Hello Fellas,
I ride another brand Quad, but My Best Ridin Bud rides the 400ex.
I am alot more mechanically capable and set with a workshop.
This is the situation. He bought a WB E series slip-on and installed it and uses their RevBox as well. He never did any intake mods or Jetting. Now he has the K&N Filter and Wants to run with the Lid Off. I told him he will have to now pay more attn to his maitenance and he has promised to do so. He wants me to do the jetting and install the K&N. At this point i have all the plastic off and the airbox out and cleaned up and the snorkle removed and the Hole blocked off nicely.
I read a great post here on how to go about removing the Choke and have decided that too will have to go at this time.
My question is, do I have decent ballpark figures on the Jetting for this set-up and Mostly Sea Level riding, 42pilot, 2-2.5 turns on the fuel/air screw, Needle on the 3rd or 4th clip and a 155 main jet. Opinions please and thank you.
