What Don said ^^. The 2006 and earlier starters take more time to remove than the later models, but if you have a manual it's pretty straightforward. You won't need a complete starter, the actual starter motor is a high quality piece that rarely fails. In a Harley, starter failures are almost always a result of the overrunning clutch (drive) failing. You can buy a kit from Harley that includes parts you most likely won't need, or you can just buy the clutch unit itself for about half the price from the aftermarket. Back when I changed mine I just found the clutch unit online versus paying Harley for shafts and springs I didn't need from their kit.
