I changed my oil and after a few rides found that I had a coolant leak from the water pump. I change the water pump and found metal shards in the coolant. I performed another oil change at the same time since there was a lot of coolant around the crankcase seal. I just got my report from Blackstone Labs. I could not be happier with their service and customer support.

Take a look and let me know what you guys think. I changed the air filter a couple months ago while I was swapping fairings. I changed the crush washer and oil filter at both oil changes.
Anyone have any thoughts on the high Iron, Silicon, and Boron?

From your results the iron actually looks good. The boron may be an additive in the motor oil. https://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=729116. https://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=729116

Boron
Used as a corrosion inhibiter, anti-wear and anti-oxidant additive. Concentration levels vary greatly depending on oil brand.

The silicon may be from your water pump change if you used silicone sealer according to this.https://bobistheoilguy.com/engine-oil-analysis/

Silicon
A very common contaminant most often found in a very abrasive solid form, which causes increased metal wear numbers (especially Iron) in oil samples. . Its most common source is insufficient air filtration. However, in my oil analysis report it is actually harmless and due to leaching from a silicone sealant I used to seal a leaking valve cover gasket. Silicon concentrations in such cases as this will typically drop after each subsequent oil change

I used a little bit of grease on the o-ring between the crankcase and the watepump. If that contained silicon I can see that causing it easily. I replaced the air filter a couple months ago, but I'm going to pull the fairings and the filter to ensure it's installed correctly before I take the bike out again.

Checked the grease I used and there isn't any silicon present in it. Odd.
