Your speedometer and odometer are independent of one another as far as calibration goes but if you have just had your transmission repaired or lifted your truck and put 36" wheels on it, chances are it will not be calibrated any more.
The only way to have a speedometer calibrated is to take it to a certified speedometer repair shop and let them do it.
A couple of alternatives:
1. Have a friend in another car signal you when he reaches a predetermined speed.
2. You can get a rough idea of how far off it is by bringing along a friend with a watch with a second hand, a pen and paper to record your odometer while you drive. Go to an interstate and use the mile markers. Since you aren't sure if your speedo is correct, follow someone or stay in the right lane and drive fast enough so you aren't creeping along and tell your ride to record the mileage - as you pass it, call it out. Drive at least ten miles and call out the end mileage. Divide 10 by the difference between the end and start odometer readings.
If you start at 12,345.6 miles and end at 12,353.2 your speedometer is only 76% accurate. If you still have a gear in the transmission, you have to pull it out and count the teeth. GM 350 auto trans can handle gears from 18t to 24t, 700R4 trans gear range is from 34t to 45t. Fords go from 16t to 23t available from motorsport. Both GM and Ford make gears used in manual trans' that are cut opposite to auto trans gears. Chrysler also has a wide range of gears but it's been a while since all gears were available from the dealer.
Divide 100 by this number, that represents roughly what each tooth is worth percentage-wise. To make your speedo faster, subtract teeth. More teeth makes your speed go down. This holds true for all makes of vehicles.
3. If you have an electric speedometer (chances are you do) there are too many ways to list but chances are your PCM will need a software change to correct the speedo.
If you drove ten miles and the odometer says ten, then you should be able to drive at 30 MPH non-stop for two minutes and your odometer should have recorded one mile.

Is there a fix for a Kawasaki Vulcan speedometer which reads low speed?
It will depend upon your bike. Older vulcans used a mechanical speedometer (a cable runs from the front wheel to the back of the speedometer. I don't know of a way to adjust these. other than changing your tire size (not recommended). Newer bikes use an electronic speedometer, and for this there is a fix. A little device called Speedohealer. It took a few tries to calibrate, but now my '07 1500 reads dead on. http://www.xtsportbikeaccessories.com/SpeedoHealer_HealTech.html
