Muffler issue

[vlxk]

Hello guys,
I'm doing end of season maintenance and repairs on my 78 1/2 C2 250. The OE muffler has something rattling around inside. Have any of you cut the can open and cleaned out the guts and rewelded the hole?

Its probably the perforated core rattling around inside.
If so you may need a new core
They can be taken apart at the seams to rebuild but its a lot of work, they can be chopped in other ways but will always look like they have been chopped so it depends on how fussy you are.

This bike is a racer so I'm not that fussy about something like a muffler.

The core is intact and secure at both ends. It sounds like there are a couple of small pebbles inside the muffler.

I wonder about cutting the end off in a way to make the muffler packable?
