OK, I am new to the WR450 forum but I came from the DRZ400 forum and learned a lot. I just baught a 04 wr450 bone stock except for the GYT pipe insert and the GYT throttle stop. It also has been jetted and had the holes cut in the airbox. Besides the grey wire mod, what other mods are there? Should I take out, what looks like a baffle out of the top of the airbox, which would make two small inlets into one large one? Any help is greatly appreciated.
