OK...
We join this story as I've just received a replacement Yamaha muffler purchased off Ebay. It seems solid enough, but after the incident with my previous muffler, I'm hesitant to do this. My original muffler developed a rattle after a minor crash and so I attempted to remove the screw that holds the end cap on the muffler. (See diagram below.) That in itself was an adventure, (as is removal of almost any of the &^%$**^%!! phillips head screws on this bike.) I finally bought a "Pro-GrabIt" a screw extractor which I -highly- recommend as it does exactly what it claims with minimal fuss.
After removing the screw, I attempted to pull off the endcap (as shown in the diagram above) so I could remove the arrester, clean it, and peer inside the muffler with a flashlight to see what might be rattling inside. Again, rust had done its work and getting the end cap off was a real chore. Finally, when it did come off, it was without the arrester attached (as the diagram shows it should be. Instead, it was rattling around inside the muffler.
Fast forward to today. I have this new/used muffler and before installing it, would like to clean the arrester. But... again, the cap screw is rusted and will likely require the GrabIt to pull out. Then...here's my fear...will it be deja vu... the arrester in this one will again fall off and into the muffler? Should I take that chance?
I could just shake the loose crud out of this new muffler, maybe blow it out with some compressed air, paint it with some high-temp flat black paint, and put it on the bike, forgetting about cleaning the arrester. What would you do? Have you cleaned the arrester on your bike? Is it important this be done? How easily did it come out?
Stop me if this is a bad idea...I don't want to commit a second offense as an "arrester molester!!"
