How long have you run the engine after changing the thermostat and sending unit? If it's not very long, you may still have a trapped air bubble in the cooling system. The reason that your gauge will read hot is that there isn't any coolant in this location to remove the heat from your cylinder(s). If your thermostat doesn't open, the air bubble will stay trapped in your engine. Since you said that your radiator isn't hot, I would guess that your thermostat hasn't opened yet. I think you need to run your engine longer. Maybe even take the bike for a short ride for 5 or 10 minutes.

Was the bike doing the same before you installed new units?

Sounds like 7volt regulator might be putting out too many volts. This powers the fuel and temp gauges.

Underneath the left shelter access panel. You can get replacements here, if that's the problem.
