did you replace all rubbers?

- fuel-rail o-rings
- float valves
- float bowl seals
- pilot screw O-rings

Look down hole when you've got pilots removed to make sure there's no remnants of previous washers & O-rings in there. Make sure you get order of O-ring, washer, spring correct. Insert everything aimed up so everything stays put on pilot screw.

These are static adjustments. Whatever you set them to, it stays and bike behavior doesn't change. Fact that your bike's bike's behavior changes on exact same settings means you've got chunks of debris that's breaking free and clogging holes in carb passages.

Pilots screws also only affect transition from idle to 15-20% throttle up to about 3000 rpms, after that fueling is controlled by needles and mains. Did you poke out all lateral bleed holes in emulsion tubes? Make sure you re-installed needle jets/collars with taper in correct direction?

Also go back to bone stock factory specs. It's already super-rich from factory anyway and only reason people can report better running with larger jetting is that it makes up for dirty and clogged carbs.
