    What kind of gas do you pump into your bike?

    Came across an interesting thread on the busa forum about this, turns out I'm not the only guy that runs 87. I ran 91 in my gsxr 1000, but 87 in both my TL and Busa and it runs way better then premium IMO.

    Also I usually only fill up with Mobile/Exxon or BP. Had the worse fuel milage with Shell.

    I have always run premium in my bike till I read a thread the other day as well. I put mid grade in it last fill up. Can't say I noticed a huge difference. I will run her dry and put 87 in there and see what she does. Alot of guys were saying theirs runs better as well with 87 or so.

    I was running 93 since it was only .60 a tank. A lot of guys on the GS forum say they only run 87 and it runs better. My owners manual says 85-95 octane.

    I haven't really noticed a difference in the half tank of 87 so far.

    It depends on cylinder pressure and timing.

    My truck runs best on 89 octane with a stock tune. But it was designed for 367hp on 87 octane. 93 octane on a stock tune only helps with heat and load (hot day pulling a trailer with the AC on), otherwise it's a waste of money.
    Buy made in the United States. Otherwise your job might be next. Unless you already wear black shoes and a visor with golden arches on it to work in which case your fellow american has already failed you.

    93 The factory calls for 91 or better and while I have run 87 in the past and not noticed a difference, I figure it's not worth the risk of messing something up due to detonation. I don't know how anyone can say they can or cannot hear detonation on a bike when the engine is spinning at 14,000+ rpm.

    87 octane on a stock tune is faster.

    i run 93 only because of the tune is for it.

    read up on psychobike.com/forums and they will all say the same thing. the 87 is the way to go.

    the MR9 race gas from VP is 87 octane equivalent too


    maybe i need to see if the 87 will run better with the current tune?

    I run 89 minimum in the tiller, pOrk told me to run 87 but I could hear it start knocking when it got to operating temp. It's fine with mid or higher

    With a whopping 64 horse out of the fatboy I think 87 octane is plenty good!

    I've always ran 93 in all of my sport bikes, i guess i just assumed they were set up to run on higher octane due to the compression and timing.
