Hi czowner
Have you tried contacting this guy, his shipping may not be as much if he can get you the gaskets you need.

If he can't one of the Lifan Dealers here can get the gaskets for you, but the shipping may be high. A gasket Set from Athena for a CRF230 retails for $128.95 here in the USA, and I would not guarantee all of the gaskets are the same. I hope that this helps.
