I haven't had any experience with them because I don't own a 400EX, but I have also heard from a lot of people, that the 426 is more dependable.
I mostly ride utility ATVs, I have a 400 Foreman and a 660 Grizzly and a 350 Warrior.
No, I mostly just trail ride with the occasional deep mudhole. LOL.
I would go with the 426 if you are a pitt rider. You know, haul it in and stay in the same area. If you are a trail rider trying to cover 50 plus miles in a day, I would keep it stock. Nice and reliable.
Sounds like good advice to me.
