I just got new pipes for the old girl. I was thinking of putting on the pipes myself and having a mechanic do the stage kit and retune the carbs. How hard is it to change out pipes and is the stage kit doable by an old shade tree mechanic turned computer hacker?(ME) I got V&H, the pipes on the bike are stock, but they go down both sides, the new pipes cross over and come out the right side. These are supposed to fit though. Any help?
