I am listing this for a friend. This is Mike McAndrews Championship Tag Jr. kart and engine that won the 2013 USPKS national Championship. It is a Birel RY-30 s-4 Chassis with a MY-09 engine.The engine was blueprinted by Franklin Motorsports. The kart has a mychron 4, 2 temp gauge on it. Mike is moving up to SR tag and that’s the reason for selling. Would consider seperating. $4000 Call Brian at (262) 689-5742.
