Hi guys. I bought an eBay Lifan 125 motor for my scooter and I've been trying to dial it in and get it to run properly. I've got it the best I can at this point. I t runs well when I'm on the gas but the idle is choppy and the bike will stall after a while as if its sucking in too much air from the air filter (pic below). Basically I'm not sure if its the shitty carb, the air filter, or the jetting thats causing this problem. Also FYI, the clip position is at the bottom most section of the needle, I'm not sure if that makes a difference. Let me know what you guys think this might be, or if you've run into similar problems and can offer any advice. Thanks !!! :up:
