Quick question: I have a brand new 2008 Nightster with only about 90 miles on it. I'm following the "break in" period guidelines, going nice and slow and not pushing the bike at all. Do I have to wait until a certain mileage to do a stage one exhaust swap out? I was considering some Vance & Hines pipes. Even with the pipes, I'd plan on following the guidelines and break in the bike correctly. When is the right time for new pipes?
