Fully synthetic or not.

"Bob is the oil guy" - lots of mentions of the CB1100 on this subject. 10W-30 and 15W-40

I just find it awfully easy to choose the spec. the manufacturer states, it takes all the guessing out of it. I find the biggest impact on my bike for gearbox smoothness is the correct adjustment of the chain slack.

I believe that is actually the info that I referenced when I made the oil/oil filter cross reference table thread for members. Lots of info on that site

This was the thread. In hindsight I don't think i used the proper verbiage to explain why the 10w-50 is used over 10w-30 according to my bike shop.. but I was just trying to relay the info at the time lol.

The list of filter serial numbers should still be accurate though

I have been using the Mobil 1 M108 or M110 depending on price and availability. Has anyone here used the Mobil M1MC-134 motorcycle specific filter and noticed any difference between that and the M108/M110 or the Honda OEM 15410-MFJ-D01?

The CalSci post you referenced shows the thread and PSI ratings, but I can't find anywhere that references the Honda 15410-MFJ-D01 specifics on PSI. Obviously it has the same threads, but I am curious to know if those are truly an identical replacement as CalSci suggests.

Asking because I am wondering if I should be using the motorcycle specific Mobil M1MC-134 .vs the M108/M110.
