There's a lot of good parts on this bike for the money and I believe it's a Honda 50 motor. It has the epa sticker on the flywheel cover. Motor looks clean too. Anyone near Oakhurst, CA? Might even get it cheaper than the BINP. http://www.ebay.com/itm/GAS-MOTORIZ...369?pt=LH_DefaultDomain_0&hash=item23347c4b71
