White Brothers E-Series Jetting

[Hondaman90]

I just got my White Brothers E-Series Slip-on. I'm putting it on a stock 2004 400EX. I also got the White Brothers Power Filter with it. When I put it on what jet will I have to change to? Thanks

I'm not sure, this might not be the best jet but it works for me fine. I run a 155 main.

I DIDNT REJECT WHEN I DID MY WHITE BROS PIPE AND FILTER AND MYNE RUNS BEATIFUL.

OK Thanks, I'll see how it runs when I put it on. How many discs are you guys running on yours?

every quad is different on the jetting and it also depends on the height above sea level

We just drove it with the E-Series on it and the sound difference was amazing! I counted 7 discs on at right out of the box. I am running stock jetting for now. I am going riding on Saturday and I don't want to get there and have something go wrong. Is there anything I should do at all before I go riding? (Add discs, Take some out, anything at all) We went down the street and it didn't back fire on deacceleration if that means anything. Thanks

take that hex head wrench along in case u have to take some discs off. im not running my powerfilter on it runs great the way it is.

My Powerfilter isn't on either and its running fine. I thought about putting it on, but I figured if I put a filter on it would mean more air. And more air would mean it would need more gas. So I might have to rejet it if I did that. By the way does the Power Filter do anything because it looks just like the stock one, except its red and black and it might be a little bigger.
