87 to 91...whatever I feel like. If all gas (no corn) is available I use that. Really doesn't matter, the bike will run on anything available at a pump unless you have heavily modded it with increased compression, cams, etc.

 

The highest octane available. Usually at Marathon. Whats it going to cost you over 87 octane? Maybe a buck!!!

 

93 octane and when I can find it 93 with no corn! More power and better fuel mileage. I've heard all to comments on this.....corn goes on the grille, not in your tank!

 

+1 on the no corn. I used to run 93, they got rid of it in my area, then 92 until they got rid of that. Now I have to pay attention at the pump, All shells in my area 91 is E10. No good. I now run 91 (no corn) when I can find it. Sometimes on trips I have to use 87.

 

Chevron 91. Runs great and easy to find! Has corn but I like the aroma!

 

91 octane with no ethanol. We used to have 93 octane here, but not anymore.

 

91 from a major gas station plus Lucas gas additive

 

I fuel at Racetrac. They usually give me free coffee.

 

91 is the highest I can find here in creamatoria....if I could find higher I would use it.

 

94 if I can get it. The higher octane the better. If you're on a long haul you can notice the difference in the way it runs and your mileage might be better.
