Re: '..it is humbling..'
Something everyone should realize every day. No sense in worrying about it much...'cuz what one doesn't know will always and forever far exceed anything one DOES know. And that's true even when you throw in the stuff that some think they know (and don't)!
Instead, enjoy the search for and procurement of knowledge and information.
There is always room for more when it comes to things that need learnin'. Might as well have fun doin' it!
Don't lose sight of what all this (bikes, riding) is supposed to be, at least for most of us. It's supposed to be fun!
So...get to it!!

CC,
when you say the CEK-4, do you mean CEK in the number four position? This was the setting I tried most recently, but reverted back to the original middle clip (#3) because of some crackling under load (too rich I believe).
Here's something I noticed, not to dispute your comments about the value of plug reading. In the #3 position, my plug appears rich after a idle-1/4 throttle run, but dry after a full throttle run. Might this be resolved by changing to a less steep taper? By my assessment, the same needle diameter with less taper would allow less fuel in lower throttle, and more at higher throttle.

You can't not tune the air screw with a modified carb. You will never get it sorted out.kicknrocks wrote:haven't messed with the AS yet
CEK-4: The '-4' is the clip position..as noted in the graphic.
On a general note...if your preference is a clip position that is different..great!! As long as the method you use makes some sense, the conclusion you reach that suits you is what you're after...not what everyone else says.
In regard to method, specifically..will a less steep taper resolve the 'too rich' on the 'bottom' you describe?
Fact is..that is exactly incorrect. Other things being equal, a steeper taper is lean LONGER (through a throttle pull) than is a lesser taper.
IF that's a 'DOH' moment for 'ya...fine. If not..say so and I'll say why it's so.
The RB carb originally came with an AEN needle. Smaller taper, so leaner on the bottom of the pull? Uh...absolutely not. MUCH richer. That needle was SUCH a goober.....it was a complete mess. If the bike wasn't 4-stroking it was because you were eating lunch or taking a pottie break.
