Given the machining tolerances worked with today, the current running in process is more a fail safe for the manufacturers incase there was a human error in assembly.

If a rattle doesn't occur, or smoke start billowing in the first couple rides, give it arseholes!

Aye. And a lot of the brands run 'em up on a dyno before they leave the factory anyway. So if they're happy to do that to a brand spanking engine...it's good enough for me!!

The manufacturers method for running a motor in is about them not being sued by some dumb arse who wipes himself out when working the motor with plenty of on off throttle to bed it in. Check out this link:

Ah this old chestnut

To the OP, do the scheduled oil change and go nuts. Biggest no-no for either run in method is labouring the engine in too low a gear (and keeping at cosntant speed for long periods).
