[QUOTE="motokid837, post: 172425, member: 11092"] I fired up my Lifan 125 for the first time today, and almost immediately you could tell the bike does not like idling without the choke. Even after getting up to temp, and putting the idle screw all the way out, the bike idles for a few seconds without the choke, then sputters and dies. With the choke the bike seems to idle quiet well. Even with choke off and a little gas, the bike runs rough and you can hear slight popping/coughing noise in the intake. So I'm assuming I need to find some larger pilot jets, but here is my problem, the seller on eBay I bought the engine from says the carb is a "no-name" aftermarket carb and does not have a brand name. So how should I go about finding jets? Also, can I still do some WOT runs to get a plug reading on the main jet? That way when I open the carb I can change more than one jet at a time? [/QUOTE]
