I am getting ready to install my new WB E-series full system this weekend and just wanting to know what some of you are running for jetting on your 400ex. should i just put it on and run it and check it or should i go ahead and install a step or two bigger main jet at the same time i install the system or just try it stock. any help is appreciated.

ill check my sizes, as soon as i ge it back from the shop

Dont rejet right away. test it out and see if the quad is running lean. the directions for the e-series say that the pipe is designed for powergains without having to rejet. But since you have a whole system you might have to go up a main or two. I tried rejetting my 250ex right away. (this was before I read this in the pamphlet. It screwed everything up. So try it first. You can always adjust the pipe to your stock jetting by the amount of disks in them. try it and see.

I have a pro-meg by white bros. and I had to go to a 170 main jet

The discs are for changing where your power hits. 1 disc=bottom, 14 discs=mid, 28 discs(the most you can put on)=top.

Me and my friend both ran the E-Series pro-meg pipe on our 300's and mine came out with a lot better performance than his beccause he didn't jet it. later he went back a did and was much happier
