Odd noise from a 1995 R100RT

Question about a last edition airhead. I just purchased a 1995 R100RT Last Edition from the second owner. It has 13k miles on it and its in very nice shape with all bags and top case. All fluid have been changed and I have put about 250 miles on it so far.
My question is about a nagging noise coming from underneath the right side(brake pedal side) of the bike. Its sounds like a metal clang coming out of the catalytic converter. It only happens when engine is warmed up and at idle or low unstrained rpms. I have not adjusted the values so I am not sure if that could be the issue, but I swear its coming from the catalytic converter somehow.
Has anyone experienced a similar issue with a newer airhead. As a side, I have owned a number of older airheads w/o catalytic converters and never have heard this type clang noise before.
Thanks in advance.

Doesn't the output shaft come out of the motor right around that area? Perhaps something in the housing is a bit loose?

Sounds like something's loose within the exhaust system. Take it apart and shake it around to verify. Wait til it's cooled off though.

10 bucks

says its your right side muffler where the 2 bolts from underneath go through the tab into the frame weld piece.
One is probably loose just enough and the other not.

And also the clamp on the right side may be turned so that the bolt going through it is making contact with your frame.

Check both of those. If I am right I will send you my Paypal address so we can get the 10 bucks done real quick.

No converter on these babies... we pollute.

Goes without saying so let me say....do these things with engine and exhaust cold.

thanks folks I am going to dig into the exhaust system over the weekend to see if anything is out of whack.

Does it go away with the clutch lever pulled back ? Thought I would throw that in.
