			If the engines are that precisely constructed...wouldn't it negate the break in period?  I am starting to think the break in period is a hold over from the days where engine construction tolerances were not as precise.  Sport bikes do not need a break in period....as long as the engine is at operating temperature it shouldn't matter.  If metal shaving etc. were present...wouldn't Porsche require a oil change at 1000 miles?  I religiously followed the break in period...but if it really made that much of a difference then why do the test drive cars at a dealership routinely go above 4000rpm?  I think this might be out dated...what do you all think?
