What grade of gas do you use?

[stevenolts]

I was told by the dealer that the F6B uses reg unleaded gas (87 octane)

What are we supposed to use?

I was bored at work and found a owners manual online .pdf and it says:
Use unleaded petrol with a research octane number of 91 or higher.

I'll have to check my manual but I thought the minimum required is 87 octane.

I have my ecm reflashed for a 91 octane tune (additional timing). My options here are 87, 89 and 93 so I burn 93 all the time now.

I use 87 almost 100% of the time.
My manual states pump octane number 86 (or higher)

Who did your reflash for you?

I live in the PRK, so I always use the EXPEN$IVE kind in this $tate because that is the only kind you can get.

If SB-350 (a.k.a. ) goes into effect to ration gas by 50%, it will probably be more $$$ in addition to being scarce.

Tried all 3 available around Michigan where I live, 87.89,93....Don't notice any difference in bikes power/performance with higher or lower octane...Usually fill-up with 87 (cheaper) run tank half empty then fill with 93 just to make me feel good I guess.....I believe the manual says 87 octane or higher is okay....

+1.....87 Octane.....consistently delivers 40/44 MPG.....no pinging

Thanks Bob,
I forgot to mention the MPG.
I get those same figures consistently and have never experienced pinging even with this Ethanol laced gas.

I run premium either 92 or 93. For the most part gas is shyt. My 9 has a programmer that requires 92. I run it in the B also. Mostly Shell. Sometimes BP.

The cheapest, lowest octane rating I can find in Calif...87 octane usually.
