Hi !
I bought many parts from the Power Parts catalouge for my 400 EXC .
the fan : it´s perfect part for very difficult trails , never boiling again
plastic skidplate : strong and light
black plastic: much better quality and fitting than UFO
high black seat : unbelievable price
brake pads rear and front: I use now always the original, a little bit more expensive but the best one what i tried at the moment.
EXC silencer: lighter than stock and better performance in the bottom
In the usa there are also some online-Shops :
