2023 FLTRK; Amsoil MCV 20W-50 9.4k mi

I ran this oil much longer than I normally do just to see how it would hold up. I think it did pretty good. I think I could easily change oil at 8000 miles instead of 5000ish.
The fuel dilution was up but I changed the tune earlier this fall. I may need to change the AFR. I drove bike 10-15 miles and it was 40* before I pulled sample so that may have something to do with the fuel dilution too.

Fuel injected?
These results do look good for your bike.

I am not too familiar with this design but if it's a Milwaukee eight engine then it uses roller bearings in the engine. The oil analysis comments hint at bearing overlay and babbitt maerial but that isn't applicable in this engine. You might want to seek a better interpretation of these wear metal numbers based on your engine design.

Yes, it is fuel injected.
Thanks.

Rocker arms and valve guides have brass. Tin could be from that? Not sure how piston flashing makes Tin but at this level not too concerned.

Valve guides can have tin in the bronze, The fuel dilution is probably the tune. Doesn't look bad that I can see.

Amsoil metric 20W50 is in my ZRX 1200 currently. Another 1200-ish miles and I will post a 5000 mile analysis. I don't expect it to be majorly different than any other oil, but interested to see nonetheless.

Brass is copper & zinc. Bronze is copper & tin. Until the current report, copper:tin ratio has been right at 8:1, which is about right for bronze. Thus, I'd assume bronze wear unless I _knew_ Harley didn't use any bronze (bushings, valve guides, or otherwise) in the engine, or had another probable source for the tin + copper.

I’ve got the exact same bike, year and all! You could likely go to 10k on the Amsoil. Glad to know the copper and tin I’m seeing in my sample isn’t an anomaly. I’m using HPL and seeing the same in mine, though mine is the first fill after removing factory fill at 400miles so my copper and tin are higher, though aren’t trending up whatsoever.

You are doing some SERIOUS riding my man! Color me jealous
