per above, really bad hanging idle, particularly on sand tracks (think southwick).
JD jet kit, 32.5 pilot, blue needle now 4th clip and 440 main.
Anytime I go from long straight and chop throttle into turn I get a ridiculous hanging idle, like the petcock has been turned off. I have gone from blue needle 3rd clip to blue needle 4th clip and it helped mildly, running out of clips. Any thoughts (larger pilot or main) or should I go back to stock needle and see what happens.
thanks in advance.

Air leak or dirty pilot jet or overheating. Also, if sand is getting by the air cleaner it will cause the slide to hang, the same can be said of the throttle cable being dirty.

Check your reed cage, I bet they aren't sitting flush against the cage. This is a known issue to KTM
