How screwed am I?

[pekingduck]

On all Honda motorcycles (with the possible exception of the new Gold Wing), the odometer reading is burned into a chip in the actual meter assembly and is not changeable. The tripmeter zeroes out when the key is shut off or power is disconnected.

Do you mean the tripmeter resets when you switch off the ignition? Mine doesn’t.

Sorry Cormanus, you're right. I meant to say if battery disconnected or meter unplugged.

Tripmeters (and radio stations on factory radios) will retain their settings, and clocks will keep time if the ignition key is just switched off, but will reset if the battery or the meter assembly is disconnected.

On Hondas, there is a battery backup wire (red/green) that does not go through the key switch, and always maintains a small amount of current draw for the memory for tripmeters and clock (and radio stations on factory radio models).
