Dude we are talkin break in.....12/13 RPM???
we are talking break in
do you know what a "breakin period" is for?
its not some magic moment where things are stupid fragile on the motor cycle
its a point and time where the rings are wearing down the high points in the cylider walls, and on them selves, providing a better seal
same with the valve stems, and the guides
and the same with the cams
, and well ever other moving part in the motor ... oil pump, all that good stuff
as long as every part has proper oil (it better, or there is bigger issues) there is no issue
part of the hard breakin theory is that the rings, and other parts will wear to a pattern that suits the higher rpms that the motor will likely see the rest of its life after breakin, this not causing a SECOND series of wear conditions, thus reducing the over all parts wear during the "breakin" cycle.
