A single UOA can be brutal. Especially on a new bike. But when Blackstone picks up a trace, you do have fuel in your oil. My God man, the flash point was 370°F as I recall. Probably should read the comments on your UOA again, but my main point is, totally different engines. A comparison CAN be made however and I'll get to that below.

Pablo, have you seen any UOAs on Vics using recent Amsoil formulations? Were the results similar? I've used Amsoil in past bikes and I always thought they ran good with it, but I never had any UOAs done. I'd consider running a OCI of Amsoil for sake of comparison at some point.
Agree on the general factors. That said this bike does seem to be easy on the oil given the total lack of break in material, or it's just a well made engine. How many years have we been at this? No oil stops break in material, and this one seems low. That's the only thing we can compare to the Ducati, with it's relatively high break in material.
I have said nothing at all against this oil (have I?) I didn't even bring up Amsoil, actually. Kinda why I post less on BITOG anymore and only really post when Amsoil has already been brought up.
I have never seen a UOA of this oil before, and haven't seen an Amsoil UOA on the Victory 1731cc engine. What is the starting vis of this Victory 20W-40? Data sheet?
