Bought a '05 1800 last week. Going over it there is a loose baffel vibrating in tbe top (stacked) pipe. Don't know the brand ,but they are black. They are not V&H. Anyone, what would be the best way to secure that issue,to stop the vibrating? Going over the bike to get a baseline on fluids, and routine maintenance as It came with no records on the history of the bike.
