rebuilding pit bike

[Lomar84]

Hello, new member new to working on pit bikes as well. Looking for advice on where to find parts. I have a 2004 Flywing MX100 that i was teaching my daughter to ride last year when she wrecked into a tree. I am realizing that parts are hard to come by. Any advice on where to order parts? or is Ebay my best option? I am looking for forks, handle bars, front wheel, front break lever and cable, governor, possibly a carburetor as well. Any help and advice is greatly appreciated!
