125-200cc Husqvarna SM125 2008 RPM problem

My motorbike used to work well, but it was getting harder to launch it, and at the end it was almost imposible.
Only if you pushed it really fast and put it in 2nd gear.
I cleaned the carb and it was really easy to launch it, but first, it had big rev`s when it was idle, (You couldnt minimize it with the idle screw) But when you ran it for a while in idle, or just drow around and pressed the clutch, it reved up, and you had to shut the engine off because you couldn`t get the rev`s down.
It gets rpm up if you turn the throttle eaven for a millimeter. You can usually get the RPM down if you turn the throttle to max and let it go. Maby the throttle cable is getting stuck? Oh, and when you are driving, you dont get so huge RPM, but you sometimes have like Cruise Control. And almost instantly, when you put it in neutral or hold the clutch and turn the throttle, it jumps to high rpm.https://youtu.be/zsp5Nt_Krss

check your plug (what color does it read)

check for cracks in your intake manifold
air screw could be damaged
check your float level in the carb

at 35 seconds before you rev it it sounds just how mine does when my powervalve needs cleaning, it gets stuck when riding so you don't have power the same, I'd take it down to the engine, get in and check that pv motor is turning as the bike revs up, it sounds stuck to me, check the cables that turn it too as they get stuck
