Break-In

1.) I concur
2.) Follow the manufacturers break in schedule, BUT, focus on HEAT cycles, riding the bike and running the engine get up to operating temperature, then ride it for 50-100 miles at varying RPMs then let the bike cool completely before riding it again.

2) Kinda passed the breakin period (based on mfgr recommendations), so essentially there is no validity to someone stating that ALL bikes require a 2000 breakin period, correct?

2. Yes, no validity. All engines have a little different break in schedule for best performance. For example, race engines are broke in significantly different than production engines. Your Harley will be fine now, just ride it and have fun.

I agree that today's engines do not really require the extensive break-ins that older ones did that had the cross-hatched lines in the cylinders.
I wish I had an article from a builder I read a couple of years ago but.. .. anyhow the jest of it was to crank up the motor and do a short warm up then shut it down and check it over. Then take it out on a long ride and while not wringing it's neck out do ride it at 30-80 throttle for a good long time letting the motor come to a good high temperature. The fuller throttles will force the rings into the cylinder walls more and seat them instead of lighter throttles that allow more of a light scrapping. My last new bike I intentionally picked it up at the dealer and then headed down to a sons house that was about 60 miles away all on nice open and winding farm-market roads. I rode fairly aggressively but with the thought that I was on a unfamiliar bike and was "Breaking it in".
Do not do a bunch of starting stopping light load and short runs.
Ideally at the end of this long run I'd change the oil.
