Struggled with this one for a long while - took a bit of back to the basics thinking to finally figure it out.
Had a bike that was sooting up the plugs, leaving them wet, running with no off-idle power.
"Must be running too rich"
So I knocked myself out trying to cure that.
It was at the point where I had the pilot screws open only 1/2 turn that I started to think I had it all wrong.
I fixed a bent rod on the enrichment circuit - still ran rich. Poured half a bottled of Seafoam into the tank - got better but still ran rich.
Threw my hands up and said "F it!" Took it out on the road - struggled but once it got up to temp it smoothed out somewhat. Real pain in the neck to ride, because it struggled to get past 1500 rpms - but once you got past that it zoomed to 4k. Barely got warm.
Turned the pilot screws out to 1 1/2 turns, tried it again - almost serviceable at this point.
Guess I'll turn the pilot screws out to 2 and see if that doesn't get it to where it needs to be.
My best guess - once I figured out the enrichment circuit, I had it leaned out so much in the idle circuit it was starving for gas and in order to get it over 1500 rpm I had to open it up and dumped in too much fuel - sooting up the plugs.
Lesson - if you find yourself needing to go to the extreme on an adjustment, you're solving the wrong problem.
