My 2004 TE250 with Leo Vince exhaust... When you are idling and gas it...cough and almost dies.... Jetting is all stock... air screw at 1-3/4 out AP zero preload not sure where it should idle...but the idle is semi wierd...high for 30 seconds low for 30...not sure if it is lean or maybe low float level...no air leaks...
Hey racemx904, I have the same bike with the same exhaust. Works like a charm. Especially with the right carp settings without the dB killer. Three things to try: 1) make sure the carb is throughly clean, especially the idle jet and the air screw 2) The union between the carp and the air box is not porous (check if you spot small cracks, I had to replace mine) 3) Needle position with the dB killer should be on the third notch from the top (stock setting), two down (fifth) without See if it helps. Cheers, Andy
