Oil Pressure/Temperature guage????

It wouldn't matter. Running a thicker oil won't cool it anymore than running a thinner oil. What matters at that point is your oil viscosity. I think (don't quote me) that a 10w30 oil starts to boil around 220 degrees C. Yes, the 1100 has an oil cooler but.. Get stuck in traffic with hot ambient temps, I'd much rather have that 10w40 in mine. I should be running a oil cooler on my CB750, as it has a big bore kit in it but I do not. Hence why I run 20w50 in it, and have not had an issue.

Run what you want, I am sure the 30 won't hurt anything but based on what those images show me I feel better with a 40 in it.
