Don't baby it but don't cane it either.... that's about it in one sentence.
Ring "seating" is done a lot sooner than you think, the first 50km's are probably the most important.
I agree dyno best place to run in a new donk, however your average bloke who has just picked up his new bike from the dealership this wont apply to. Just enjoy your new bike!
I always change the oil and filter at the 100 km mark as the majority of metal shavings will be out and about by then. I do not use Harley oil for running in either, just a good quality 5L pack from Supercheap as its getting flushed in a 100km anyway.
HD shop gets your bike in a box, puts it together, tech test rides it....unless you put it together yourself and you are the test pilot the rings are already bedded or not when you ride it out the door, no expert here but I'm told that due to different metallurgical compositions than years past it all happens pretty quick. Recently read from an engine builder that it is a waste of time heat cycling as well, better to just ride it.
agree gm,and welcome back,been on the tools a long time and yes things have changed,construction/materials used,better machining quality control and oil capabilities pretty well ensure easier and better " run in period ". service intervals on a lot of brands have been streched out to make the most of todays engines and oils.
In that case beages I've got nothin.
LOL at your final comment.
