Hey guys. New to the groups, and to the world of HD. I just purchased a brand new 08 XL883 Black/Chrome. Absolutely love the bike. Being new, I have a couple questions. I read through the manual, and I know I am going to take the bike to the dealer for its first service, but will probably do my own after that. I was fairly impressed with the stock exhaust, has a nice rumble to it, though I would like a bit more "harley" sound . What are the best slip ons to put in place of the stock mufflers? Do slip ons require remapping of the injectors? Void warranty? or hurt the bike overall? Second, I have about 60 miles on it so far, and the dealer/book said engine break in is for the first 500 miles and basically said not to over rev the engine or let it bog. I'm assuming he means like 20mph in 5th gear).Is there anything else I need to know? I'm sure I will have more to ask later, but that's it for now, need to go ride!
