Mine's fine although the baffle needs a more robust fixing.
I have just re-packed mine with this stuff:

Need to get the bike re-assembled and go for a ride to expand it all but the stuffing that came out was shot!
I've had this can three years and it was the only one availble back then (excluding the stupid money OTR jobbie that must be made of Ti!).
Now of course we have the MTC cans which look ace and great value - that's what I'll get if I need another one.
Most importantly I have not heard another Tenere that sounds as good as mine!!
