DOH !!!! For some reason I thought he was talking about the Black plastic
cap over the diaphram !!!! that would really make it run like sh*t !!!!!
Didn't think about the cap over the pilot screw....I've got the one with the
knurled end and love it.

Drill the cap.. EPA cap over the "pilot circuit screw" bottom of carb
closest to the cylinder.
I used a small drill, then started a small sheet metal screw into the hole,
and used pliers to pluck it out, then since carb was already turned, turned
the screw in to a "soft" seat and backed it out
1 and 3/4 turns. (thats close enough most times)
Hitting the sweet spot involves burning fingers without proper 90 degree
screwdriver like tool, but warmed up using a handmade tool, I turned screw
in till it ran crappy, then tracking rotation backed it out till it idled
crappy... then turned it back in HALF way.
Typically about 1 and 3/4 turns from a soft seat is pretty, well close
enough for a KLR.

Will make cold starts ALOT easier....
Set pretty lean for emissions.
