i've got a 2003 warrior and i'm looking to upgrade the carb, put the white brothers e-series on it, k&n air filter kit, .190 douglas rims front and back, itp holeshot mx front and back, just to get the edge on my neighbor who also owns a warrior. So i've looked at the white brothers racing carb, is it worth my money or is there something better.

 

If money isn't a big concern, try finding an Edelbrock Quicksilver carb, externally adjustable accelerator pump and you install different needles for rejetting, also from the outside, so it is very easy to set up. On a 400ex, they were getting 3-5 hp with no other mods, might be a good upgrade for a Warrior. I have been thinking about one for my Wolverine,since it has the same motor.
