Post by: darb85 on May 15, 2007, 06:50:48 AM
A. Yes I know I suck at Spelling

B.  Im at work, Can some one tell me what the Diameter of the gages is, someone here has some VDO Mehanical Gages that are bad ass here, LED lights and Allkinds of fun stuff.  Want to make sure they will fit.

Thanks

We have a Mechanical tach right?  2000 GS500.

"They are not cylinders. Min diameter is approx. 84mm, Max (not the outside lip) is approx. 87mm. Outside the metal lip is approx. 98mm."

89-02 have mechanical tachs.
04+ have electric tachs.

Electric tachs can be used on any GS. Just need to run a Positive, ground and signal wire. Connect the signal wire to the Black/Yellow wire that goes to the right coil.

Hes Got a really cool Tach with a LCD Mileage and Tripometer, How hard is it to convert to Electric Speed? more trouble than its worth??

I changed to electric speedo on my 97 since I used SV gauges. Used a SV speed sensor and made a bushing for it to fit the smaller axle. The SV axle is 2mm larger in diameter.

VDO makes a speed sensor kit do you think it would work? or should I just get an SV Sensor and Attach it to the VDO gauge?

I have no idea what it looks like or how it installs.

Mine is a sensor ,zip tied to the front fork , and a small magnet epoxyed to the rim , then size of the rim entered into the acewell , and done :D

i thought that , i had a post where i was gonna keep the anolog rev . but it was interfering with it , well mines got 2 types of a rev on it, a bar , or in numbers, and it flashes at the preset, which is 10.5k . just to be sure i dont blow the engine ,. but it flashes to tell you 2 change gear., im building a very interesting gs , so it helps to have something , that it isnt ment to have if u get my drift , i cant get that into it ,. ill buy a tiny rev sumwhere ,as i cut my clocks up 2 make a mount , easy , think i might sell the old clocks, hmm dunno tho

What did you make the bushing with?  Where did you get the parts, this some how seems easier.

Thanks

I used a stock GS speedo drive, pressed out the insert and turned it down. This made it simple for me since I have a hard time turning ID's on my lathe. OD's are no problem. The insert is a powered metal and turns easily. I left a shoulder (~1.5mm) on the new bushing to make up a small difference in width. This may not be needed on a GS since I am using Kat forks, which are spaced wider. I did trash the first attempt when it got snatched out of the chuck.
