I don't look in on this group often but I need more info. Is it an engine noise or some kind of steering noise? If it's a knock from the motor, you may have over reved the damn thing. If so the noise will speed up with the engine being reved. In this case you may have a bad wrist pin on a piston! If it's under warrantee take it in A.S.A.P! Don't tell them about the Race!
