I just pick up really 1st Harley since I was a snot nose kid of 20. Now I'm passing the highway speed limit and went out a got a 85 FLH 80. On this bike I've come across something I have never seen before and hope that someone here might help me understand. OK on the front head the exhaust port has a pipe attached to it I'm sure a after market off brand or whatever. But there is only 1 yea ONE bolt holding it in place and there is only 1 hole to put a bolt in. From what I can tell I don't see anywhere that there ever was ore than one. The back port has 2 bolts and I'm stumped. Any advice or input will be much appreciated.
