What are the speedo adjustments made of? Are they just a resistance?

Not exactly sure, but they must monitor the sensor pulses and send them out at a different rate, so they must be a bit more than a simple resistor.

Variable Pulse Width in proportion to the speed your travelling. I have a speedo correction unit that I'm not using any more if you need one!

Almost every speedo now uses as Frank mentioned pulses for information. The main shaft will have what is called a reluctor that has a given number of high and low points in it. It will then have a sensor or magnet near the reluctor with an air gap of about .050 and as the reluctor passes by the sensor it creates an a/c signal in high and low points that the pcm counts as pulses. Usually they measure something like 4,000 pulses equal one mile and so many pulses a second equal so many miles per hour. All the correction units do is alter the number of pulses according to your desired change.

I slept at a Holiday Inn last night. :)

I bought the Dakota Digital from Chopper Steve (V.mod) for about $100.
Mounted it by tie-wrapping to the wiring harness on the left side of the bike just behind the rear cylinder and just in front of the storage pouch I have mounted there. It's positioned vertically with the "faster" button on top of the "slower" button.
It needs to be pushed up or down while traveling to change the speedo. I can operate it that way with my left hand without a problem and you can see it even when looking right at it.
