I've got several Chinese pit bikes and quads, and I've been buying spare parts from MotopartsMax for 5-6 years. They have great prices on generic Chinese pit bike parts. You have to know what you're buying with many of the parts, but it's not rocket science. My most recent order arrived a few days ago. About $100 got me 3 stators, 3 CDIs, 2 replacement clutches, 3-4 fuel pumps, a set of brake pads, and half a dozen fuel petcocks. You can't beat it. When one of my bikes breaks down, I have a good stash of parts to get it running again.
