Fair question -- answer is kinda subjective (as is the need for the 1,000 ppm question at the head of the thread)
==================
Back in the days of old, when the Kings ruled the land ....
.... actually, back in 1980-90's oil was 10w40 and it was rated SF-SG-SH during the decades without a lot of change in the grade structure other than to add more detergency and more long life anti-wear chemistry.
Oil had 1,400 to 1,600 ppm of ZDDP commonly and flat tappets were the vast norm in engine/cam/tappet technology, not the rare exception as it is today. There was no rule saying you HAD to put in that much, but if you didn't your oil wouldn't work so everybody did ....
Then came CAFE and catalytic converters and the API SJ standard. ZDDP got a cap of "no more than 1,000 ppm of ZDDP" with the SJ standard.
SM dropped it to 800 ppm
SN dropped it to 600 ppm
..... and Savage engines started dying from the ticky knocky syndrome. Faster and faster, more and more.
Meanwhile, back in the Kingdom, the heavy duty side of things was changing too.
The Heavy Duty Engine Oils started out at 1,600 ppm like the best general car oils had, then they dropped to 1,400 with CI and then dropped to the current CJ standard of 1,200 ppm of ZDDP.
Three months ago, I would have told you that 1,200 ppm was a good ZDDP amount as all HDEOs had at least that much and MOST of the expensive motorcycle oils had a lot more, but none of them had less than 1,200 ppm of ZDDP. And it would have been true.
Right now, every new VOA I see on the new SF/SG/SJ motorcycle oils are coming in right around 1,000 ppm of ZDDP. I do not know what rules drove this change, but EVERY SINGLE ONE OF THE LOCALLY AVAILABLE JASO MOTORCYCLE OILS HAS REFORMULATED / REBOTTLED ITSELF IN THE LAST 2 MONTHS
.... I am still hoping to see higher numbers from somebody, but so far 1,100 is the highest seen. Lucas is the lowest, at 800 ppm, and it claims to be JASO motorcycle oil too.
So, you now understand where the current 1,200 ppm ZDDP SuzukiSavage standard came from, and how the 1,000 ppm ZDDP that you can currently get out of a motorcycle oil shows up in the topic question up in the thread header ....
..... and why we are having this discussion. If we only need 1,000 then we are golden. If we need more, we need to use HDEOs exclusively until we can find some bike oil that has what we need.
Or else be like Boule and Dave, go get yourself a bottle of ZDDP booster and start using it.
And the bike oil people still aren't saying boo about what they just did. They used to be willing to tell you what was in their "new and improved" formulations mainly because it really was new and improved.
Now we are getting SF/SG/SJ obsolete API standards loophole-style run-arounds instead of facts.
==============
Have cat converters started showing up in bikes big time? Will the same change that looks to kill off the carb equipped bikes in 2013 usher in a wave of catalytic converted equipped motorcycles ???
