Question about kawasaki KX 450 F Motorcycles
Contaminated or water in the fuel is most likely the culprit here.
drain the tank and carb (small screw at bottom of carb float bowl)
Add fresh fuel from a CLEAN fuel source. Best to completely drain your fuel can and fill it up with fresh fuel. That way if the fuel can is the culprit you eliminated doing this twice.
What happened was fuel sits on top of water, this is why the bike would still idle. The idle circuit in the carb pulls fuel from a higher point than the main jet. This is also why when you hit the throttle it would just die, it was sucking most like something other than fuel.

Not for sure but u might try to re jet the bike.i own a 98 suzuki bandit 600s and it also is really cold hearted. those bikes are unfortunately known for that problem.not that it was much help but u might try contacting Dales Holeshot Performance he specializes those types of bikes he also sells the jet kits.
i would also try to adjust the idle slightly higher hope this at least helps

SOURCE: stalling out
u have the mixture screw wound in to far. its normally located on the bottom of the carb. try winding it out half a turn at a time once the bike has warmed up. also turn the idle screw out a quarter of a turn at the time its in to far thats why it idles at low revs. the choke is needed to keep the air fuel mixture right thats why u are having to leave it on for so long. hope this helps.

It sounds like you probably need to replace the fuel filter, or you may have alot of trash in the bottom of your gas tank, possibly even water in the gas. If you can, take the tank off and clean it out well, making note if there is any trash in it, by emptying it into a bucket so you can examine it. Go ahead and replace the filter if you find any trash or water in the gas tank. If it is ok, then the next thing would be to check the fuel line for aging. Sometimes in rare cases, the hose gets old and weak and when you try to pull fuel through it, it can collapse and essential stop the gas flow, just as if you have turned the gas off, then when the suction is stopped the hose will open back up and appear to be in good shape. You can use your fingers and squeeze the line the entire length and see if it seems to feel excessively soft, if so that could also be causing your problem.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
