Standard procedure is 2 and half turn anti-clock wise i.e. if the air screw is screwed in but care has to been taken when screwing it in do it very slowly and with less efforts so as not to damage the point.
Best to adjust this air-fuel mixture is to let the bike's engine reach normal running temperature than you adjust ...you can go a little plus or minus depends on many other factors.
Valve clearance too have to be checked and set according to the manufacturers specs. Hope this helps!
Hi, Sakaresrini it should be noted that the "AIR FUEL" mixture screw adjustment "ONLY" manages your idle and has no effect on any other circuit also any intake leaks must be repaired before the A/F adjustment procedure can be performed otherwise you will never obtain a proper idle and you will waste a lot of time chasing the impossible. The A/F mixture screw's purpose is to fine tune the fuel charge entering the combustion chamber. The following applies to both 2 and 4 stroke engines:
1. The mixture screw may be sealed at the factory with a Welch Plug please review the following video for removal. https://www.youtube.com/watch?v=wAXcksgvDkM
2. The mixture screw manages a range of 3 complete 360-degree counterclockwise turns from the bottom/closed position.
3. The mixture screw should have a spring and o-ring for tension and sealing integrity.
4. Turn the mixture screw clockwise until it gently bottoms out, this makes the fuel charge very lean and the engine should not idle if it does then the pilot/idle jet is too big and needs to be replaced with the next size smaller.
5. Turn the mixture screw 1 and 1/2 turns counterclockwise to establish a baseline for starting the engine.
6. To fine-tune the idle circuit, adjust the mixture screw 1/4 turn in or out to achieve maximum idle RPM, wait 15 seconds between each adjustment for the idle to settle.
7. Never go past 3 full turns out this will make the fuel charge rich, foul plugs, and produce black smoke out of the exhaust, if the engine RPM keeps increasing past 3 turns the pilot/idle jet is too small and needs to be replaced with the next size larger.
8. After achieving maximum idle back out the mixture screw another 1/8 of a turn then adjust the throttle cable idle stop screw to 950-1050 RPM.
9. This procedure works great on 99% of all engines, for the 1% that demand a more robust throttle response on aftermarket monster fuel delivery systems additional tweaking outside the box may be necessary.

Hi, Shailesh and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset

Hi, Sazedul you need to make sure you have no intake leaks by spraying some Brake Kleen, Contact Cleaner, Starting Fluid etc. around the intake manifold and seals, if the RPM's go up or down significantly then you have a leak that needs to be fixed before you can continue with the carburetor adjustment.
The engine should be at operating temperature with the enrichener off to set the idle between 950-1050 rpm. Turn the idle adjuster clockwise to increase the idle speed and counterclockwise to decrease the idle speed. If you have access to your air fuel mixture adjuster you may adjust it as well if not there is a video below on how to gain access, make sure you start with clean or new spark plugs. Gently turn the air fuel mixture adjuster clockwise until it starts to bottom out "STOP" do not over tighten as it will damage the taper on the end, now back it out 1-1/2 full turns to establish a starting point start the engine and check the idle rpm's and turn the idle adjuster accordingly for 950-1050 rpm if necessary, turn the air fuel mixture adjuster 1/4 turn at a time and let the engine settle for about 10 seconds, clockwise for a leaner mixture and counterclockwise for a richer mixture you are seeking the highest rpm your air fuel mixture adjuster can acquire without going past 3 full turns from bottom then readjusting the idle adjustment back down to 950-1050 rpm If you can not detect any rpm change and can not stall the engine by turning the air-fuel mixture adjuster all the way in then your pilot/low-speed jet is too big and needs to be replaced with the next size smaller. Final adjustment should be made with a clean air filter mounted to the carburetor.

3. Idle speed improperly adjusted.
4. Dirty air cleaner element (may also affect idle speed).
5. Vacuum piston assembly malfunction.
6. Excessive accelerator pump output.
7. Plugged or restricted bowl vent.
8. Fuel level too high.
9. Loose jets.
10. Worn or damaged needle or needle jet.
11. Enrichner valve not seated or leaking.
12. Plugged air jets or passages.
