400SM carb ?'s

[jbrandt]

Ok, so I asked this in the 110/250 forum, but no one knew, so maybe someone here might...

I have a '03 DRZ250, my brother has a '05 400SM. Will his carb work on my bike? I'm looking into upgrading my carb, and so is my brother, so if I could get his carb to work on my bike, that could potentially save me $$. I'd like to think that getting rid of my CA carb and putting the 400SM carb on would give me more power. I'm I right, or way off base. Should I just re-jet the CA carb and be done with it? (I have the usual pipe/airbox mods w/ a K&N)

Thanks!
