2004 KLR stalls when throttle at idle and quick throttle blip

about 3 times a day my KLR 650 will stop running when idling and I accelerate the throttle quickly while at a stop sign or will die at idle when I pull in the clutch to stop. it starts back up fine but is annoying. I hope I described it properly. The bike runs great at high and mid speeds and idles fine it is just once in a while when warm it dies at idle or when the throttle is blipped at idle. Does this mean the carb needs cleaning? The bike has 32,000 miles on it

The carb may need cleaning; it's hard to diagnose from text.

It sounds like it could be lean. Do you have any other symptoms of running lean at idle such as popping in the exhaust when you close the throttle?

Do you have the stock exhaust or have you modified the muffler?

Is the vacuum tube from the carb to the petcock in good condition?

Check fuel (idle mixture) screw; suggest about 1-3/4 turns out from soft bottoming; stock engine.

And maybe, adjusting your idle to around 1200 rpm (knurled screw, spring-tensioned underneath carb) would help sustain your idle.
