05 DRZ Carb Issues?

Recommended Posts

I am working on a 05 DRZ 125 and am a little baffled. I completely dismantled the carb, soaked all appropriate parts in carb cleaner over night. I blew out everything with air and reassembled. It now runs (didn't before) however it idles and will rev up only with the choke on. If you shut the choke off it stalls out. You can keep it running if you have it revved up and then shut the choke off, but as soon as you let off the throttle it dies. When it revs up it crackles and pops a bit almost like a small backfire. I have reset the mixture screw to 2 1/4 turns out to see if it needed to be richer, but at this point it will only perform with the choke open. Anyone else have any ideas, valves, re jetting? Any help would be appreciated.

it needs a new pilot jet at least one maybe two sizes bigger than stock and you may want to plow that circuit out again.
