Love working on my Harleys. Even the fuel injection is easy. I think it makes it simpler. Carbs can be a real pain sometimes, although the CV carb on the later Harleys is a dream. I've set them up to run on everything from Viragos to generators.
600 dollars for an oil change on a 2014 Ultra Limited... Um, no thanks. If I can't change my own oil, time for me to quit riding.
