I have done the Joe Minton recommended break in the last 4 Harleys I've had. He says with todays fine tuned machining and factory refinement that really all one needs to do is properly seat the rings and that is not done by babying the bike. Run the bike 10-30 miles to thoroughly warm it up and make sure there are no strange sounds that would indicate loose or mis-assembled parts. Then get the bike up to 35mph in third gear, give it wide open throttle to 65 mph then release the throttle letting it engine break back to 35. Run this third gear cycle from 35 to 65 back to 35 ten times without stopping or touching the brakes: you're done, the rings are seated. This should be done at a comfortable time of day, not over 80 degrees and where you have room to accomplish without traffic. After seating the rings you still shpuld vary cruising speeds for the first 1000 miles and avoid the liberal use of redline RPMs but you can ride pretty normally and rev freely through the gears. HD says change oil at 1000 miles. I changed the engine oil and filter at 250 after this breakin process. I'll still take it in to the dealer for initial service by 1500 because HD and the dealer insists on the first service done by the dealer to validate the warranty.
Mintons article was in American Rider Magazine. This link is from Mototune and has similar info:

I had a friend break his in just as Harley said and the thing used a Qt of oil every 1000 miles from day one. My SE doesn't use a drop in over 4000 miles nor did my RK Custom.
