I have a 1984 gl1200a. Had new front tire put on. I took it 70 miles & speedo quit reading. It comes on intermittently. Any answers?

If you have the mechanical spedo....
Unhook the spedo cable from the front wheel..Rotate the wheel and see if the blade connector turns.This is coupled to the cable and then up to the spedo gear head...
my 84 had the end of the cable pull about 3/8" from the threaded coupler...it wouldn't allow the cable end to connect with the blade in the spedo gearbox completely.A bit of propane torch helped reset it.

My speedo has a digital display. Will this be the same?

Nope.The digital one uses a similar looking gear box on the left but is electronic and mechanical.
3 wires hook to it.One is ground,another is 5 volts and the third changes from 5 volts to 0 volts as the wheel is turned.This is tested first.
Problems can be a loose connector that it plugs into or a mechanical problem inside the gear box.
Test the switching volts first.
