View Full Version : Jetting again



04-08-2002, 07:39 AM
I understand jetting, but will have to remove my carb to get @ the needle & jet ? I ride a 2002 400ex with K&N air & the spark arrestor out. I have all the jets but I’m still looking at pipes.
I think I’m going to get the Yoshimura Silencer over the W-B & I want to do it all myself. Any thoughts or suggestions would be helpful.
