I would start with posting some pics of the bike. an easy one to tell is the rear bearing carrier. A stock carrier has slots that run parallel witht the axial maybe 5. and after market carrier will have holes maybe 6 just large enough to fit a screwdriver in to for chain adjustment. An after market header probly wont have tabs for a heat sheild.

Yea what he said^^ Take the seat off and take the airbox lid off see if there is a certain brand of air filter. Pics of all parts of the quad would help alot
