the runnning in period isn't a myth, it gives a chance for the engines to settle in and to give a chance for any faults to arise. abusing and modding a new machine will void your warrnty and will also result in your brakes not getting sufficient time to "bed in" leading to unoptimized braking & uneven wear.
i'd say that whatever damage needed to be done has been done and now you should just ride it however you want.
BTW what oil are you using? i hope you havn't been fooled into using a 5W20 or 10W30 as this will kill your clutch.
