    This is a pretty straight forward installation. It took about 30 minutes. Here is an exploded view of the 2004 and up speedometer to start things off. Thanks Wild Steed Worx for providing the exploded view.

    2004 and Up Speedometer Exloded View.jpg

    Here is what I received in the mail:

    Dakota Digita BD 140 and 140 R.jpg

    The first thing you'll want to do is protect your gas tank from damage or scratches. I covered mine with a nice soft cleaning towel.

    Turn your handlebars all the way to the left (this provides a little more room to work).

    Next remove the two (2) Allen Head bolts shown in the picture below (see arrows). They are 5/32.

    IMG_1801.JPG

    Once those two Allen Head bolts are removed, the speedometer cluster will be free from it's mount.

    There is plenty of slack in the cable, and you'll need to pull some of it through in order to access the next Allen Head bolt that needs removed.

    Remove the below Allen Head bolt. It's a tiny one. I believe it was a 5/64".

    IMG_1802.JPG

    Once this bolt is removed the speedometer cluster can be separated.

    NOTE: There is a small spacer inside between the speedometer outer cup housing and the inner mounting bracket. It's number 16 on the exploded view above. You can see a small portion of it in the above picture.

    Next unplug the old speedometer wire plug below (yes that's the new one, but you get the point).

    IMG_1804.JPG
    Now unbolt the two (2) nylon nuts holding the old speedometer to the inner mounting bracket. They are 11/32".

    IMG_1803.JPG

    There are notches on the mounting bracket, so you can't mis-align the new speedometer when putting it back in.

    Once you have installed the new speedometer and aligned the mounting bracket in it's notches, use the nuts supplied with your new Dakota Digital speedometer. The installation instructions show nuts that are hand tightened, however mine did not come with those. Mine had 1/4" nuts.

    Once the mounting bracket nuts are tightened (careful not to over-tighten these), plug in the new speedometer wire plug.

    Now is a good time to turn the key on and check to see that the speedometer comes on as it should. No sense in buttoning it all up just to find out there is a problem and have to take it back apart.

    Now you have to re-assemble the speedometer face with the speedometer housing. Get that spacer I previously mentioned (#16 on the exploded view) in place and re-install the one tiny Allen Head bolt (careful not to over-tighten).

    Lastly, re-align the speedometer housing cluster on it's mount and re-install the two Allen Head bolts (again, careful not to over-tighten).

    Now it's time to program the odometer. The instructions do an adequate job of explaining this, so there is no need to cover those instructions. It only took about 1 minute though.

    Before:

    IMG_1800.JPG

    After:

    IMG_1809.JPG

    Now it's time to go for a ride and see if the speedometer needs to be calibrated. Again, the install instructions do an adequate job of explaining the procedure.

    I hope this helps some of you tackle your own install. Thank you.

    Nice write up and someone may buy the used BD unit from you if you want to get rid of it. I’ve got the blue Dakota and really like it.

    Did you set the dimmer on yours?

    Mine was intermittently malfunctioning. Thus the reason I got the new one. It would just flat out not work every now and then when I fired her up and took off. No speed reading and the odometer wasn't counting either when this happened. It was happening more frequent, so before my mileage got too far off, I decided to replace it. I figured I would just keep it for records purposes. Are guys wanting them even though they're malfunctioning?

    I haven't set the dimmer yet. Wanted to see how it functioned as is before changing it. Unfortunately it wasn't nice weather today so it'll have to wait till tomorrow.

    Some folks can get into it and “repair” as needed. I like the look of the digital. I will adjust the dimmer and service interval this week. Had not even considered it until I looked at this thread.

    Perfect timing on your how to! I am getting ready to mount mine in the ridgeback build. I bought a used speedo cup and it's missing the mounts. Great how to ! Thank you

    I too liked the look of the needle sweep gauge, but the malfunctioning was getting more and more irritating. When it's time to ride, I don't want to have to keep restarting until the gauge works. I just want to be able to hop on and ride baby!

    To follow up post install, I just got back from a ride and have to say that I really like the digital speedometer. Someone mentioned elsewhere that the sun will sometimes wash out the ability to read the gauge, and I experienced that today. It didn't really bother me though, as I am just glad to have a properly working speedometer. I still haven't messed with the dimmer though. Probably do that in the next evening or so.

    I bought the k9 with the Dakota couple months ago and I like it. My 03 never worked so just being able to check speed is nice and the rpm gauge that my Pitbull did not have is an added plus.

    Thanks for the compliment on the paint. I haven't come across too many with pinstripe paint schemes. Honestly at first looking at photos of the bike online I wasn't super crazy about the paint. When I saw it in person though....well my jaw dropped! I love the flame jobs too, may someday buy an extra set of tins and have a flame job done on them. Then I would have the best of both worlds lol. Paint and those 300 tires is what grabs my attention. Is there a thread where everyone just posts a pic of their bike? I searched for one today but didn't find one.

    I think that's a good idea! Should it go in show and shine or general?

    Start another for the new guys and the older ones who haven’t posted up in a while. Maybe in general...

    You should post a pic of your 06 and 07 Kevin.
