A little more detail is needed

Has the bike been sitting ?? , if so how long and have you put FRESH gas in ??

Have you checked the valves ??

What is your elevation ??

What jets are currently in it and what is the needle clip position
(from the top) ??

What are the symptoms ?? , are you just riding along and its bogging , then dies ?? ,or does it not bog at all ?? (trail riding or track riding ??)

Are you pulling in the clutch to coast downhill , and it just dies suddenly without warning ??

Are you just shifting and in between gear changes it just dies ??

Does it pop thru the muffler when you let off the gas , and if so does it do it just a little or does it do it a lot ??

Does the idle go up and down , and you have to adjust it , then the next time you touch the throttle its too high or too low ??

If you sit and idle what does it do (for 2 minutes or less) , does it run normally and not stall ? , or does the idle fluctuate and then it eventually dies ?? , or it idles fine , then just dies without warning ??

Carb is cleaned with fresh gas.
I no the needle is in stock position #3.it happens going down hill with the clutch pulled in when I'm in like 3 or 4 gear.when I stop in gear with clutch pulled in it will be fine then all of a sudden stall out.
no popping when u let off the gas.
valves are within specs.
o and it seems like when clutch is in and in gear it drops idle slightly then just dies out

OK , i would look at 3 things , you need to check the Float Level , and you might very well have a worn out Needle Jet , so it should be replaced , and you need to look at the needle for wear marks , if it shows any signs of wear then just replace it as well ,and i would also move the needle to the 4th position (from the top) which will richen the mixture slightly , i would even replace the Pilot jet just make sure everything is clean and clear

The Needle Jet is the long tube the Main Jet Sits in the the Needle goes thru

I have the same bike , and mine was idling weird and dying , and that's what it was , i also replaced the needle itself because it showed signs of being worn (discoloration in spots), and if one is worn the other usually is , the Needle Jet will oval out and allow the needle to rattle around causing the erratic idle issues , basically it is equivalent to raising and lowering the throttle slide , the needle lifts and gives more fuel , it lowers and is leaner , if the Needle Jet is worn , then as the needle is moving around the ovaled out Needle Jet and it will have more space then less space , so the idle will raise and lower , to the point of dying at times, so that will allow it to idle , then just drop off so low it stalls

It is part # 27 , its about $9.00

I would also replace the Needle , part # 37 (OBEKR) $21.00

Pilot Jet part # 42 (size #45 std) $9.50

Replacing those things and making sure the float is set properly (the most likely culpret is the Needle Jet) , should get you back to riding without stalling

I also have a 13oz. Flywheel Weight on mine , it helps tremendously for tight single track riding , i rarely stall mine
