Sure could use some advise guys...
I have found fiberglass muffler packing "plugs" collecting right behind the spark arrester screen on my 450 exc, way too many times. I even road the bike for a few weeks without the screen, thinking that it will just blow out the residual fiberglass (from the fresh repack that was completed 10-15 hours ago). Did I somehow pack the muffler wrong? Maybe I put too much masking tape on to hold the packing in place for ease of reassembling it? I would take the muffler apart... but man, I did such a good job of sealing the muffler with heat rated silicone! Anyone else have had this kind of issue? Is it normal for a fresh repack to shed for a bit? My previous bikes did not have a spark arrester screen system like this one has. The photos show a collection of fiber after an 80 mile desert ride.
Thanks for any help,
