James Now on wr450 03 how

I was just wondering if anyone has done the James Now on their wr450? It looks to me there is some dif in the carb manifod.Can this be done? And why is it on the airbox side? I can see if it was on the valve side. But if anyone could shed some light on this? :):D

From what i've read you can't do the James now on the 450, you have to buy the real thing.

Thanks blue, :) do you have the power now?

I did the James now on my 426 and love it, much more user freindly on the trails.
