I just picked up a brand new 2009 WR450 and was looking for some guidence. I removed the throttle stop screw which made a huge difference. What other mods do you suggest? BTW I bought the bike from Pioneer Motorsports in Chaffee, NY for 5,499 and they have more if interested. They were very nice but was a long ride from NJ. Does the grey wire mod do much for the 2009 WR?
