From 0-200 miles I kept it to 4,000rpms. From 200-400 miles I kept it to 6,000rpms. From 400-600 miles I kept it to 8,000rpms... At 600 miles I ran it to red line regularly until my valves started chattering, and went in for my "1st service/valve adjustment" at around 1,000miles... The biggest thing I focused on was "heat cycles". I would ride 15-30 minutes to work so it was nice and warm, and then let it sit for a few hours while I worked.... Contrary to what some have said, it didn't make sense to me in my mind that a "heat cycle" is mean to heat treat the rings on a cylinder... I just know from working with all kinds of metals that two pieces of metal scraping against one another form to one another better if they're repeatedly slowly heated and cooled together... I have no science to base this on, and I don't care much for the manufacturer's recommendations. Like I said in another thread, I maintain my bike as if it were a person in a loving relationship, so I do what it needs when it needs it, not when the parents (kawasaki) say I should.metbandit1 said:spooph what RPM's did you run your ninja at in break in?
