Speedo info

[TSM64]

This might have been asked already, but if I upgrade to bigger tires what do I need to do inorder to adjust the speedo so it shows the correct mph?

Take a long trip and check your odometer against mile markers on the highway or a GPS. Note the difference and figure a percentage. Mine is off 7%, odometer and speedometer are off the same amount. Figure out what speed you're really doing when you look at the speedometer. Cheap way to do it.
