My sons father passed away friday and we are getting his "old" bike running for a memorial ride. My question is.....It is a 1950 Panhead that still runs on leaded gas. Is there something we can add to the gas so we don't have to convert it? It is 99% original parts and we do not want to change that. My son is taking classes to be able to work on it himself after the initial fixing is done. (cuz dad said if you can't fix it you darn sure ain't riding it) So we just don't want to mess anything up until he knows what he is doing. thanks so much for any answers!!!
