Looks pretty darn good, in rough numbers, Iron and Copper are down by over 70% from the first 500 miles and honestly the engine is still breaking in.
I have about 1,300 miles on my current oil so far. I changed it at 1000 miles on my new 14 RK, so all told Im at around 2,300 miles on the bike.
Plan on changing it in the spring, Most likely will be close to 2000 miles on the oil when I do, 3000 on the bike.
Im going to do a UOA on it. When I changed at the 1000 mile mark I used the conventional HD 360 20/50 and most likely will use it again, until otherwise proven I should try something else, which if I did, would be either conventional Valvoline 20/50 4 stroke or conventional Valvoline VR1 but again, for now sticking with the HD.
