I have a 2005 S2R. I put new Virgin gauges on my Ducati. The tachometer works without issues. The spedo is way off. I am not hitting 20 mph until right as I shift into 2nd gear!
The Guages have the black face such as the 6** series of bikes. Any help would be much appreciated!
Is it possible that my bike uses less magnets for the speed sensor than the new gauge?
right off the bat it seems the 620 gauges are calibrated differently. you MIGHT need to get a different rear wheel sensor, not sure. or you might just need to get the gauges calibrated.
you can check on the ducati omaha site to see if the rear wheel sensors for the 2 bikes are different. I assume the S4r also has a 17" rear tire with a 6 bolt 10 inch rear rotor?
there are speedo calibration kits on ebay, but they're like $80 bucks
Yeah, it's a pick-up number problem. 5 4 vs 6 pick-ups iirc.
My Gauges use the rear sensor that uses magnets instead of the mechanical wheel. I'm thinking it's a 695.
Is there an documentation that I can't find about how the rear sensor is setup. I remember reading about it on the old forum but it's not there anymore or their search feature sucks...
The spedo healers seem to only adjust up to 10%. I'm off by over 50%
Any other ideas?
Is it possible for a magnet to be bad on the sprocket? Or and the spedo sensor be bad but sill show a low mph instead of none.
If you put a gauge from a different bike that uses a different amount of pick-ups, and now your speedo is off, why fight the fact?
The S2R800 uses 4 steel posts on the rear brake disc as triggers.
The Monsters with double-sided swingarms (DSS) use the 6 mounting bolts for the rear disc as triggers.
You seem to have an instrument cluster from a DSS bike, as that would explain your 50% error.
Is it possible for me to drill out two holes and put two extra bolts on my rotor as a cheep work around?
Or can I put a rotor from a DSS Ducati Monster?
I also found a spedo healer (http://www.sprocketcenter.com/p/1119353/speedodrd-speedometer-calibrator---ducati.html) that goes up to 99.9% change. Has anyone had fhe with this?

I wouldn't bother with either of those ideas. You may just f' up a rotor, and it not work. Good luck fitting a 6 bolt rotor on a 4 bolt bike.

No FHE, but this would be the route I'd go first...
I had a theory of using Titanium bolts and then mounting the appropriate number of magnets.

I'ts possible to put two extra lumps on your rotor, but not very easy due to their location.
Rotor from DSS bike will not work.
I'd go with a Speedo Healer.

They're not magnets.

TI and Steel bolts have different magnetic properties right? isn't the speedo just a magnetic sensor?
The sensor has a magnetic core, wrapped with wire.
When the steel bolt head (DSS) or post (SSS) moves past the face of the sensor, it creates an electrical voltage/current signal.
The ECU/speedometer reads these pulses and calculates the speed.
The sensor cannot 'see' a stainless or Titanium bolt head, as they have, respectively, not enough iron or no iron.

ok so my point exactly. Ti bolts wouldn't be seen. so you could put the proper amount of another metal or magnet or whatever the sensor would see.

Back on the old forum I had remembered someone talking about this but it looks like the thread had been deleted.
In Theory I could put in two steel bolts. Would they be close enough to the sensor to be read?

i think all the bolts would have to be spaced evenly. so just adding two to the current four would not do it IMO
My red-neck friend suggested this work around for fixing the spedo [roll]

I'm happy to report that my spedo healer worked, in fact the spedo is now more correct than the orig [thumbsup]
What speedo healer did you use? Link?
I bought this (http://www.sprocketcenter.com/p/1119353/speedodrd-speedometer-calibrator---ducati.html)one
Maybe this is a stupid question, but how do you adjust this to be correct? What's the input?

I used my gps to calculate the real speed. ((GPS/spedo)*100) - 100 = percentage to adjust by.

There is a button and led on the unit. You go through a series of button pushes while watching the led to set the correct percentage.
I think I might get this because it is always a mystery what my real speed is.
