While cleaning out one of the sheds on the old mans farm, i found a DG head for a YZ125C. Its not a Radial head but a Porcupine head, with DG cast into it, in a DG box and all marked yz125 Porky. i dont even remember DG making Porky heads ( something to do with getting old maybe), what is this worth do you think? Its in mint condition, and only looks like it has been on a bike for a few minutes, not even any carbon on the combustion chamber. Also found a pair of wheels for a 75 /76 KX400, complete with backing plates and cush drive , and rear brake pedal. Any ideas on value of these?
