Title: 400ex jetting
Post by: wchughes5 on April 02, 2005, 11:53:55 AM
Does anyone know what size jets to use on a 400ex with a pro circuit slip on and a k&n filter with the lid on? I was thinking maybe a 158 or 160 and a 40 pilot.

not a bad start, may want to consider a 45 pilot,165 main  and the needle clip on the 4th notch
