OK, still ain't quite right on the Eric Gorr KX special. I mean it is very good, just not perfect yet. Will try and call Gorr again today, but saw this forum, so I said, what the hey...
First let me tell you what Gorr said the first time I call and the instructions when I got the cylinder back. Basically it said richen the air jet and lean out the pilot, needle, and main. Seemed extreme and the opposite of what I would have thought, but after he explained that the increased volume pulls more gas through the jets that before, it kinda made sense. After calling him one time he suggested putting the needle in the middle if 2nd from top (which is was in middle) and/or trying a colder plug (BR9EIX vs. BR8EIX).
I've tried a few different things, but have it back to stock pilot, needle clip up one (2nd from top), and stock main. The air screw I've tried 1/2 turn out to 2 turns out. Stock is 1 1/2. Plug looks a little dark I'd guess. Not a new plug though. It runs awesome up top. It's around 1/8 to 1/4 throttle its not perfect and coming off the throttle I get that noise that makes me think lean, but with plug dark, I dunno. Maybe I'm just stupid. Definately a possibility... Of course, jetting is rocket science, so...
