I wonder if pulling my outerwears off my k&n would help.
I pulled the outerwear off my UNI. No difference.
I'm using a new spark arrestor, genuine mikuni jets, pulled the pipe and cleaned the small amount of build up in it, same air filter w/ same oil (tried with and without outerwear), and been using the same fuel for the last 3 or so years. Only thing I haven't changed are the reeds, which I might as well swap out at this point.
If the reed change does not fix the problem. Change the spark arrestor to a straight through type of muffler. The new spark arrestor may be slightly more restrictive. A slight increase in restriction will often require a smaller main jet to stop the misfire at 3/4 to full throttle just before it is usually time to shift.
