I have an import 2008 F650GS Twin. I have been considering replacing the KMH speedo and clocks unit for a MPH one. There are plenty on fleabay. My question is where is the current mileage of the bike stored - in the clocks or the ECU? Do of I for a set of clocks from a bike that has 60k miles to my bike with 2k miles what will the mileometer show? BMW dealer has been not very helpful here! Thanks in advance for any help.
