excellent description rjs, you described perfectly the 2 types of plastic pins. I'm not aware of Kymco using them on the smaller scoots? The fairings on my S200 all have tabs that lock into slots and have screws securing them. (except the instrument panel / headlight cover, that one is a BEAR!, and removes differently)
Can the OP be more specific in the description of what needs to be removed? Pictures help, too.
