Do you guys run premium fuel? It's what I always fill up with and it seems to make my bike run smoother - any negatives/positives about this? Oh yeah and when you guys change your spark plugs do you use a torque wrench to specific 9ft-lbs or just go a quarter turn past snug? Thanks!

 

I ran 91 non oxygenated fuel in my F3 and use it in my F4i as well.

For the plugs on my old F3, I did quarter turn past snug.

I run 87, somtimes 85. Im also at 5000+ feet and I herd you dont need higher octane this high up anyway. Never noticed a difference.

 

i run 87 and use my redneck calibrated hand to what i feel is tight for the spark plugs

 

None of the above.... uses 95..... :-)

 

Win.
I couldn't have said it better myself.

 

high octane 105 cause I like to go faster.
wait... it doesn't make you go faster?
well damn.

 

93! Premium!

 

Lol - Thanks for the answers! It's what I figured and i'm glad nobody buys the thieving 89 gasoline right in the middle.

 

I run 93 in mine. I get better mpg with 93 and I don't have to remember what vehicle or bike gets what lol. All we own gets 93. I could have put 91 but since 91 isn't really around here I started the 93 and after I noticed some kick in performance as well as the better mpg I never stopped.
