That calculation is helpful with respect to the alledged speed the bike and rider HIT the car. Besides discussion on rider vs car driver fault, the main discussion is how fast was he going BEFORE he went into a stoppie through the intersection.

Mobil 1 20w50 is good stuff. I've noticed lately flashpoint analysis from Blackstone, is coming in higher than what the oil is rated at by the manufacturer... Mobil specs Mobil 1 20w50 VTwin at a flashpoint of 214° C (417° f). Blackstone @ 460° f for this sample is an incredible mystery. I...

Fair enough, agree. Speculation is running its course, however common sense says for instance in an NFL football game or an NBA basketball game if a hundred guys in a bar say it was a turnover or a completed catch, it probably was. Not saying there are 100 contributors to this thread, hope the...

That was all on the biker, to think it was an idiot cage driver to blame is a stretch to say the least. The rider may have been a rocket scientist, didn't help him much. The car was completely stopped before the rider even came into the frame, in full stoppie mode with enough speed and force to...

Not to point out the obvious but yes a 50 grade is a thicker oil. It wouldn't have made a difference in choosing the oil, however, IMO, 18.4 cST is not a heavy 50 grade by any means. Supertech 10w40 MC oil starts at 15.8 cST, on the heavy side for a 40 grade for comparison. Mobil 1 4T 10w40...

Or maybe they were stomping on it hard and fast because they had the same problem finding neutral. With the engine off can you easily go into neutral coming up from first or down from second?

Almost 3,000 miles on this oil in the sump of the ZRX 1200. Shift feel has been consistent since day one, as usual the bike hasn't used a drop, everything about the oil says it's doing good thus far. No reason to pull a sample at this point, I'll take it out to 5,000 miles as I usually do.

Thanks for the info on flashpoint. How is there variability with respect to when the oil flashes or burns? To my simplistic mind heat the oil, when it does what it does record the temperature and that should be fairly consistent across oils. Obviously the oil itself, the amount of fuel play...

I'm not aware Blackstone uses dilution based on flashpoint with respect to falling out of grade/cST. Flashpoint helps explain why viscosity may be low or not, but it's an independent measurement of cST that determines the grade in the analysis. It is reasonable to play the game that any...

Where are you located that you found this oil? I've never seen it referenced in decades of riding here in the states. The bike has 750 miles on it now. The early oil changes are usually very much like this shows. Higher concentrations of some elements that are working themselves out of the...

@Japanese, I give and wave the white flag. There's not a winner in this, and imo, discussion doesn't need to get to that point. I'll take what is mine to own and own it.

Oh Lord, somebody's going to be along real soon and question what 0w-40 motorcycle oil you have chosen, despite no motorcycle manufacturer recommending that weight in the history of motorcycles to my knowledge. Good luck!

Does "Fine" indicate will give it a try or are you going to keep leaning on me for answers I have indicated I don't have but reading between the lines it's pretty easy to see what they would be. As I recall, you got involved in a thread about my daughter's car and when other's started debating...

Being absolutely honest, I don't care. You're asking questions that it's pretty clear I don't have answers to and it's a leading line of questioning to continue trivial minutiae discussion. Take a break from Motul and try Valvoline 10w40 conventional MC oil you are interested in with your line...

As said in the post you quoted, I did a UOA. To repeat: Sheared out of grade in 1,400 mi, 860 ppm zinc. Yes, zinc is crucial, that number is low given the option to choose oils that have more and haven't sheared to a 30 grade in 1,400 mi... Flashpoint of 420 is not contributing to shearing out...

What's the title of his videos that I can search and go through them to find it? I would love to watch it.

@Japanese, I see where you're coming from, the comparison you drew is Motul to T4/5/6 oils. I took a broader meaning of MC oils in general and apologize for taking it out of the context it was meant. The Valvoline ATV UOA from the ZRX1200 was not good in being out of grade in 1,400 miles...

Negative, the main thing was the ATV oil that had been mentioned and on sale in a post above, and that I had used it. Didn't mean to imply anything else about the failure other than the ATV oil did not do well with respect to holding grade and is lower zn. Too late to edit, I see what you're...

Mobil 1 4T 10w40 is $10.98 at Walmart. If you're spending more for any synthetic oil, you're paying too much for a product that is no better for that grade, and in many cases not as good @Japanese, what is the difference one would see for themselves with Motul? Have you run Mobil 1 4T 10w40...

Timing advance, makes a big difference in response. With my ZRX1200, I have a connector to run a ZX11 ECU with the ZX11 ignition rotor. Put ZX11 double valve springs in the head, can take advantage of the 11,500 RPM ZX11 ECU red line. However the timing curve is advanced significantly. I've...
