correct ones speedometer. @sendler and @choneofakind I noticed that you two were discussing how adjusting your speedometer to be accurate can sacrifice the accuracy of your odometer. Are you saying that if I take a bone stock bike that has a speedometer that is 4% optimistic about speed and I ride it at 62.4 mph for one hour the odometer will record only 60mph? How have people determined that the speedometer is inaccurate while the odometer is accurate???? Specifically my GSXR750 speedometer is reading about 13% faster than my bike is traveling when compared to GPS, and Automobile readings. It reports 10% above my gfs ninja 300 I bought a DRD and installed it...... Great product, cheap, quick install, simple directions, and seems to be effective. I have only taken it out once since the install a few minutes ago and it seems to be accurate against my Iphone GPS speed reading up to 80mph. I have not gone faster than that at this time and will verify its accuracy against other methods of speed measuring. Car, GPS and what not. Did I screw up my odometer reading by correcting my speedometer?? If I change sprocket sizes and use the drd to correct that it should correct the speedometer and the odometer in equal measure?

Speed sensor > speedohealer/DRD > displayed MPH > odometer. The DRD corrects the speed displayed thus corrects the odometer reading.

If my odometer reads from given speed on the speedo... then where the heck do people get an idea that DRD or Healer will throw my odometer out of accuracy.?

I know I'm missing a whole back story, but the only way it'll throw your odometer reading out is if it's not adjusted or calibrated properly to your gearing ratio. At that point your speed indicated would be off as well.

These two confused me-
https://www.ninjette.org/forums/show...69&postcount=4 https://www.ninjette.org/forums/show...30&postcount=5 These posts led me to believe that they know something I don't about the speedo and tach. (I don't know much.... I was just running with assumptions when I figured the tach and odemeter are one unit that function off of the same input signal thus probably calculate at the same rate..... )

Sounds like they are right for the most part.

The odometer and speedo are both run off the same electrical signal coming off of that sensor on your transmission. The speedo is often calibrated to read high, while the odometer is calibrated to be closer to the real distance. It's set that way. You can confirm/disprove this with your own bike with a GPS, or by the mile markers on some highways. The speedohealer type devices muck with that electrical signal, to basically slow it down or speed it up to change the speed reading however it is adjusted, typically to make it read more accurately. If you are lowering the speed shown on the speedometer, it's doing the same exact correction on the odometer, so if that was already closer to accurate, it will now read low.

Yeah. I understand the principle I just don't understand why they would produce them new with a discrepancy between speedometer and odometer calculations.
That is very annoying.
