I broke it in hard putting just under 100 miles on the first day. I changed the oil that night, then at 1K miles, again at 3K, every 3K up to 15K, switched to synth and every 5K since then up to my most recent 55K mile oil change.
I kept the RPMs varying but I also ran it up the RPM range several times to get a good ring seat.
Or, as I like to put it, I had the front wheel off the ground before I had a mile on the odometer and I read 140 mph on the speedo before I had 10 miles on the odometer.
I didn't need a valve adjustment 40K miles ago. I'm about to check again soon when my Throttle Body Sync tool shows up in the mail and I do that.
