There was an article in this month's Motorcyclist about high octane gas and it doing more damage than good. Is it necessary to use 91 in the XBs? There is at least a .10 difference is price between 91 & 89. They said something in the article about saving your money... I'm not a mechanical wizard so just looking for opinions. | ||

Well in the owners manual of your bike it says 91 or higher octane, should be ran in your bike. Trust me there is a difference between 89 and 91. I know from running 87 and 89 in my truck under hard excelleration my truck would ping with the 87 octane but doesnt do that with 89. So i would do what harley says and run no less than 91 i personally run Sunoco 96 in my bike and it runs great. | ||

The lower octane will generate more carbon deposits yes? Every once in a while I throw 110 in mine and it cleans the exit of the pipe. The deposits nearly go away. | ||

91 is not available within 200 miles. normally i run 90 octane in buell, but am currently burning some 87 octane (partial fill-up) with no problems. i dont think these bikes are running a whole lot of compression, but possibly in a really hot climate one might need some higher octane fuel to prevent detonation with extremely high cylinder head temperatures. | ||

My 2000 M2 will ping under full acceleration with anything less then 91 octane. Like clockwork. More then 91 and it is (mostly) OK. (which probably just means I need to set my timing... I did check the VOES and that seems to be working). | ||

most MaDeuces I know rattle on less than 91 (I know mine does, and the timing is spot on factory setting) bottom line is run what the manufacturer suggests (and, no, lower octane fuel doens' necessarily casue deposits, it's the synthetic turn sginal lube that does that) ;-} | ||

NEVER use synthetic turn signal lubricants on your Buell. They are too slippery, and will allow the electrons to slide, rather than roll across the switch contacts, thus causing premature failure. The motor company DOES NOT recommend synthetic lubricants in that application. | ||

NEVER use synthetic turn signal lubricants on your Buell. Says you! I've been running FULL synthetic and have had NO problems at all! And don't give me the ol' it'll void the warranty crap neither. I challenge you (or any "Buell Tech" ) to be able to tell just by looking, which lube I'm running in my turn signals.  | ||

 Well, they used to say the full synthetic will flatspot your switch contacts, but since they released the new Screaming Eagle BlinkLube Full Synthetic, they now say it was fine. | ||

Remember to signal at least 500 left and right turns before changing to the syn turn signal lube, as it is so slippery, that the new signals will not seat properly, and will cause spurious signals in the wrong direction. | ||
