The grey wire mod is where you disconnect the grey wire from the CDI. This gives you more advanced timing and fuel curves.
The air box mod is where you cut out two holds on the right side of your air box. You'll see outlines of two ovals, cut there.
Mods to the exhaust. My bike came with the PMB tail pipe, but I also took the one of the baffles out of the muffler. From what I read, with the baffle removed and the PMB insert you are right at the 96db mark.
Also, on a WR the throttle stop is longer than the YZ so you are limited to like 3/4 throttle. Take it out and cut it, or go buy the YZ throttle stop.
You can also delete your AIS.
My bike is pretty fast after all that. I'm impressed.

My next step is an aftermarket exhaust. I race alot of GP's on closed course tracks and lose alittle quickness out of the corners to the MX four strokes that I race against. I'm usually the only WR on the line, but the WR is more comfortable to me than a YZ.
Have fun on your new '05's!
