I know these were never intended to be used on the old 305's. But this is such a great source that I thought I would post this question here. I have a '73 Honda cl350 with constant velocity carbs. The diaphrams look good and are probably still as flexible as they were brand new. But my question is if there is anything out there that is recomended for conditioning or treating these diaphrams for exteded life of the rubber? Any thoughts? (Sorry for the non-305 post)
