In other words, not currently verified. Yet he has issues with JASO verification.BLS, I like the caveat in small print below the three samples you shared.

It's clutch compatibility. For the millionth time.....The chief JASO requirement is registration fee of $365 per oil...
JASO does not test oils... They only register oils based on manufacturer
data where most of it is generated by additive package manufacturers...
Mercy Moto... Did you ever find out the status on the 2021 update to the JASO standard???It's clutch compatibility. For the millionth time.....
Doesn't look like there is anything new as of today; the 2016 spec is still the most recent. All up-to-date info can be found here: JALOS: JASO WebsiteMercy Moto... Did you ever find out the status on the 2021 update to the JASO standard???
It could be that JASO wasn't even around in 2000. My '98 Honda Super Hawk calls for a 10W-40 SE, SF, or SG. No mention of JASO...My 2000 Valkyrie doesn’t say anything about JASO.
However OPs 2018 GW is quite specific and lists JASO T903 Standard MA. Not sure I’ve ever seen one but that’s the standard Honda wants, not just JASO.
Not sure what the T903 is. Does it show up on the bottle?
T903 is the JASO spec for 4-stroke motorcycle oil. It's shown on the bottle only if the JASO logo is used on the bottle.Not sure what the T903 is. Does it show up on the bottle?

There was a slight revision to the 2016 version, but they didn't roll the version number probably because the revision was minor. The latest 2016 JASO T903 version 2016 notates the revision on the first page.Doesn't look like there is anything new as of today; the 2016 spec is still the most recent.

Is there concern of the 5w sheering faster than the 15w?Without hesitation, 15w40 0r 5w40 both work well.

I just looked at the 2000 Hayabusa owner's manual. Only says use API SF or SG, no JASO call-out either (too early in JASO timeline). Even says 10W-30 is OK, but only if max ambient temp is 30C (86F) or less.It could be that JASO wasn't even around in 2000. My '98 Honda Super Hawk calls for a 10W-40 SE, SF, or SG.

Not at all. Just buy what ever they have in stock, that's the problem. This shearing thing is way over thought. I've run both in Harleys, Suzukis and Hondas for more years than I want to remember. To be honest I've been running Mobil 1 15w-50 lately and have zero issues with that also.Is there concern of the 5w sheering faster than the 15w?
