ask any engineer, riding hard does not seal the valves… especially if the engine is cold…
the break in period is basically allowing metal from the pistons to transfer to the bore and vice versa, which removes any play and leaking in the system and greatly reduces the friction of these parts moving against each other… this is actually very similar to breaking in brake pads, you start off slow with moderate braking and slowly step it up…
at the risk of sounding sexist, pretend your bike is a woman… if you want her to stick around for a while, buy her flowers first
