Stock carbs? Have an airbox? Manual slide carbs? Opening them too fast? Lots of possibilities here. More data would help.

Could be lots of things.....dirt carb, incorrect jetting etc

My 2001 ZX6E did the same thing.....after cleaning all the carbs and not finding anything terribly dirty......while putting everything back together I found a vacuum hose had hardened and fell apart....reconnected and problem solved.

Ok closly obb my carbs while running I note that the two on the left at the needle jet I do not see fule (at idle) the two on the right I see fule (At idle)
When I lay on throttle it will almost stall if a graduly twist trotle it will run fine . In higher rpm I see fule at the neddle jets on left side . The bike seems
to have better compressin at idle on the right two that fule is apparent at needle jet the left side has compression but not as well i think .
Sory about the hack job spelling not so great at that .
Also it will (sometime) idle down fine Others it will very graduly idle down slow .

From your description I'd guess your pilot jets or passages are clogged. Having the carbs removed and carefully cleaned will most likely solve the problem.

Could be a stuck float or bad float height adjustment. If this bike has the factory jets you will not be able to get it running right with the airbox off.

Did you remove the floats?
Yes ! I cleaned all the carb . . . my guess is a float . Funny I knew nothing
before I pulled apart and now im catching on .....:-o I hope ! Ill pull apart next week . I have to weight to I have a day off work .
What a pain in the *** it is just to back off the allen head screws that hold them on . I have a easyer time deling with the carbs than getting them off .

It's a bit difficult to say whats going on when in the video. With unknown choke setting, throttle position, etc at different times during the video and with a cold engine to boot. Bogging out like that on a cold engine doesn't surprise me. I'd try to get the engine running right at normal operating temps. Then pursue any other problems but I'm not sure if you are saying you have throttle control problems or what but I'm guessing you do since you have the throttle apart in the vid. So I guess my question at this point is why is the throttle apart or what are you attempting to fix with it right now?

The Throttle was apart because it was sticking open Ie not enuff slack .

Butt the prob is when I lay on the trottle from iddle to wide open it will stall .

OK, you need to resolve the throttle issue and get that put back together. Then it wouldn't hurt to keep the throttle visible in the vid when you rev it so we can see whats happening when. Also, you need to get the engine up to something close to normal operating temp before doing the test. That bogging could be because the engine is still cold.

Check for air leaks. Could leak (suck air) between the intake tubes and cylinder head? Leak between intake tubes and carbs? Even, possible leak between carbs and air box (air filter)?

Many times after having removed carbs and/or intake tubes. These areas may not have sealed up completely, after re-assembly. Especially, if they havent been apart in a while.

With engine warm at idle. Easy check for this, is to spray a small shot of starting fluid or carb cleaner thru the space around the carbs and cylinder head, it will not take very much starting fluid at all. If there is a leak, the engine will speed up some. No change in engine speed, no leak!

If it leaks. Re-check all the areas that I mentioned in the first paragraph above and make any necessary repairs or adjustments. Hope this helps!
