YZ timing will complete the transformation, and may indeed make a difference in your jetting, but not nearly as much as the other exhaust and intake changes IMO.
Therefore I think you should try YZ jetting which will work better with the freer-breathing setup.

My 426 hasnt been jetted, piped or YZ timed and the power is perfect for trail and playing at the track. If you are racing at the track, thats a different story. I changed the gearing and cut the grey wire. I tried the YZ timing and didn't like it. Lost a little on the low end which doesn't work for my riding style. I have ridden with guys that have been jetted and piped and all the other stuff. For me, I didn't feel it was worth all the effort and headache. You are what makes your bike faster, not jetting and pipes and all that stuff. The free mods fine tuned my bike to be perfect for me. If you feel you WANT more pull then maybe you should, but if you are doing it to make you a faster rider, it won't do that unless you are riding your bikes to it's limmits on power. I really dont think to many people are doing that.
