[jones711]

OK so I have a yfz450 and a 400ex when i was jetting my 450 i seen on the 450 forum every one that owns one put there bikes set up,elevation and weather temp.made it easy to find out what size jetts your looking for all you do is look for your bikes set up and there it is, if not its a damn good starting point,,so why dont we start it on 400ex's since so many people own them and always looking for that right jet :D :D

in florida, with my mods, at sea level, with a stock carb i use a 220 main "seriously" and a 42 pilot... with a 450r carb, a 50 pilot is right on, and with a 190 main im a little lean towards topend. needle clip has stayed at the stock position for both carbs.
