I think this UOA looks real good and I hope mine comes back like yours.
I guess my statement tells you what I think, looks good! No issues, meaning no out of the ballpark high numbers, your copper is pretty good, Id be more concerned if it was above 175, and even then, I would just hope it is half that on the next change, I dont think you can ask for a lower copper number on a new RK, we have oil coolers and would expect that number to come down by around 15/20% each time you change. Silicon, no big deal, Im sure it will come down.
I have a 2014 Road King, Bought 8/14, I changed the oil at 1000 miles and put in
Harley 360 (20/50 conventional). I will post a UOA sometime mid to late Dec. Trying to get some miles on the 360 oil, lots of rainy weather here but should be out on the road today, sunny near 80.
Im not sure what I am going to replace the Conventional Harley oil with, normally I use something a little lighter in my bikes for winter. Last winter I did a mix of 2 quarts Valvoline 20/50 motorcycle oil and 1.5 quarts of the same oil in 10/40.
I may also just run one of my favorite 15/40 diesel oils or possibly the Valvoline 20/50 syn since syn is a bit lighter for the cold. Never used a syn in a bike before though. Ill figure it out!
Anyway, thanks for posting this UOA, I would love to see one on your Valvoline motorcycle oil when you get it back. Its no secret Im a big fan of Valvoline oils. Up until this Harley I have been using their conventional 20/50 4 stroke motorcycle oil and have a great UOA on it from my last bike, a Vstar 1300.
I choose the oil not because of the low cost but beause of the great UOAs AND Amsoils 2009 Study of motorcycle oils the darn Conventional Valvoline 4 Stroke Motorcyle oil beat and met many of the synthetics in the gear wear test and 4 ball test, pretty impressive for $4. a quart and I can change it more often. Pretty impressive that out of all the oils in the Amsoil test they choose Valvoline Conventional oil to compare against their synthetic and all thge other synthetics!
