Did you remove and clean the passages in the carb jets? Or the internal air passages for the idle circuit? These smaller areas are the most likely to be affected by varnish, and being so small, they are greatly affected by small amounts of build-up.

I can't see bad condesors causing most of your troubles, but maybe?.... I am assuming we are talking ignition condensors here. Are you frying sets of points? Condensor's main function are to protect the pionts from power surges when they break contact by absorbing that power. Not saying it's not possible, cause I've seen all kinds of stuff that shouldn't make sense work, just that I don't readily follow it.

And the fact were are talking plural here also puzzeles me. I don't know your bike very intimately, but I know it's a triple. Is there 3 sets of pionts? Meaning 3 condensors?

I would still be looking to the carbs if it was my bike....

if the plug is still in the pilot screw hole, then they are still set at whatever the factory set them at. Very carefully drill out the center of the plug with a dremel tool or hand drill and pop the plug out. using a small screwdriver, gently turn the pilot screw in until it seats completely - do not overtighten it!

once the screw is seated, then gently turn it back out to the proper setting.

It may be that the pilot screw is still gummed up - you can check this by taking it out completely and giving it a thorough cleaning, then putting it back in.

Also, while the float bowls may be sparkly clean, it's possible that the needles and jets may still be gummed up. Pull them out and inspect them carefully.

When you reassemble everything, make sure that you set the floats to the correct height and that your carb diaphragms are intact and have no holes - be very careful putting these back in as it is very easy to pinch them and cause a tear. If your diaphragms have holes or tears in them, then the slides won't lift and it will restrict your air and fuel flow into the engine - opening the throttle won't do anything. (I know this from experience - I had to limp my bike 270km home last weekend with a torn diaphragm. 2 hour trip took me over 4 hours)
