Right. Carbs cleaned very carefully. Dried with compressed air.
After carb sync, bike started run on all 4 gears. Idle is still rough as it was, but it's not worse.
You won't believe there is still the same issue, but now it looks different.
It stutters mostly on revs lower than 6k, but this is no clue it can stutters than runs fine, after few yards it can stutter again.
If you have high rev and add lots of gas it will stutter for few sec than go like rocket.
If you have medium&low rev it can stutter for few sec and start to accelerate normally but can die as well.
Basically now I don't think is the carbs issue. I am going to check ignition coils and ECU again (I've got replacement). If not then I will buy ignition coils. If it don't work then all I can do it's sell my bike
... but already invested too much effort. I want to really fix it.
