Have they rerun that sample to ensure it's accurate?

They did yeah, because they are terrible at reading my submission info so I sent them the oil spec sheet and they reran it.
Amsoil 10w40 with the fuel dilution was still in grade, double the TBN and a better additive package in my opinion. Granted the Amsoil was 900 miles less on the OCI, however my thought is to run the Amsoil again for the same length OCI as the HPL. I try to keep my OCI'S the same length so it can be relatively consistent following the performance in terms of staying in grade, TBN etc. The wear element is what it is but leaves a signature with respect to how well it stays in grade, remaining TBN etc.
Sticking to 2k ish intervals now, trying the 15w-40 HPL next because why not! May eventually return to the Amsoil. Thanks for everyone’s input.
HPL loads most of their oils with moly. However their specific motorcycle oil designed for wet clutches has very little moly.
Redline used to have high moly content in their motorcycle oils and I had no issue with it.
I only throw out those two things as there can be or maybe different forms of moly that might not be helpful to a wet clutch. I assume you're having no problems but I'm interested to hear regardless.

Yeah, I'd have expected the HPL to held up better, considering how much it costs.
See if HPL can whip you up some no-VII 40.
Or, run Valvoline VR1 SAE40, if it doesn't bother you that it's a non-synthetic, non-MC specific oil. You'll never have to worry about shear. My bike loves the stuff. Currently $40/6 qts on Bezos Express.

I could do a straight weight in the summer, not all year though. Sounds like HPL may try tweaking the blend for me once they verify OAI’s results. I changed the oil though so will have to wait until the next fill.
Guess my Lubegard Biotech isn't so bad.

Heck no.
That thread discussing the VR1 40 grade was very informative. Until freezing point, it ran neck and neck with a 20w50 for being suitable in terms of flow.
Here's a paragraph quoted from one of your posts:
@jeff78 said: "Plugging in the numbers for the SAE 40 and 20W-50 grades, I saw the 0C viscosities were close to each other, and significantly below that temperature the SAE 40 numbers skyrocket.
You can play around with the calculator and with enough data points you can plot entire viscosity-temperature curves for any oil you have data for. Note that the calculator is meant for Newtonian fluids (like monograde oils), and oils with VII's behave in a non-Newtonian manner so the calculated viscosities will not be as accurate for multigrade oils. But good enough for comparative purposes - so I'd be able to say with reasonable confidence that the VR1 SAE 40 is thinner than (or at least, no thicker than) the 20W-50 at temperatures above freezing."

Like it’s a bad thing
If you have two different, unmodified bikes set to run off of JASO spec, I would be concerned if they had a wildly different propensity to shear. The horsepower and torque of the motor or rw don't tell the whole story as much as the transmission gear loads do. Is the spec all that generous that an engineer can really rack up the load? As always, it is of course all within the life framing of warranty and reputation costs.
It’s just the trifecta: high loads, high revs, small sump capacity =oil killer.
I believe the sump size is what hastens your permanent shearing, tbn depletion, and oxidation (if you determine any.) I don't think theres a leg to stand on that you are certain it has significantly higher loads, but that's by-and-by from the former.
Absolutely, sump size sucks. There is a leg to stand on in the load department because, again, I keep it under heavy load, wide open, 6th gear pinned and I weigh 200lbs+.

Yes, and the amazing thing is those motors will do it hour after hour. They really are great little motors.

That's great usage. My point is that with respect to the transmission, that's not going to amount to any more shearing than any other bike.

I like it well enough, I just use it to cruise back roads around where I live. I have other larger bikes, but this is perfect for what I use it for.
