Hey guys, I got a few questions and I was hoping you'd be able to help. A friend of mine just got a 2001 YZ426, it's his first four stroke. I ahve heard about people running the 03 YZ450 cams in the 426 motors so that they can have automatic decrompression. How many of you have done this mod? What were the results? What parts and/or mods are required? Any help would be greatly appreciated, thanks in advance!
