Engine hot to the touch while idling?

hello everyone. i have been scratching my head on this for about a week now. selling my 2014 Honda Rancher TRX420FA Electronic Shift. i bought all brand new plastics for it and doing all the maintenance on it before i sale. when it is idling for about 10 min there is steam coming from my radiator cap and engine is super hot to the touch, can only touch it for just a fast second. it has a new Water Temp Sensor. New Thermostat. cleaned and flushed radiator. air bleeded the cooling system. did everything the service manual told me to do. does anyone have any ideas? how hot do these water cooled engines get? my fan does not kick on at all either only when i unplug the temp sensor. please any help with work. its a bad*** bike and runs really well. i am just done with the ES and go back to foot shift. it only has 350 miles. Thanks for any of the help!
