I'm looking at getting, most likely, a yz400f. I now have a 2001 yz250f with the auto decompression cam, I hated the decompression lever, so I switched and loved it. I was wondering if I can do the same on the 400/426. Do I use the 450 auto decomp cam? Or is it the same cam as you put in the 250? Simple question, but I can't seem to find a straight answer on it. Thanks!
