I had a couple boxes waiting on my step when I got home today. :)
I bought a used stock 450r bumper. It seems to be of nicer quality than the 400ex bumper. I pulled the old air filter out and replaced it with the moose racing one I had ordered. It looks to be pretty much the same as the stock one. The last time I tried to clean a factory honda air filter, it fell apart in my hands, which is why I replaced it. I also installed the seat bushings that make it fit a lot tighter and better.
