    Fleabay or buy from China via agent. [Some agent are good, some are so-so. Search this forum for the recommend one. China Post "SAL" http://en.wikipedia.org/wiki/Surface_Air_Lifted is a good option saving shipping costs ]

    It's best to get it off eBay as you are protected by buyer protection, it will probably take 3-4 weeks to arrive as it is coming from China. This seller can also sell you the gaskets, piston rings, etc separately if you need them, it might be a good idea to ask for spare gaskets and rings because otherwise you will be stuck without a bike for a month if something does go wrong.

    BE SURE TO ASK FOR THE FLAT PISTON!!!
