What size main jet?

[dave4881]

If you have successfully re-jetted your 400EX, please list the mainjet you are running and which brand, and which exhaust you have.

Ex: 148 Dynojet, HMF slip on

Thanks!

lol....jetting isn't that simple dude. And it's not going to be the same from one person/bike to the next.

Nice thought though

DUDE, It will serve as a starting place for those that want to rejet their 400. I realize there can be slight differences from one ATV to another. Altitude can also be be a factor in jetting.

Do you have anything constructive to add or do you just like to crap on other's posts?

There's another thread with all of this info on this site. It's probably 300+ replies. But anyway here's mine:

Yoshimura full RS3 carbon fiber, 152mj & 42pj. Keihin jets.
