Good report for a new engine, no concerns, yes, will be nice to see copper come down over the next 5000 miles, high copper always present in new HD engines.
No real comparisons here on the M8, thanks for posting.
Valvoline 20/50 motorcycle oil in conventional or synthetic is in my opinion = the best.
I do not not agree at all with using a reuseable oil filter over the stock HD one though, not sure of the reason, stock HD filter is well built.
and ... do not agree at all with using K&N filters of any type but thats me. To me, KN = all marketing for less engine protection. Dont get me wrong, if you have a race engine and its going to be rebuilt every few races or years that is another story.
