If you are early in the moped craziness and say u r building a traditional 70 cc Athena build but not yet ready for ditching the decomp or on a budget etc this is the head for you. This thing seals and the build screams. But remember the fins are Hobbit find so it's not going to be the final resting point of your hobbitdom but it will get u there. With the decomp I'll sell it for $30 plus shipping. This is the real deal. One of Graham's best early creations.
