I may be jumping the gun here but...
I just adjusted my intake valves on my 87 1200. Also rebuilt a set of carbs (not the originals) with the kits from rpm. I transfered over the floats and the slides from the original carbs to the new carbs. I do not yet have the air box boots installed and figured I try to fire it up. I'm using an auxiliary fuel tank and used some Trufuel premix 2 stroke fuel. It's 92 octane wich is better then the premium I could get at the pump. I used it because it was available and I didn't suspect it would cause a lot of issues for what I was doing.
The bike idles and I was able to sync the carbs buy anything over idle and it will stall out. Almost like the exhaust is plugged. Do you think the fuel is the issue?
Put the airbox on for sure; the bike will not run right without it.. Would recommend straight fuel as well.
If the 2 stroke oil has clogged the pilot jets it will do what you are explaining.

I guess I wouldn't have thought they wouldnt be THAT sensitive but there's a first time for everything

Those holes are microscopic.
When you rebuilt the carbs, did you ultrasonic the carbs?
The pilot circuit is very fussy.

I ultrasonic ed in strait water then blwe out with carb cleaner and compressed air at 150psi. Not my first mikuni rebuild but there's always something new. I need to get more fuel, I'm thinking it was fuel starvation from the aux tank. But only one way to tell
We're all good. I put In almost half a gallon of fuel in my aux and it runs well. Probably didn't have enough fuel weight to push the fuel into the carbs earlier
