Dead cylinder

Hey my bikes run fine after I work on them.

I really appreciate all the attempts to help, i truely do. But i can see im on my own on this one still. I’ve been battling this thing off and on for probably five years. I’ve been told all the usual things and at this point ive done them all. If it’s the carbs it’s a setting not neglect. Christ knows I’ve inspected every molecule that they’re made of. The only thing I can say is I wasn’t able to re-check the clip settings on the needles because I have misplaced my long reach circlip pliers. Oh how I hate that stinkin design.
im half temped to take it back to stock jetting despite the pods which haven’t been run anyway during this troubleshooting.
Heck maybe I have a mouse stuck in that header!

I have had this bike for close to twenty years. Before the pods it had an airbox that was held together with silicone and ran good but was always temperamental. I’m finding myself working on it again after losing my last house three years ago and finally getting settled in my new home workshop. Every time I get into it i get sidetracked and it sits. Its had a lit of these problems because of the sitting. That’s why I’m full on into it this time. Maybe the engine has just finally gotten too old?

anyway, here’s a list of what’s been and checked
1.wire harness gone through, resoldered, new weatherpack plugs, heatshrinked
2. carbs completely disassembled, soaked, inspected, oringed
3. plugs swapped around, buying new tomorrow if I can find someone open that sells ngk
4. plug wires between 2&3 swapped
5. all wires spark equally
6. pickup coils were bent and repaired (no difference)
7. Valve clearance all in the mid-range of spec.
8. All cylinders get fuel, spark and compression
9. #1,3,4 100psi ( seems low) but are firing
10. #2 130psi not firing
11. Carb slides all move up when throttled. #2 seems to not go as high further testing required
12. petcock vacuum is not getting gas from leaky petcock
13. floats are set to 22.4mm (I measured to top of rounded part not higher squared off portion on pivot end
14. 37.5 pilot jet
15. 24 main dynojet
16. iirr needle clip in 3rd notch down inspection required when i find pliers
17. have not tried hotter plug yet
add more later if I remember more- it starts to get jumbled up in the memory which is why i come here to find clarity again and hopefully someone with more brains than me.

Hey my bikes run fine after I work on them.

i meant no disrespect btw just a chuckle

i have seven motorcycles all of different ages and types that run great. I have one that never runs great. No one touches my bikes but me. This used to be my exwifes basket case. As frustrating as this bike is, it’s more fun than she ever was. I should just get rid of it but i love the engines sound and want to enjoy that again.

Is there any way you can get the ex-wife to lift the curse she put on it? I'm guessing no...

Sounds like a carb problem.

New info
compression is 150 on all cylinders, i was doing it wrong sorry
new plugs d7ea no effect
slides are all moving together so i have vacuum but with the new plugs i can see i might not be getting gas like i thought. Sprayed ether in carb and exhaust heats up.
currently tearing carb down again

Dead cylinder was solved. A pilot had plugged due to the citrus cleaner not getting removed well enough and the brass greened up clogging its orifice. Carbs have been soaked and cleaned again and now I’m tuning for my stalling issue while idling in the carb forum
