My 67025-96 electronic speedo is toast on my 96 FXD. Options for replacement seem limited. Drag Specialties is where I'm leaning. I have a 95 Sporty that also has a failing speedo, My understanding is this era was prone to failure, so a used oem isn't an attractive option, I have a used oem from a 2000 XLH Sporty, but because of the different gearing I dont think it would work accurately in the FXD.

What is the move here?

 

Can you review needs and clarify wording?
There might be a viable solution but wording requires some guessing.
It reads like you might have a 1996 FXD..basically a Dyna model.
The speedometer is electronic and you report it as part # 67025-96..guessing you read that from bottom of speedometer and did not just get # from a parts list.
Keep in mind that unless you are the original owner then perhaps speedometer could have been changed.
That factory unit basically uses a speed sensor and the odometer is LCD instead of the little wheels.
Is that a 5 inch tank mounted speedometer?
What does "toast" mean to you?
Is the LCD screen for odometer leaking and smudged?
There are some places that have been reported that will replace just the LCD screen.
Basically you remove about 4-6 wires with a wrench, ship, a shop replaced LCD and then install it back on bike.
*If it is just the LCD then perhaps that is the cheapest option.
Does the needle function? Does it function correctly?
Does needle function but not odometer? or the opposite?
The above can help to rule-out speed sensor too.
Or is nothing on speedometer working?
Sometimes removal of speedometer and review of the bottom of speedometer will quickly reveal a smoke mark in one of the holes when you flip it over and look at bottom of speedometer.
*Have you tested the voltage on bike at idle, high idle?
Reason: A high voltage situation or somebody jumping the bike from a running vehicle that has a compromised charging system can destroy a speedometer quick due to an overvoltage situation.
The situation with your unit is that it is a hardwired unit and the aftermarket units and just about any updated unit requires a simple to install sub-harness (about $65 US dollars).
The sub-harness updates the unit to the electronic plug style.
So with the limited information:
Check and confirm charging system first. It would be useless to fix speedometer and break it again due to a faulty charging system.
Then report what exactly is not working.
Then decide if it is the speedometer.
Then review options.
Note:
A used speedometer of that ERA will just report whatever is in the actual speedometer...15K used speedometer will read 15K.
A brand new one starts at 0 regardless of the miles on bike.
In addition to the sub-harness a Dakota Digital speed adjustment module is sometimes required if the speed reading is incorrect with the replacement unit.
Basically plan on the Dakota unit if you are going with the sub-harness already because it will be an updated unit.
Keep in mind that miles per hour(needle) is related to odometer so if the needle reads 10 MPH high the odometer will be incorrect too.

 

Just go with the Drag, if you want to spend money go with a Dacota Digital, if it's electronic and not analog there's no direct gearing
it's all electric.

 

I’m not sure what a replacement speedo costs but I’m assuming $300-$500.
At that price it may be worth looking at getting your original speedo rebuilt. These guys do good work according to a guy I work with.

im - you are way overthinking this. I've already done the troubleshooting, so I'm good there. The speedometer needs to be replaced or repaired.

The part number I gave is correct. It is an early electronic version, which as I understand it, are prone to failure. I believe the sensor is good. Turn signals and cancellation work. For the curious, the speedo dial jumps up to 90 mph and shakes and stays there whenever the bike is powered on, running or moving or not. The lcd odometer is not showing. The trip mileage lcd advances 1/10 mile every once in a long while. It shows approx 24 miles after my 4000+ mile trip.

The Drag Special replacement doesn't fit my 1996 Dyna as far as I can tell, too early of a year. I did look into getting a 1995 Sportster electronic speedo repaired once at one of those repair houses, and came up short. Forget why at this point.

Compatibility seems to revolve around the magnetic sensor reading teeth on a gear in the transmission. Hence, different gearing setup, different math, different speedo model. They basically all work the same, at least around this era. 12v and ground fed to speedo to run the lamps and +/- 5v speedo electronics. Signal wire from the transmission sensor is fed to the speedo, which converts it to dial movement. Which pins on which connector aren't a problem, I can rewire/splice any of that if needed. Hell, if you pull the sensor out of the transmission on a working bike set up, and place it close to spinning metal fan blades or a drill chuck, you can make the dial read mph. It's how many and how fast the pulses are read to provide an accurate mph reading that is the compatibility issue I believe.

Given that, the 2000 Sportster used speedo I have will physically fit, and I can wire it up correctly if I have to, and the dial and odometer will operate. But I don't think it will be calibrated for the Dyna to read accurately. Different transmission gearings. And there lies my center issue.

 

If speed pulse is your only issue.
The Dakota Digital speed adjustment module mentioned earlier might be worth research to address a signal pulse concern.
There are other similar speed pulse adjustment units.
Basically those types of units permit the control of sensor pulse up or down.
The size of wheel/tire or gearing would then basically be a non-problem and pulse/speed adjustment against GPS speed reading would get speed/distance accuracy very close.
The adjustment modules generally connect inline between speedometer and speed sensor.
Just conduct your research to see if that will work for you.

For diagnostics it is sometimes difficult to understand variables since motorcycle can not be seen, general history is an unknown and diagnostics performed by poster are sometimes not completely known.
It does read like speedometer is not functioning correctly but consider double checking possible triggers.
For example a bad voltage regulator or an over charging situation are known speedometer fault generators and sometimes speedometer destroyers.

I wish you well in seeking a resolution.
Hope you return with your solution so that others might be able to read and solve a their problem quicker in the future.

 

So to follow up... I put in a good working speedo and tach I had from a 2000 XLH w/ 10k miles on it. The 2000 had a NeutriK 12 pin connector, and the 1996 had one of those black boxy AMP connectors, so I went with a new Neutrik male/female set up. Most of the wiring is the same between the two, with a couple of ground and V+ wires being a little different. Nothing to worry about there. The tach only needed one signal wire feed up from the ECM. I pulled the dash lamps, cleaned the screen and replaced with LEDs. The speedo is audible checking itself on power up, and everything is lit up nice.

Everything works great, except as expected the speed is off. I will get an inline speed calibrator from Dakota or maybe the one from V Factor (which doesn't look waterproof).

I got the wiring schematics for both bikes, and just matched the connectors up pin by pin. I followed the 1996 schematic as the master, and made the speedo harness match that, since that is the bike it now is a part of. Many were the same anyway.

Not that bad, really.
