What do I need to do to make the power on my 05 WR450 feel more like the YZ. I used to have a yz but I'm getting lazy and wanted the e-start and lights for the night races. But I was surprised at just how much of a power difference there was. I know about replacing the throttle screw with one from a YZ, cutting the gray wire under the tank, and taking out the 82 db insert in the exhaust. Please give me some ideas, this things a turd.
