idling problem

[xman23]

alright i have a 84 200x and it always idles good, but i havent rode it in winter at all till about 2 weeks ago, i start it up and its hard and it idles fine, well i have to give it alittle gas for like a minute to keep it from dying till she warms up, then after riding for a lil while when i stop it kills, i had a 120 jet in there fom summer becuase i have a oversize headpipe and aftermarket slipon, so i moved up to a 128 and still same problem, then i went to a 138 because the other ones it was running lean and now its alot better for that reason but still kills after its warm when i come to a stop, any ideas
