Hi quick carb question... you're familiar with my situation(hopefully you remember my thread!!) with my JIANSHE-YAMAHA ATV250(229cc yamaha clone)(what model clone would that be?? XT? TT? TTR? TW?? Does it matter??).... I have the 30mm CV Teikei carb...it's running very lean, the pilot screw is a 34 and the fuel mixture screw is 5 turns out fron seated...3 past stock assuming stock is 2. The top 3/4 is flat n boggy. The main jet is 96... basically what I got from your information was the 135 round Mikuni jet is what most of you guys are running...I'm going to get the Teikei jets from "Jets r us" tha HumanBeing recommend because they have them...(I just feel more comfortable with them because you said the threads are different with the Mikuni ) what jet sizes do you think would work on the pilot and main?? I'm coming from a 34 pilot and 96 main.... thanks matt. aka "bucklove"
