My temp gauge sits between the bottom and middle of the gauge when the keys turned on, I ran it for a while and it didn't seem to move? It was working previously.

I replaced the radiator but I don't think that would cause a problem.

Any ideas?

 

What about the sender unit in your radiator..........?
Did you connect the wire ?

 

The device on the radiator is a Thermo-Switch and only turns on the Fan Motor. The Thermo-Sensor that controls the Temperature gauge is located on the right rear of the cylinder head kind of behind the Thermostat housing. There is one wire going to it, it could be loose, or a loose connection into your gauge cluster. There is a proceedure in the manual on page 18-15 for testing the resistance of the unit at given temperatures.

 

I pushed all the wires into the adapter and it started picking up in temp while the bike was on so thats good. But the needle wont drop below a quarter of the way up, even after the bike sat overnight and it was 50 degrees out.

 

I doubt this is the problem, however if in the rarity your temp gauge is broken or not working properly I have an old temp gauge for ya to replace it with which works fine.
