see, i thought you were serious w/ the radiator....as my fears were realized...what you did not know was the 2014 103 Ultra has a radiator...just got unveiled
I once carried a radiator in the trunk of my Harley and it didn't run any cooler. Helped the car when I got it installed, but not the bike.
This is just a guess but did you have "HD coolant" in the radiator??? hey dude there goes your warranty....but not to worry the money you saved will go a good ways on your repair....
