Wayne, I don't know of such a device for the unit to read the hours/miles at this stage. Going forward, however, I would just pick up an hour meter online and install it. There are numerous videos showing how to install hour meters online (simple wrap around the spark plug wire) and mount it somewhere where you can easily see it. Also, you can download the complete service manual for that unit from here, see the first thread listed, Honda ATV Schematics / Manual Help - Honda ATV Forum
