Ronis - this motoman guy is too strident in his claims. I think he's right on the money for break-in procedure, but the rest of his stuff is weirdness, and surrounded by mumbo-jumbo "what you think you know".
An example from another of his pages (the most recent) I hate scrolling down 10 pages to discover that he believes main journal wear happens at startup and you should never blip the throttle until oil pressure builds. He may be right - it passes the common-sense test, or his advice does, anyway, but the delivery and tone is bombastic as hell.
Plus, he seriously needs a course in web layout and design.

By the book, every time. Who am I to argue with the recommended break-in schedule of the engine designer, manufacture, and company that is going to take care of my warranty issues?
We most definetly all have our opinions. For 30 years, and approximately 50 brand new motorcycles personally owned, it's always by the book. I've had longevity, high compression, and (knock on wood) zero problems or complaints.
When I've built, raced, tested racebikes, set-up with particular tolerances for minimal break-in, the results are great. But... these results are short lived. The engines are designed to give a pre-determined, fairly short life span before being taking apart and freshened up.
When I've tested magazine bikes on the dyno with very little or no mileage, the hp/tq figures are normally not up to max spec or expectations. As you get miles on them and re-test, the figures consistently higher. Break-in loosens up things, they have less drag (spin easier) and enteria comes easier. A certain amount of carbon build-up, up to a point, can build compression and power. But it depends on what the engine is designed for maximum hp? Longevity? Combo of both?
The pistons noted in the photo's showing a full season of racing in a F3 engine are remarkable. But I simply don't buy it. I have seen extremely clean pistons, run over a fairly long period on nothing but pure canned race fuel. But mix in the daily driver scenerios of low rpm, pump gas, long idles and warm-up, and they surely will not look like race pistons run wfo all their life. Not a chance. You'll have to get other opinions here. He claims to have done this with over "300" engines. Where has he been during the life-cycle? Is he saying he has documented proof of their life cycle over a 10k, 20k 50k mile engine? I didn't see that....
Streetbike manufactures ask for detailed, somewhat long break-ins of up to 1000 miles to ensure long life and max performance of their products. They are confident in their oil change intervals, which most of us adjust based on our own driving conditions.
Even race bikes, such as Motocross bikes require more break-in than he recommends. Yamaha's YZ450F is a stout model. Yamaha recommends I believe 3 heat cycles and moderate throttle settings before going out and appling WFO. They base this on that particular engine design. My point being, every manufacture will have their own parameters. Who is he, but another person with an opinion to question them? I guess only time and results will tell...

I agree with you KB, his is not the first time I have seen this type of information. Having lived overseas for a number of years and in my dealing with engine builders over here I am kinda of torn between the 2. I guess I'll make my decision when my bike gets here. I can't find too much fault with his logic but at the same time time it's difficult to go against the grain of the owners manual. O'well it's only my 2 cents worth.

I'll try to follow break in,and if I do happen to get to get a little carried away and test the rev limiter I'll let her heat cycle.First oil change 250-300km
