I just bought an '06 WR450F on Friday. Anybody out there do those "free mods" that i keep reading about? I took the baffle out of the silencer. I also removed the snorkel out of the airbox. I just need to know a couple things to complete the mods before the 15th. First, is the stop screw, to be replaced with one from a YZ or cut, the screw in the carb or is it somewhere else? If I cut it to get the desired throttle response, how much do I cut it down to? Also, where is "the gray wire under the tank"? And what does it go to or what is it for that this makes such a difference? Please help! I need to get these done before the 15th! Thanks!
