Put it under load for a few minutes, load it but don't rev it to redline.
but don't rev it to redline.

That may be true if all the new components, (not just the piston & cyl.) expand at the same rate, and that the "full operating temp" doesnt vary much in any given situation.
The big deal is loading the motor to seat the rings.
Thats a given,....
My experience with KTM 4st's is that they tend to run a bit on the warm side while new, possible due to tighter tolerances when new.......(shrugging shoulders)
There are some personal preferences when 'breaking-in'.
