New guy here. Traded in my 2000 Ultra Classic for a 2011 Kingpin today (1900 miles and like new). Love the bike but have a ton of questions-- I don't even know what they are, but I am sure they will be coming. I don't have an owners manual, so are there some things I should know right offhand? I will be looking to replace the exhaust. What is the best bang for the buck? Also, is there a quick release windshield and who makes the best ones? I figure you guys know best.
