Kind of disagree with mvk

The CB1100 is designed to run on 87 octane and up to 10% ethanol (not 15%) and says this in the owne'rs manual.(as most Hondas have been for years)

Running any higher grade of gas than that, is just wasting money. You get no more performance and it doesn't run any "better" or cleaner. Of course, it's your motorcycle and your money.

See ferret i just watched that and took away that I definitely wanna keep using 93 octane. As he mentioned its not for power but he mentioned that factory rating rises if you raise the Ignition timing or go to high compression pistons ( my ECU was flashed and ignition timing altered by guhls) and the 93 octanes having more detergents to keep higher tuned engines cleaner.

Thats why I thought I was always supposed to use 93 to keep all my carburetors cleaner for longer? (The extra detergents)

I appreciate the video tho Idk how I never saw that one on their channel.

Well, the OP in all likelihood hasn't had a Guhl reflash (although it's possible I suppose). For HIM or anyone else with a stock CB 1100 as it came from the factory, the factory engineers determined that 87 grade up to 10% ethanol would be the recommended fuel for the machine.

Using 93 grade probably won't hurt a stock CB, but it's unnecessary, as determined by Honda.

outside of the OP question now I have one

Cause I gotta be honest I'm not 100% sure what exactly ghul was doing to the ignition timing. My understanding was taking out the "factory retardation" but what exactly does that mean? Does that mean they advanced the ignition timing? Would possibly require the higher octane as mentioned in that revzilla video?

I had them do all offered services (raise red line, remove speed limiter, do whatever they did to the ignition timing) but not so sure what that ignition timing service actually does
