i have a 1981 yamaha mj50 towny . that being said, it needs a top end kit alittle over stock. heard to find for a towny. I was told that a jug from a towny would work on a qt50. If i used the towny exaust. If true ? I should be able to use the qt50 exhaust on the towny? Was told the port is a little off. that is the only difference . What do you think? Yes i know some of you out there don't like nopeds but they are out there. So get over it. Thank you for your time.
