You don't mention if your plugs have been changed. Always worth a try as plugs and leads are often the cause of stuttering,
Also I would check vacuum lines. Sometimes faults with vacuums can be shown up by spraying carb cleaner around them when ticking over to see whether it changes the revs.

Spark plugs changed too, vacuum lines ok. The bike went to two bike mechanics and one bike electrician and nothing..
In this point i am tired of giving my money away and have no result and because I am a car mechanic I disassemble the cylinder heads to check the valves and pistons but i found nothing wrong.

If the engine stutters "like a missfire" or cuts in and out quickly I think it's reasonable to focus on the ignition system.

You mention "CDI OK, IGNITION COILS OK"   how were these tested ?
