+1 lugging is the worst thing you can do to the motor new or broken in

just ride it like it is going to be ridden the rest of its life. If you are a slow / lugger rider then do that. If you are like me, fast off the line, run through all gears, cruise at 70-80mph then ride it like that from new. just my 2 pennies worth......

I think the article you read applied to an engine rebuild. New bikes are run in at the factory, and the rings should already be seated.
If you watch the "incredible factory" shows on the History channel, you will see one on the Harley factory, with techs running new bikes on the dyno. If they don't perform to specs, they are rejected.

No, static engine runs do not seat the rings, even on a dyno. It needs the "load" of actual acceleration and deceleration for this to work. This works on engine rebuilds, but is primarily intended for new break ins for ALL 4 stroke motors, bikes, cars, etc. Please check this link:

The first one is on a dyno. Up here in the frozen north, many rebuilds are done in the middle of winter and the engine is broke in in a warm shop on a dyno. As far as load, check out the weight of the spinning drum in a dyno.
