This is my 1st how to so go easy if it's crappy
I found a place online called Speed Gauge Customs ( http://www.speedgaugecustoms.com/suzuki-boulevard ) that makes custom speedo faceplates for our bikes. He does all years, including 2010 up with gear indicator in the tach. This how-to is only for the speedo, tachometer how to will be posted in the next couple of days.
Remove the bolt holding the gas tank to the frame.
Remove the single allen bolt from the chrome gas tank trim panel
Step 3 & 4:
Pop the 2 small clips out from the side panels, these clips are accessed under the seat in the same area as the gas tank bolt.
Pop loose the two small rubber retaining grommets from the underside of the gas tank on each side. This is critical, as these can break off if your not careful.
Move fuel tank back to expose the wire harness attaching the speedometer to the bike. Do so by slowly rocking the tank back towards the rear until you can see enough space to work the plug apart up front (near the triple trees and neck).
Once this connector is exposed, you need to separate it.
You separate the connector by prying this tab up and away from the male side and pull apart the 2 connector ends.
Remove the chrome trim bezel and speedometer by lifting the rear up (to clear the gas cap) while pushing the whole unit forward to release the two retaining nipples from these rubber grommets.
Do not pull straight up on the chrome bezel/speedo, or you risk breaking these nipples off. The unit must slide forward to clear these from the tank grommets.
Once you have the bezel and speedo removed from the bike, your now going to remove the speedo from the bezel by taking out these 4 screws. At this point I recommend working on a soft towel or other fabric, to avoid scratching the chrome or the speedo bezel.
Now you are going to open up the speedometer assembly by removing these 3 screws ONLY. Do not remove any other screws, or parts may move around inside and damage may occur.
Once those 3 screws are removed, you can separate the speedo into 3 pieces like so.
Now we are ready to remove the needle. USE EXTREME CAUTION and keep your fingers away from the pointer or you risk breaking it off. You can NOT get this needle separately! Pull straight out, with absolute minimal side loading or twisting.
Some of your needles will have the metal pin attached, and on some the metal pin will stay in the speedometer, this is NOT a problem. Once the needle is off, you will remove these two #1 phillips screws. You can then lift the faceplate from the speedometer.
Your almost finished! Make sure your new faceplate is approximately the same size as the original.....do not worry that the look may be slightly different, your just looking for basic size similarity and that the 3 center holes are aligned.
You can now lay the new faceplate in place. Make sure it fits snug between the 2 nipples, you may need to trim slightly but not TOO much! Make sure to use a SHARP knife. When you are happy with the fit, you can install the two #1 phillips screws and snug them up. Do not overtighten them! The OEM faceplate has metal reinforcement, this new faceplate does NOT so just snug them well but dont over do it.
Now you will take the speedometer to your bike and plug it in. It is time to calibrate the needle. Do not install the needle yet! Turn the key on and get the needle ready.
With the key on, wait at least 5 seconds so the sweep of the gauge is complete (I wait until the fuel pump stops running). At this point your going to install the needle PARTIALLY. Get it as close to ZERO as possible. You'll push it in ever so slightly, do not seat it yet. Then, follow the video below.
Before closing up the speedometer, give the top of the needle a good (but light) wipe with a lint free micro fiber cloth. When you touched it, you left behind finger prints and they will drive you insane to look at HAHA. I also give a couple blows to the speedo (mouth, not compressor) to clean out any debris or dust I may have created.
You are now finished with the install and you can reverse the removal process to reinstall everything.
