Which Octane Gas?

So I use 94 octane gas all the time. Coming off of a sport bike, I felt like the bike preformed quite a bit better. Now Im a Spirit and wanted to know what octane gas do people use? Any experiences? I think my mind wont allow me to put in lower octane gas, and the few times I have, in the back of my mind I think it is sounding different and not as powerful, etc.

I used 87. I found that putting in higher octane gas was actually making my bike run worse and could also have been contributing to lower gas mileage. Others here have better explanations for why the lower octane gas is better.

because it is less expensive for one and because the owner's manual says to use 87.

My bike performs noticeably worse on mid and high grade fuels

Unless you're running a turbo or higher compression, there's absolutely no need to run anything higher than 87. The higher octane rating helps prevent predetonation. In my Turbo GTI, I run 91/93 because of this. When I had my old Chevys, I ran whatever was the lowest offered.
There really isn't much of a gain from it from my experience.

Run what runs best. My manual calls for 91, I use whatever is the lowest grade, 87, most of the time. I do use higer octane gas on occasion, if only for the additional fuel system cleaning properties of premium fuels.

87 costco......NO need for anything else. Fuel doesn;t need to burn slower to ignite.

So is the rule of thumb to NEVER believe anything a mechanic says? I had one honda shop tell me run premium to keep things clean on the inside. Stated they get a lot of bikes running 87 and having to have carbs cleaned out because of it.

Who do we believe if we can't believe the mechanics? Should we believe only people who are mechanics or go by the manual only. If I were to go by the manual only I wouldn't of adjusted my pilot screws.

It's all a mess!! To stay on topic I run premium. I don't notice it running badly. I fear I may not know the definition of badly.
