Synthetic or conventional VR1?

Conventional. The low viscosity surprised me as I've never seen that on a uoa of VR1. I'm happy with the wear metals. Copper I'm thinking is from the oil cooler

I’m a little surprised too that it sheared to the mid-range of an SAE 40 grade after only 1500 miles. I have the same oil in my 2018 Tri Glide with an M8 107 engine. I plan on running it for 3K miles.

I agree that the copper is probably from the oil cooler. Here’s a M8 107 with high copper also.
