Rocket 3 Roadster Possibly Overheating?

This isnt the case, issue started way before, unless the fan turn itself backwards overnight lol
 
You can always get a hydraulic bike jack to get it upright. The manual recommends that before starting to fill the coolant system you crack open the bleed valve. This gives air a place to go as the system fills. It's likely the tech failed to do this, and the system has air trapped you can't get out until you open that bleed screw. Also, a leaking rad cap should be replaced, part number is T2100069.

Once you have the bike level (and stable) open the rad cap and then crack open the bleed screw (bolt) (located above the thermostat housing). Once you start adding coolant when full it will come out of the bleed screw vent hole. Tighten the bleed screw to 10 Nm. Top up the radiator and install the pressure (rad) cap. Then start the bike and allow to run until you see the expansion tank level rising. Shut off the motor and cool down to ambient. Check rad level when cool and top up if required. You should be golden, unless your thermostat or water pump isn't working.
