ok I get it. your tires rotate the same number of times per mile no matter how fast the speedometer translates the rotations. im retarded.

I think you get it. A speedo and odometer are both run from a single signal source that counts off distance traveled. On a set of digital gauges like we have on our bikes it is most likely an electronic pulse that represents a unit of distance. The odometer counts each pulse and adds them all up to measure how far you traveled. The speedo uses the distance counted during a period of time and divides distance by time. That is where we get miles/hour or Miles per hour. Yamaha and other manufacturers have decided to add a percentage to the actual speed in a feeble attempt trick us into slowing down but for legal reasons they make sure the odometer is correct. On our bikes the speedo is high by ~10%. If you correct the speedo with a speedo-healer you lower the reported speed by 10% by cutting the number of pulses sent to the gauge by 10%. This fixes the speedo but now the odometer counts 10% fewer pulses resulting in your odometer being low by 10% and making your gas milage appear to be 10% lower in the process. Please forgive my rambling Physics and Math lesson. I hope someone besides myself can follow it.
