I worked as a mechanic at a Ford dealership for a lot of years and was always amazed by some of the wing-nuts that would wander through the doors. Its amazing how many "experts" are out there who have never turned a wrench but they heard something from somebody somewhere so it must be true.
That being said, I always enjoyed talking to people first hand, especially when they had a concern or issue as it made problems much easier to diagnose. I was also always willing to share my knowledge with people who were interested in learning.
I suppose I could have opened my own shop but I watched my dad work 24/7 with his business and there is something to be said for having regular time off, not worrying about overhead expenses, personnel issues etc. etc....
As for proper break-in, I certainly don't have any concerns about Gliders method. Any method is fine so long as you vary the engine rpm and load, don't overheat the engine, and most importantly, don't lug the engine. Modern big twins like to spin, both during, and after break-in.
One of the most important points is the oil change. Always better to change it sooner rather than later in order to flush out any debris.
Enjoy your new machine! Your biggest concern at this point should be deciding where to go on your next riding adventure!
