2003 jinan qingqi qm50qt-3e scooter help?

I just bought this 2 stroke scooter a few weeks ago and it needs a little work. the guy before me caught part of it on fire and melted some of the plastic. I know that i need a new fan, fan cover, spark plug, air filter, ignition coil assembly, and cylinder fan shroud. I also need to replace some of the plastic body parts, and need a new floor mat. Does anyone know where i can find cheap parts for this scooter? The engine is a D1E41QMB. I'm looking for factory or aftermarket parts. i'd prefer aftermarket so i can get this thing to go a little faster than 35mph. I'm located in Los angeles, so if there are any shops that would carry these parts i'd like to know about them as well. thanks
