Hey gang,
new member here ! Waz up ?
I have a 2002 400ex and put a 14t front sprocket on.
I have a Pro Circuit T-4 on the way and have a 4"x8"
opening on my air box lid and installed a Keihin 165 main jet.
I didn't up the pilot, because it starts well and idles fine.
Does this sound like a good set up?
Thanks,
John
