Okay, got Blackstone's report back today.
The bike is a 1000cc water-cooled V-twin. Filter is Puro ML16818. The oil was M1 10-40HM which was what I put in before last winter. I changed it this time (put in M1 15-50) at only 1350 miles because the shift feel was getting notchy. I know that's very subjective but, that's what I do. Per Blackstone's comments, there was plenty of life left in the oil, so...
Let's see if I can round up the prior UOA, and add this one to it.
UOA #1 was with 2,000 miles (3,000 total) on Castrol ACTevo 10-40;
UOA #2 is 1,782 miles on M1 15-50 Red Cap;
UOA #3 is 1,300 miles on M1 10-40 HM;
UOA #4 is 3,300 miles on M1 15-50
Total miles on the bike = 10,650:

Blackstone's comments:
RON: Wear improved nicely with the short oil run. This is the lowest that we've seen it read, which is a good sign that no problems are developing at steel parts. While it was a little above average last time, it still read well within the normal range, so overall we think your engine is doing just fine at 10,650 miles. No fuel was present in the sample and the viscosity of the oil read normally. The TBN was strong at 10.8 so you had more than enough active additive left to have run this oil longer. Everything looks good from here. Go on back to 3,000 miles next time.
