However you decide to breakin you bike - hard or soft
the important thing is to be rolling on and off the throttle
as much as possible especially during the first
couple hundred miles. Don't cruise a 2k rpm or 9k rpm
for long periods of time. Accelerate and decelerate.
Riding twisty backy roads is the best cure.
And the most fun.
After a few hundred miles stop worrying about it.
