I bought my first new bike today and I am taking it out tomorrow. I know I need to break it in on this first ride/day, but I'd like to do the free mods before I go out again. I pulled off the seat and gas tank to try to look for the grey wire, and I cant find it. Where is it on the 2008 WR 450? What are all the mods I need to do to make it open up? Should I order a YZ throttle stop? I heard there is something in the muffler that needs to come out...what? Does the carb need to be re-jetted or modified? AIS Removal...What the hell is that...I know they sell a kit to remove it...Is it necessary? If you know of somewhere that has the directions (especially ones with pictures) that would be helpful...Thanks guys.
