All the changes to the swingarm and the carrier are on the sprocket side. If you shifted the 400ex carrier to the right at all then there is a slight alignment issue with the sprockets. You probably can't even tell and it probably won't do any harm. I just know I measured this all out a couple of years ago.

250r bumper fits, you just have to bend the bottom mounts out about 1/4" and the top ones in 1/4". This can be done with a bench vise or a pipe wrench very easily and it only takes a few minutes to do. I'm running a 250r bumper and so is a friend of myn, simply because they were at a swap meet brand new for $11.

04/05 450r muffler with modifying the rear mount

Cbr600 clutch should fit the 400ex
450R have lots of interchangeable parts
XR400 engines are the same as 400ex beside the kickstart and the starter
Front caliper of a YZ450 are a good improvement dual piston over 1 and they are a bolt-on

kfx 450r front shocks fit but you have to modify the upper mount by fabricating a wider area to fit the shock in then weld in place. i had to do it on mine
