this weekend i've been workin on my 03 400ex. yesterday it was spitting and popping and backfiring. i took the carb apart, and cleaned it. the jets in it are a 38p & 146m. the needle is on the second clip. today i reinstalled the carb, and it fired right up and idled good. no spitting or popping, but that was with the choke on full. when i turn it to half it idles up for 30 seconds or so then slowly dies out. so, back to full choke and it idles fine, but when i turn the choke off, it shuts down in a few seconds. i have to start it on full choke, take off riding then turn the choke off.anytime i get off the gas it will die if i dont constantly blip the throttle(i.e. wont idle). the other thing is, when i park it and turn it off, gas will run out of the float bowl line. i 'm gonna take the carb to work and soak it in the parts cleaner this week, so at least it'll be clean. i've got some main jets that say: dj138, dj142, dj155, dj160, dj162 on their little baggies in the moose kit. dont know what to do. :confused:
