Correct Terminology is important.  You need to do some reading. There are no plugs on your pilot jets.

There are dust caps on your air/fuel idle screws and no they are not important.
They are nice to have, but not critical.

No, we don't have those on our carbs.

I have no problem with you being my uncle.... In fact it would be an honor Father Pat.... I already learned how to polish my forks and header tubes with really good results from you. Why not be an honorary uncle.

As a suggestion take the 1 & 4 cylinders and back out the fuel air screws 1/4 to 1/2 turn (give them a bit more fuel air mixture) and take the 3 & 4 screws and turn them in 1/4 to 1/2 turn (reduce some fuel air mixture).  See if your plug readings get better.  I had the same type of reading's and that's what I did. My plugs read pretty close to the same now.

You should re-balance the cabs after each adjustment.

Yea Mark, that was a fun day. We are going to do it again when San Dimas Mike comes out in the fall when it's not so blasted hot....I have a polished swing arm with his name on it

George, I would wait on tweaking the air/fuel idle adjustment until he gets those emulsion tubes scrubbed and cleaned.

OK will do. I had the turns counted first time I cleaned the carb (not good enough). They were all 2 1/2 turns. Tomorrow morning I will take that thing apart COMPLETELY again and soak all jets in carb cleaner and clean every part with a needle. Probably something at the 1+2 carbs is plugged and no gas gets through.

And about the rubber plugs, just wanted to make sure they are not missing in mine.

as i keep driving and she gets hotter is gets worse and into lower rpm ranges too....

Please use the Factory Pro Mikuni CV Tuning procedure...  follow it exactly and go through it 3-4 times from top to bottom.  Your bike is exhibiting classic lean behavior, but the carbs are actually very complicated and you're just going to chase your tail until you adopt a systematic approach.

^^ Yea Chris, that is exactly what I think is happening. Get those E tubes clean, you'll feel the difference.

Sorry for the rubber cap confusion on the video. I'm glad you pointed that out to me.

it really can only be there because the float level is perfect on all 4. #3 still worries me but i will get there. i have to start going to different stores soon when mine runs out of spark plugs. no worries about the plugs. just wanted to be sure because my kawasaki had them.

Just clean them off and reuse them... Nothing bad happened to them right?

well i have the experience with the fouled ones. they dont work well anymore if they get too black even after cleaning them. but i guess i can try it. i had a float problem with my kawasaki and i broke the sparks within minutes until i got the float level correct. i will get up early tomorrow, once again to deal with this. i want to get her running correctly tomorrow!!

Probably no long WHS correct any more, but my dad taught me that to clean the carbon out of spark plugs, stick the cap end into the ground so that the electrode end is pointing up, pour some petrol into the valley and light it..... burns all the carbon out and you can then give them a quick clean and re-gap them.........
Been doing it for years and not a single singed eyebrow yet!... :rofl2:

Haven't learned of this technique before. However, using a propane torch to heat the electrode end up nicely has worked successfully in my past. Past being old two-stroke dirt bike days.
