Manually set mileage?

I got a lightly used gauge cluster, and I would love to be able to change the mileage on the "new" one to match the actual mileage I have from the old one, so I don't have to add or keep track separately. Is this possible on the '82 GS750E gauge clusters? I couldn't find any information on it. Thanks!
 
It's possible, but they were made to be somewhat tamper-proof so it's a lot of work. Hard to describe but after it's done, I believe it will be obvious to anyone who takes the speedo out of the dash that it has been modified. Take a look at yours, you'll see what I mean.

If the mileage is not off by much, I'm pretty sure the odometer can be run backwards with a drill or something.

If it were me, I would just slap the new one on the bike and call it a day. When it comes to vintage bikes, maintenance and cosmetic up-keep are what counts, not mileage. If you want, you can always take a picture of the two next to each other for reference later (e.g., when you go to sell it).
 
The actual mileage is around 31,000 and the "new" one has 7,200. So it's off by a whole lot. If there is no easy way, then I don't want to tamper with it too much. I just wanted to see if there was a quick fix or easy way to do it. :/
 
You can unfold the crimp that holds the bezel ring around the plastic rim and remove then glass. Then take a pencil eraser and move the numbers. BUT theres a catch....ONLY turn the numbers to the next HIGHEST..never roll backwards. there is a little plastic tang that clicks into the gears so the numbers cant go backwards. Trying to go backwards breaks these tabs and its toast.

There are several threads showing the prying of the crimp and resetting the glass back on. When its open you can clean the gauge face with some Windex and do the inside of the glass too.

Huh. Today I learned something new. I'll have to give that a try on one of my junk speedos. Thanks, Chuck!

Have you ever tried this on a GS speedo chuck? Don't think it's that easy.
 
Why not just chuck the end of the Speedo cable into a drill and spin it til its where you want it? Same as the wheel spinning the drive gear and no risking breaking something on the cluster.
 
Its actually real easy once you do your first one. Can have one open in less than 10 minutes.
 
Would it be easier to take a drill bit and move the miles like your riding it?
 
60 MPH is 1 mile per minute. So assuming you set the drill, up and achieve 60 on the clock....do the math on how many minutes that takes and divide that into hrs....
 
Or you could just ride it and enjoy how smooth and powerful the old pig is with only 7,200 miles on it.
 
I changed my odometer really easy. Just gotta take care in doing it. The number barrels you can rotate individually by carefully moving the desired barrel to the side some and turning it slowly. they have a spring load on them. You can feel it click a little. Don't force it, just even pressure and slow. When I changed out speedos there was a difference of about 10,000 miles from my original mileage to the one I was installing. I got the newer one set exactly to the miles on my old one.

You can also swap out the odometers as well, couple of screws and they come off the speedo unit.
