Have you checked to see if your fans are working properly? Does it overheat at slow speed or highway speed, or both? If your fans aren't working it would overheat in slow traffic while it would be okay at highway speeds with the wind blowing through the radiators. Radiators could be restricted (not enough coolant flow). Airflow through radiators could be restricted (not enough airflow to dissipate the heat). You could have a bad head gasket that would cause you to smell coolant from the exhaust.

If, when you turn the key on and the engine is cold, you should find that the temperature sensor is defective or there is a short to ground in the wire that goes to the sensor. Test, according to the service manual, the temperature gauge and sensor.

Ok but it still moves but it just high when I put the key when is a cold engine I just don't know what else to do about smelling antifreeze from the front but don't see any puddles I don't know if it's still running hot or is it leaking somewhere that it's drying up I don't know what to do

Pressure test the cooling system to check for leaks when it's all apart.

You use a pressure tester. It's a small hand pump with a pressure gauge, that lets you test radiator caps as well as cooling systems. You can pressurize the cooling system to the cap relief pressure while everything is cold and you can touch things without getting burned. The only trick is that you will need to have the proper adapter to suit the Goldwing radiator cap size. Probably a lot easier now that so many cars have micro sized radiators. Search Amazon for "radiator pressure tester", for at least 100 examples!. I believe Harbor Freight also has one. When the system is under pressure you can find pesky leaks that only happen out on the road.

Don't put more than 15 PSI as the system (hose clamps, water pump seals, etc.) are not designed to hold more pressure than that. Excess pressure could ruin a radiator or blow out a hose or seal.
