'12 airbox mods?

[GMP]

Did you guys with '12s get the bag of Twin Air air box inserts, circular filters made to snap in a hole you cut for more airflow? What are they trying to say? You can see them on Lampkin's bike in the Erzburg photo. That airbox seems gappy enough, too much so IMO. I never had any indication of airflow issues, actually mine likes richer jetting than my last two with the same PWK AS I carb.

Its a beast now with:

JD Blue needle #4
45 pilot
180 main
AS 2 - 2.5 turns out

Real torquey, snappy, with a nice mid hit. Idles clean and starts easy.

All the missing lower mid has been found and then some. I'll do the head next month, no rush now.
