Terse pojat! Again problems with engine...
Why rounds not drop down? Cruising about 4500 rpm. Stop on cross, rounds stay 3000 rpm. Fast pulse on throttle-twist and rounds drop normal idle-speed. Also, in accelerate when up gears rounds want drop. When idle is high, engine runs well, both of cylinders works.
Controls are fine and seems butterflys goes full close even if idle is 3000rpm.

So, what now???

Look at renewing cables and greasing the splitter, and diaphragms in carb I believe a VOLVO one is cheaper and better quality..


Check your choke mechanisms, they have a tendency to stick, leak or misbehave.....
Also look for rotten inlet stub [head] to carb rubbers,,



Carb kits are available including choke rebuild....
 
revs won't drop

it might be worth checking the valve clearances, sometimes if the exhaust clearance has closed a bit the bike will do what you discribe
 
Thanks for hints, bros.
Take carb on table. Open them and blow drills. There was no clean gasoline out, grey stuff. I think its water condensed on fuel. Ok, I have driven 0...-25 celsius. But the master problem found right side butterfly valve. Both of screw was slacken and valve moves on shaft. Lucky pastardo, those screw was not on sylinder.... Tomorrow carbs on bike and testdrive. Hope it works!
