Just found this site and I'm sure I'll spend far too much time on it! I just purchased a 2004 WRF450. I've read about the "freebie" modes (grey wire, air box, throttle stop, etc.). I'm curious as to those of you that have had your bikes for a while as to what else it needs. I'm a past motocross rider (as in early 80's -- and no, I wasn't very good) and want to get back into woods riding. In the past I typically rode 250 motocross bikes in the woods, had a short stint on 4 wheelers and finished my last ride @ 5 years ago on a CR 500. My decision came down to the Yamaha or KTM. I chose the Yamaha because of my dealer and cost. I'm 6' 220# and really would appreciate your feed back. Thanks, Chuck.
