Hi, I am getting two lots of advice for breaking in my 07 WR450f. My dealer tells me to break it in for 500km before he will derestrict it, but my manual tells me to do an hour and a half of break in then go for it. This bike will do 95% woods riding and 5% road work. Thats alot of hours to do 500km. I am lost on just how long these machines need for break in before I can unleash the power of this bike and add a Powercore 4. Also how long to run mineral oil in it. Cheers.........Clinton.
