i think, knock on wood, my '72 is pretty well sorted mechanically and electrically. i'd like to clean the exterior to make it look like it's running right now. fuel tank and side panels are fresh paint, new pipes, fenders and mufflers cleanend and polished, just a few chrome pieces to come off for cleaning. how do to clean the motor, trans, primary, etc. i'm stocking up on scotch bright pads, tooth brushes, fine steel wool, etc.. is there a safe product that sprays on and off removing at least the major grunge? i suppose the best time for this when the bikes apart but i see no need for that anytime soon. this is not intended to be a show bike by any stretch, just a good, clean, well running example of a classic bike. thanks in advance, rick
