Another reason to ask why HD wouldn't do this for us then. Why do they recommend breaking them in in increments of rpm limits and no hard starts? Why would they tell us to do it this way if it doesn't work? I'd really like to know if either way is better or indifferent.

Break it in as you intend to eventually use it.Controlled dyno runs with a skilled builder/tuner are the best way to "break in" a new engine.Its time to give up the old wive's tale/urban legend of mollycoddling an engine to "break" it in,especially on a new bike,after all that's what it has a warranty for...

The first time was very un-nerving. The second a little less. The third time, I am good with it.

Dyno is the BEST way to seat your rings.
Controlled environment.
Why would anyone NOT want to break it in under controlled circumstances?

I agree with everything in the mototuneusa tech article. Alloys, cylinders, bearings and rings are superior to when the old school break-in techniques were developed. Tradition has been surpassed by materials and procedural standards.
New school thinking is run it hard. Dyno break in is the way to go. Or in my case.... ride the **** out of it. 17,000 miles and no problems under 12 PSI of boost

Thunder Tower HD Columbia SC. offers a free baseline dyno run with the purchase of a new motorcycle. Even as we speak.

- How long will it take to properly break in a new bike on the dyno?
- Is the flat rate for labor used for time running or overall time sitting on the dyno?
- What is the dyno usage fee on top of the labor rate?
And the number one question - Will this cause a liability shift from the manufacturer to the dealer for all warranty claims on the engine?

How 'bout I break MY bike in the way I see fit and you break YOUR bike in the way you see fit ?
600 miles on the clock and it's going in for Stage I and a dyno tune.
I asked the dealer about dyno runs on new bikes and he said they do it all the time and have never had a problem.
If your skeered don't do it.

No I don't think you are the only one. I preferred to have my built motors tuned on dyno before running on street as it isn't carb and can't run a rich jet therefore I prefer to have it tuned after heat cycles To prevent over heating during the most critical part of a motors life.
