Installed my new Kaw exhaust gaskets, along with wrapping the sections of the pipes where the connecting pipe (degoated) goes from the exhaust pipe to the muffler. Really easy process, and it sounds much better. I will try to make some more adjustments on the fuel/air adjuster to see if that eliminates some of the backfiring... I got the tape from Advanced for like $4 a package. Takes two packages. Was impressed with the ease of this low-level project...
