Start with the seat bucket, there's 4 allen head bolts and 5 10mm nuts holding it on, let the piston just hang from the seat and tie the seat forward with a bungee cord. Watch when you lift the bucket out and disconnect the light and charger wires on the right side and you'll expose the whole engine compartment. It's easy to get to the carb and filter from there.
Well, easy as getting anywhere on a scooter.
