I recently upgraded the speedo on my 2012 FXDB, my question is, am I able to sell the take off speedo? The new speedo says it "burns into the bike's ECM after 31 mile" well the take off speedo only has 25 miles on it. Is it "burnt in" from the factory or does it too burn in after 31 miles. I want to sell it but wouldn't want to sell something useless.

 

The mileage is in the ecm. It updates the speedometer.
