when you get bigger tires, or different rear end gears.
There is no speedometer cable. MPH is calibrated using a speed sensor. If your speedometer is not working, you have a bad speed sensor module.
Speedometer calibration differs depending on the vehicle and age. Some cars are calibrated by a technician with a computer program. Others require a gear change to drive the speedometer at a different ratio.
The speed should read fine with a GM speedometer, as the 110 and 150 are calibrated to go into the same cars with the same transmissions.
A different OD can effect the speedo accuracy, but unless it is significantly different from OEM you should not have to have it calibrated. If you do any speedometer shop can do it.
Different size tires and wheels. The factory size tires and wheels are calibrated with the speedometer. If a different sized tires or wheels are put on the vehicle, the speed can be off.
Yes, it's legal to have a speedometer that's calibrated in kilometers in the US. There's no law thatsays you're even required to have a speedometer in the vehicle. The law only limits the speed atwhich you're allowed to move the vehicle on the public thoroughfare. How you choose to monitorand regulate your speed is entirely up to you.
I don't think Harley has a retro fit kit to do the change, also the speedometer might not be calibrated for the XL, this speedometer runs off a speed sensor on the transmission and is sensitive. This speedometer can only be used on the FXDWG ('95-'98) Softails ('96-'98) FLHR/I ('95-'98) using retro fit Harley Davidson Part # 67418-99. Hope this helps......
The car wheel size has to be calibrated with the speedometer because the circumference of the wheel touches the ground: ergo a huge wheel like those found on heavy machinery can spin slower because with each revolution it covers... say 5-10 feet.
It is calibrated by puttin it in some ice.

No you need to have your speedometer calibrated. over size tires will make your vehicle read a lower speed, but nit more than a few miles over the limit. There are NO EXCUSES
