As someone already pointed out, changing your cams does not effect the speedometer. Additionally, vehicle manufacturers (both auto and motorcycle) intentionally calibrate their speedometers from the factory to read higher than actually (some more than others). It's a liability issue. If you were to get a speeding ticket because the speedometer was reading too low, then you could take the manufacturer to court and say it was their fault.
ANYWAY, if you find it bothersome, you can installed a speedometer calibration kit. After my six-speed gear set install, my speedometer read about 15 mph low. My local HD dealership install a SIM-1 kit from Dakota Digital (which someone already mentioned):

Now, here's the rub. The way you calibrate it is, after install, you follow someone down the road who is going a steady speed and use the up and down arrows on the SIM-1 to calibrate your speedometer while it is in motion. However, since the vehicle you're following has a speedometer that's been calibrated to read higher than actual, you probably aren't going to notice a difference between it's speed and your own.
Hope this helps.

Good call. But, it depends on the update rate for the speed indication on the GPS. If the GPS updates the speed every second or every couple of seconds it could be used. My Garmin (which is an older one) doesn't seem to update the speed frequently enough to be used for a calibration. I suppose if I found a long flat stretch of road, set the cruise control on the vehicle with GPS, and got a couple of consecutive speed updates that were the same it could be used as a standard for calibration.

I posted a chart back in post # 6. Find a flat stretch of state highway and use the mile markers. Hold your speed steady, and time yourself between markers, and compare to the chart. Adjust accordingly. You can double check your settings when you come across one of those electronic signs that tells you your speed.
