I took short video of it just now, it may help

In fact valve can move with hands but its very difficult and then when i put ingnition on its back to normal, seems servo its not broken then.

But is it normal that is very difficult to move it by hands? and turn it to the left is much harder than turn it to the right (i turned it at maximum on the movie)
and when i start engine i dont see it move

**Edit: Problem solved,i put WD everywhere then i noticed was idle problem, was too high around 2000/trs, so i set to 1000/1200/trs valves start to work immmediatly, good


Then i still got one problem , bike drive good only if i let starter half open... filter clean, carbs clean,start easy, i never touched any carbs setting. Any idea???
