Speedo Calibration 85 vs 140 mph

[Chromedome]

Hi, 75 and 85mph speed limits, flip,for real ? i thought they were all 55. I was in the US once an we had come down from Denvir through El passo an then headed North East to join route 66, anyway, the traffic where there was any in New Mexico was really steady at about 55, then this evening the whole sky got realy dark with rain clouds and it started to rain "heavy" to the extent visibality got real bad, the whole place was pitch Black with Lightening, everyone speeded up by a considerable amount, trucks especially, i never could understand it ! is this normal ?

For a while I think in the 80's there was a Federal 55 mph speed limit (gas conservation) . That has long since gone away. Typical interstate speed limits are 65 mph but there are places at 70 mph. Probably bit more (75 mph) but I don't think there are many posted limits at 80 mph.

What do you think I have in the attached photo? None of the 3 look like yours (other than the 9.5K redline). The last set came on my ED.

Actually all of the 3 in your photo look like mine exactly, 140mph speedo, 9.5K redline, see my post 7.
Don't confuse it with post 11 which are my '82 gauges, 85mph speedo and 9K redline.
I can't make it any simpler than that, not sure what makes you think I have a '82 tach on my bike, post 9.

Here is the picture from your post #7 and yet another picture of My 83 gauges.



I never realized that Suzuki had a 9K and a 9.5K reline for the 82 tach, but clearly both of your tachs are of the same style as the regardless if they are 9K or 9.5K redline; They are distinctly different to the 83 tach in my picture.

Both 83 gauges (speedo and tach) have the lettering on the outside of the mph/rpm tick marks. On the 82 the numbers are on the inside.

I just purchaced a new set of gauges and did not know myself that Suzuki had so many different tach and speedo combinations.My 82 has the 85 speedo and 9k tach.The set I just got (yr.unknown)has the 140 speedo but with a 9k tach also. Is that common? The set i just got was supposed to not have been dissassembled or messed with. Seeing that all of your 140 mph speedos have the 9.5k tachs makes me wonder. Hopefully I got a pretty good deal other than the 9k tach in that they are in almost perfect condition and the mileage was within 300 miles of the other and cost me $152.50 Or was that too high?Bottom line you are saying that regardless of the year, mph,and rpm they all seem to be closley calibrated and accurate and all of the cable gear drive units are the same. I'm still learning to post pics but if you care to see what i'm talking about the Ebay item # is 171028287712 and the tach looks exactly like my "82"where your pic in post #19 of your "82" has the red triangle but a 9.5k redline or am I making any sense at all lolol.

Yes they should all work indicating the proper MPH/RPM

BTW, IIRC I paid $250 for that nice set you see in the pictures and that was a couple of years ago.

Well now I know why I can't find a decent 140mph speedo setup: Posplayr has the friggen market cornered!

I'm pretty sure my '82 tach looks like Sedelen's with the triangle (not Posplayr's without it), but the redline is a meager 9K, not 9.5.

I put a set of '83 GS1100ED gauges on my '82 GS1100EZ, they seem to work well, didn't change out anything else. How accurate? at least as accurate as the '82 85mph gauges.

I think I figured out the mystery. The gauges (or at least the tach) above may actually be from a GS750 which had the "triangle" and the higher redline. Look at this tach: http://www.ebay.com/itm/SUZUKI-1982-...d90e52&vxp=mtr

Realize that I view the gauge cluster as one of the final elements of my ED build and so the difference between $150 and $250 is mute.
Also one thing to watch out for, the 83 gauges at least seem to suffer a condition where the face plates will distort and they don't lay flat under the glass. I think the tach on my bike was NOS or at least very nice replacement and it ended up curving. So you have to watch out for that.

Now I see what you're talking about! The location of the numbers, and it was pointed out also about that friggin triangle. Time will sort this out though. But, I bought them as a '83 gauges cluster and it does have that 140 mph speedo and 9.5K from wherever it came. I could be wrong but I don't think the 9.5K tach came out until '83 for the GS1100E. Could it be as a result of the welded crank modification that came out somewhere in the '82 model year?

I will take this pic of this '83 GS1100E as for what '83 gauges should look like, since I've read about this bike and know a little bit about it's history.

The attached picture is from an article in Cycle 4/82 reviewing the GS1100EZ. It shows the 9K RPM tach with the 85 MPH speedo. If anything I would think the GS750 would have a higher redline but I don't know.

Here is another article from 5/82 attached shows the same gauges with 85 Mph speedo and 9K tach.

I scanned both articles for what they say is the redline but have see neither that or the rated hp.

Here's some pic's of a pristine '82 GS1100E, it's got a good shot of the gauges,
the only difference in my two gauge clusters is in the red line, one at 9K and the other at 9.5K.

He also has a really nice '83 GS1100E, as well with lots of other bikes to include other GS's.
Must have lots of dough.

I understand he pickup a some of his bikes at steep discounts but he certainly has a collection that is for sure. I used to scan him site but have not been there for a while. I think he is a member here as well.
