Manually set mileage?

[Anthony]

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.

[chuck hahn]

Dozens of them..and some Yamaha and Kawasaki ones too.

Heres a thread showing the bezel ring after Ed had recrimped one he had done..dont know if he has any pics of the actual uncrimping though.

I recall someone quite a while ago had posted pics of them prying the crimp up on some though b ut I cant seem to find that thread anymore.

This one shows the screw driver application about 5 or 6 posts down.

Just ride it 23,800 miles.

[chuck hahn]

Its actually real easy once you do your first one. Can have one open in less than 10 minutes.

[Anthony]

Would it be easier to take a drill bit and move the miles like your riding it?

[chuck hahn]

would take a heck of a long time I would think.

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....
