There is a 2003 model engine, 136 miles, with carb, on Ebay with the current price at $350.  It is in Williamsport, PA. and is a local pick-up only...no shipping.  If anyone is in need and in that area of the country get in a bid.  I have the bid right now but there is only 2 days left on the auction.  My plan was to buy and part it out, but if someone else needs an intact engine for a bike I will let it go.
