Hey guys, here are a couple of pics of my MPS framed (I did everything else myself, and with the help of a local guy, Steve Bonacker). I've raced my bike twice and so far it's performing great and all the welds are holding up nicely. Overall I'm very happy with my final product. I will confirm that George sent me one of those plumbing couplers for my airboot and I just shook my head. I called him and he sent me an aluminum plate so I could mount my original KX 500 airboot to the 450 airbox, which Steve did for me and it looks and works like factory. I'll keep adding pictures and videos over on my build thread (1990 KX 500 Conversion to 2006 KXF 450 - Kwackerman) on here. Cheers, Howie
