Street Bob Speedometer replacement
Street Bob Speedometer replacement
I have a buddy with an 08 Street Bob and the odometer display was cooked. I assume the bike spent many of days outside in the sun. Other than that, it worked fine but he wanted to be able to see the mileage and trip(s) so I found him one on eBay. The part number was 67478-04A. When he got his out, it had a part number of 67478-04B. The problem is, everything works except the actual speedometer. I probably got screwed on the deal but just in case it's operator error, was wondering if replacing a speedometer in this year/make/model bike is plug n play or is there some sequence required to get the bike to recognize a different speedometer? We tried disconnecting the battery but that did nothing. When you turn the key on, the speedometer needle dips counter clockwise for a few seconds. Turn the key off, wait a few a few seconds and it does it again. Any suggestions? Or did I get a junk speedometer?

I know there's a specific sequence on the newer Dynas to transfer the mileage from the bcm but can't say for sure on the older models. Aside from that, all the functions should still work. Not sure if that model has a speedometer cable or if it's digital but if it has a cable start by checking that. the new part being AB just means it superseded which means they just made a change to that part. It's still the correct part of all of the numbers match. I could be wrong but it sounds like you got a junk speedo assuming everything is connected correctly.

Ahhhh... nope, not even remotely accurate or close. The gauge isn't plug and play and locks to the ECM of the bike it's attached to after 31.1 miles.

I'm betting on a locked gauge. Once it's locked to the ECM it's forever a part of that bike; you can't just put it in to another bike and have it work. Was the gauge you purchased new in box? If not, it's a paperweight.
To change out the gauge on a pre-CANbus bike you need to have the old gauge mounted; you connect the new gauge to the data link connector with an adapter harness and hold the new gauge as it copies. Once the copy is complete the old gauge can be removed and the new gauge installed; then you ride the bike 31.1 miles to lock the new gauge to the ECM. Permanently
Edit: Forgot to ask. Does anything display on the gauge? Does it say "VIN ERR"?

For most people that's what plug and play means. No user interference required. You plug it in and it starts working.
For some others it maybe too complicated, apparently.
BTW, OP is taking about speedometer, and speedometer doesnt get locked dude, read again.
