What does everybody mean by "properly breaking it in" when you put in a new cam and piston?

do about 2 1/2- 3 hours of light rides. or what i did was just ride at the same speed and keep shifting gears up and down.. just do what you think is proper. dont blow it

as soon as i got done putting mine together i ripped it up and down the street a couple times let it cool down then did it again.i broke it in hard and good and it runs like a rapped ape !
