maybe in the manual it has a lot of information on how to maintain the bike. i put my seat on today just to see how it fits.take the back seat cover off, theres two screws in the inside that hold the new blades in the center on, after you take those out there a 3rd 1 in the middle you have to lift the plastic up a little to see it, then the blade slides back an out and your seat fits right in.
