Changing to dino oil and thrashing the engine isn't going to help those problems at all (and probably won't help a real ring issue either).
Yes maybe, but there are still two facts that seem to be discounted in these discussions: rings still have to be seated and synthetic oil is slipperier than standard oil. So there is no doubt more risk with engines that use synthetic oil during break in.
While one may find riding a little more aggressively during break risky, there certainly is no risk with using dino for the first 1000 to 3000 miles, none.
The one advantage of breaking in a motorcycle is the standard transmission. By the nature of riding a motorcycle, we apply more back pressure on the rings when letting off the throttle to allow the engine help slow us down. Corvettes with automatic transmissions (delivered new with synthetic) seem to fall prey to burning oil more than the standard transmission guys. The only car I have that burns any oil is my wife’s automatic Suburban that she broke in. I’m not sure she ever drives over 30 mph and she is in no hurry to get there.
One doesn’t have to ride like an Indianapolis 500 driver to break in an engine. Just riding normal in town will do pretty good job provided they let the engine help slow them down. No aggressive riding there, and a few normal accelerations on to a highway sure wouldn’t hurt either. 90 percent of breaking is done in the first 50 miles anyway, so the real break in doesn’t take that long.
So while there are those who say dino oil isn’t required for a good break in, my thoughts are that it sure doesn’t hurt.
