I bought a 92 KX500 yesterday for $400. Runs good, but the rest of the bike is junk. I bought another one last week just for the engine for a new project of mine (rmz250). So I really don't need this engine that I just picked up but the price was right! I see them for $900 or more (the engine that is) on ebay. What would a good price for me to sell this one for? Or should I just pull the engine, and hang on to it for a while just in case I find a KTM chasis to put it in.
