I think they all have that patch
I have that on my pipes also as every one I have looked at does.....I think it is a rust preventive covering a weld that connects the tips ........All I can figure .Hello Forum:
I am buying a 2014 Valkyrie F6C on Monday. Maybe the forum could answer a couple of questions I have about the bike:
1. There is a small, what appears to be, a lead patch to the top interior side of the left exhaust. Neither the owner or the dealer can explain what that is. Does anyone know what it could be? I've attached a photo of the lead patch. It looks like a hole burned or somehow occurred to the exhaust and it required a lead patch. What could cause that hole and repair?
Pity they didn't tell him what they're actually FOR(!).. said that he'd shown my photo to his engineering department who told him that every new Valkyrie has one of those patches to each exhaust.
I did read somewhere that the engineers went to great lengths to get the exhaust note how it is so you might be on to it....or it may also be just a weight to change the resonant frequency of the exhaust.
