Just a quick fill in here, this is a new bike, I received a PM request to do a engine vacuum sync, bike is somewhere under 10,000 miles, I mentioned EVS wasn't needed if you are having no problems. So this was several days ago, it now looks like he does indeed have a problem.
I am in the process of putting my 2015 back together @ 11000 KM, I found one exhaust valve tight @.20 mm instead of .22 to .31 mm, intake I had several at spec. 0.15. I am not going into detail here as I have some news as to simplification of doing this valve shim job and will do a new posting in a couple days. I will say all my valves are now at maximum clearance ( intake ) 0.21 mm and ( exhaust) 0.31 mm .
So Harun, you need to tell :Idle RPM=
Take a picture of instrument @ idle.
Can you make a 10 second video with sound? ( ya I know , if you could do this you wouldn't need help in the first place)
My guess is you need a throttle body vacuum sync but as Steve in Sunny Fl has pointed out much earlier, you probably have some tight valves causing the vacuum to be off. So I hate to say it but you may need to do a valve shim check first, continued running under these conditions could cause permanent damage.
